DAHUA NVR2104HS-P-4KS2 & NVR2108HS-4KS2 & NVR2108HS-8P-4KS2

Because the home has been renovated, if you need too much wiring, it will destroy the overall pattern, not to mention it is very conspicuous, and it will also destroy the overall environment, making people feel abrupt, and the first thing that comes to mind is naturally the wireless monitoring idol Head, I have been looking for it for a long time from a certain east, and from the current point of view, the price is still good, I can buy some for around 300 for DAHUA NVR2104HS-P-4KS2 DAHUA NVR2108HS-4KS2 DAHUA NVR2108HS-8P-4KS2, but when I was looking for it in April, none of them were lower than 450, and they had to match. A video recorder or an old computer as the host computer is used to store video data. In this way, a special space needs to be reserved to store the host computer or the video recorder, and the electricity bill is also a lot of expenses (compared to the plan I selected. said), considering the continuity of video file transmission, the test of wireless router is also an aspect, the use of wifi at home is still dependent: smart TV, mobile phone, computer, and IPTV, if video surveillance is added, it may be It is also an expense to upgrade the dual-band Gigabit wireless router;

After consulting the students who are monitoring in the local computer city, the students told that the wireless monitoring is not stable enough and the price is a little high. If I want to fix it, I might as well use an analog head. He has an old video recorder and an analog head. Use, if you want to use it, you can get it. But I went to the scene to see the effect of the analog head. I really feel that even if I put it at the end of the living room, I can’t see clearly through the door. I feel that the pixel is similar to the camera used on the computer, and it is not clear enough, maybe only about 50W. Then give up the analog head; if you choose a high-definition network camera (not WIFI) AND DAHUA NVR2104HS-P-4KS2 DAHUA NVR2108HS-4KS2 DAHUA NVR2108HS-8P-4KS2, because when the decoration was originally made, it was the wifi network that was decided to use, so the wiring did not take into account the monitoring, and the reserved lines were not enough, then you need to wiring, this scheme is also denied;

I think for today’s thieves, if a video surveillance head that needs a video recorder is installed, if the thief knows how to do it, it can destroy the video recorder or hard disk, so video surveillance is meaningless. Moreover, in terms of cost, if an ordinary security monitoring system is installed, one monitoring head is not cost-effective. The most common video recorder is four-way. From a cost-effective point of view, it is the most cost-effective to install four heads. The one-time investment cost will be relatively high, although it is nothing compared to the loss of theft, but based on the principle that money should be spent on the edge, I have been discussing with the leaders and decided to give up this plan.

Using a concealed miniature camera solution, according to my classmates, this kind of surveillance market is not allowed to be sold publicly, only one can be found on a certain treasure, but the electronic products of a certain Tao are mixed, and the actual effect may not be useful. , and I wanted to achieve the effect immediately, so I thought about whether there could be a system, preferably using a wifi network and storing it locally, but if necessary, it can be triggered and transmitted to a certain place in the network according to specific conditions, Network disk, mailbox, etc.

I happened to see the information about the Raspberry Pi in Aunt Zhang, so I thought of using the Raspberry Pi in combination with the official Raspberry Pi camera to complete a relatively hidden DAHUA NVR2104HS-P-4KS2 DAHUA NVR2108HS-4KS2 DAHUA NVR2108HS-8P-4KS2 surveillance, and uploading the pictures and videos to the Internet to save, so that even if Monitoring is broken, data is not taken. It will be of great help to solve the case and minimize losses. The most satisfying thing is that this solution just needs to find a place for the Raspberry Pi, a credit card-sized host, and give him a power supply. , Others use the existing wifi and wired network, plus their own network programming capabilities, the later expansion will be much better, because I just came into contact with the Raspberry Pi, I don’t know much about the performance of the special camera for the Raspberry Pi, yes There are also doubts about the video recording ability, but I am very satisfied with his high-quality photos of 500W pixels, and then I found an alternative to video surveillance on the Internet: Dahua’s picture surveillance, which uses a fixed time interval of photos to form a time frame. Axis, to a certain extent, is similar to video surveillance.

In this way, the plan to use the Raspberry Pi to set up my monitoring system is basically determined: less money, less wiring, and small changes to the home layout. Although video monitoring has been changed to picture monitoring, it can be improved in the later stage.
But the problems also follow. The yeelink platform is a start-up platform for a startup company. The stability of the platform and whether it is free in the later stage are also unpredictable, but in the current situation, it should be no problem to use it for a year. Using this time, you can use the web solution to save the pictures saved on the camera to your own paid space, or directly save them in the external hard disk on the Raspberry Pi, or even trigger the video recording function in combination with the human body infrared detection module. In this way, the combination of video and picture monitoring can not only save storage space and network bandwidth, but also play a good role in preventing theft.

Dahua Technologies, a globe-leading movie-centric intelligent IoT solution and services company, has introduced its AI NVR4000-I Sequence, including DHI-NVR4208-8P-I, DHI-NVR4216-16P-I, DHI-NVR4216-I, DHI-NVR4416-16P-I, DHI-NVR4432-I and DHI-NVR4832-I. Distinguished from mainstream NVR merchandise with solitary AI purpose in the market, the Dahua AI NVR Series integrates perimeter security and encounter recognition, providing customers expense-efficient AI transformation and upgrading with higher-precision safety ensure whilst preserving labor price.

My first NVR was Dahua NVR2104HS-P-4KS2. At that time, I liked to take pictures of flowers and plants. After seeing my photos, an uncle said to me: “You ask your father to buy you a better camera. , look at your camera, what you shoot is clear in the middle and blurred around. “Although this sounds a bit like a joke, it’s a real thing, expensive cameras won’t take pictures of the surrounding clearly, Maybe in the hands of a big-aperture madman like me, it will only make the surrounding pictures more “blurred”. So expensive camera must be good? Yes, expensive cameras must be good, after all, in photographic equipment, you get what you get for every penny, two cents for a dime, and three cents for a dollar. Appropriate. My second camera was a ipc-hdw3849h-as-pv, and I was actually going out to work and earn money with that camera at that time. For example, when we took the picture upstairs, we looked down from the top. The snowflakes above our heads were Christmas sprays. When spraying, we had to spray them down and blow them upwards with an electric fan; the deer on the far left was wholesale.

I bought it in the market and cost 75 yuan; the gift box on the left was bought from the express delivery company and bought a few empty cardboard boxes, and then used colored paper to paste them up and tied them with ribbons. So after playing photography for a few years, the best thing I learned was crafting. Maybe you will ask why the snowflake doesn’t block the eyes or something, why the model’s posture and expression are so good, classmates, in fact, I took dozens of pictures and then chose one picture. So shooting a magazine is an extremely tedious job. The pictures of the clothing factory were also taken with ipc-hdw2439t-as-led-s2. The process was too difficult, so I won’t say it. This set of films was filmed and earned money for a DAHUA NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2,DH-NVR2108HS-8P-4KS2,DAHUA DH-NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2 Price. All by Dahua NVR2104HS-P-4KS2 6D In fact, I have also used 6D to shoot a lot of things, such as the above. With the change in the nature of work, I can come into contact with a variety of different cameras every day, and I have since entered the pit of 1DX2 and played with this machine every day. The stability of this machine is naturally nothing to say, and it is not once or twice to work with this machine in rainy days.

And it’s too cold outside in the winter in the north. If you take a micro-single shot of the scenery, you can either hang a power bank or bring several batteries, but the 1DX2 is not so delicate to use. Can one or two degrees below zero be called low temperature? If you can’t take thousands of photos on a single charge, is that a flagship phone? 1DX2 F8.0 1/125s ISO 100 Compared with other models, the flagship machine rarely has color faults during post-retouching, and the post-production space is particularly large, and the two different styles of skin tone can be adjusted without any violation. and sense. 1DX2 uses the USB 3.0 interface, so the transmission speed of online shooting is very fast and very stable, and it can transfer a Raw+JPG to the computer within two seconds, so that you can shoot commercial pictures, edit or be present directly from the external monitor.

Seeing your picture, you can also make a picture preset directly with Capture One, so that they see the color you want to show them in the end, and they can immediately feedback to you if they have any questions or needs, which is very convenient. Aside from studio shooting, the flagship machine has obvious advantages in daily shooting. The pleasing color of the display screen and the accurate white balance are one of the advantages of 1Dx2. This group of photos was taken with 50 1.2. I can directly hold the display screen like this and show the finished photos to the young lady, so that the young lady can directly The selection is marked. Large aperture fixed focal head such as 50 1.2 / 85 1.2

These two heads are also one of Dahua’s advantages, which can be more convenient to use in low light environments, especially such as indoor lighting and other portrait-like portraits, large aperture lenses It can blur the cluttered background, better reflect the atmosphere of the space, or use a lower ISO to obtain a better picture quality. In fact, the NVR2104HS-P-4KS2 in these pictures only uses 100 1Dx2 Aperture 1.4 Shutter 1/200 ISO1001Dx2 Aperture 1.4 Shutter 1/125 ISO1001Dx2 Aperture 1.4 Shutter 1/125 ISO100 Of course, I will definitely not just show you the camera screen, the positive film still has to be released, this is shot in a restaurant in Beijing “Hong Kong Style”, liked 100, and I will tell you the name of the restaurant. This restaurant is open until 4:00 in the morning. When I went there at 12:30, there were many people taking pictures. After one o’clock, The people in the restaurant are almost gone. The picture of the film that comes out is clean, the post-production space is relatively large, and the color transition is better. You can modify the film to any color you want in the post-production period. Some people have asked me what is the difference between taking pictures with each brand of camera. Everyone takes a picture by themselves.

may be more tiring to take portraits. 1Dx2 aperture 1.4 shutter 1/125 ISO100 is reflected in the skin tone as shown above hahahaha. 1Dx2 aperture 1.2 shutter 1/8000 ISO100 full-pixel dual-core CMOS AF application is particularly advantageous when shooting backlight, using the traditional optical viewfinder to take pictures in backlight will be shaken by the sun to a short period of dizziness, so I often It is to use the live view focus and look at the screen to shoot the backlight. After the introduction of the full-pixel dual-core CMOS AF, the focus speed is very fast, and the touch screen is very convenient. 1Dx2 in latitude

The word home video recorder really shows the age. Since the advent of DAHUA NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2,DH-NVR2108HS-8P-4KS2,DAHUA DH-NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2 Price, the video recorder has gradually moved away from the daily family life. But recently, because my LD is about to start school, I specially ordered me to prepare a video of sports competitions for her, and I have to cover all the schedules so that I can do research and study.

After a brief thought: the games are mainly broadcast or recorded on the Central 5, and there are also online platforms, such as Tencent. Taking the recent World Women’s Volleyball Grand Prix as an example, DAHUA NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2,DH-NVR2108HS-8P-4KS2,DAHUA DH-NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2 Price can only download SD videos, and Tencent videos can be downloaded in HD, but firstly, it must be played on the client (encrypted), and secondly, there is no commentary. After thinking about it, it seems that I can only record the TV broadcast myself.

The first thought in my mind was that I needed a TV card.

In fact, it should be called the capture card more rigorously, but in the analog signal era, the home capture card is basically connected to the cable TV cable to watch TV or for entertainment such as Xiaobawang, VCD, DVD, etc., so it is also appropriate to call it a TV card. When I was in school, every dormitory had a CCTV interface with a full range of channels, and I could watch Jade TV and Phoenix TV, but the space was cramped and I couldn’t let go of the TV. So with the upgrading of the computer, I have used Harpaco’s WinTV-HVR-1200 TV card (PCI-E interface) and Jiademei UTV332 TV box (USB 2.0 interface).

Hapag WinTV-HVR-1200 TV card Hapag WinTV-HVR-1200 TV card

Jiademei UTV332 TV Box Jiademei UTV332 TV Box

Following this line of thought, I first opened the search (wan) search (neng) index (tao) engine (bao).

Both broadbands have opened iPTV, but according to the previous telecom settings, this time it took a detour.
The iPTV of Zhejiang Telecom I am here, if it is in bridge mode, you need to connect the LAN port directly to the DAHUA NVR2216-I2,DAHUA NVR2108HS-4KS2,DAHUANVR2104HS-P-4KS2,DAHUA DH-NVR2216-I2,DAHUA DH-NVR2108HS-4KS2,DAHUA DH-NVR2104HS-P-4KS2,NVR2216-I2,NVR2108HS-4KS2,NVR2104HS-P-4KS2,DH-NVR2216-I2,DH-NVR2108HS-4KS2,DH-NVR2104HS-P-4KS2,NVR2216-I2 Price,NVR2108HS-4KS2 price,NVR2104HS-P-4KS2 price,DH-NVR2216-I2 price,DH-NVR2108HS-4KS2 price,DH-NVR2104HS-P-4KS2 price, and the iPTV will dial and authenticate itself, that is, the telecom optical modem can be directly connected to the router with a network cable in bridge mode, and a The root network cable is directly connected to the iPTV, which can realize Internet access and video watching respectively.
However, according to this connection method, I found that Zhejiang Mobile’s iPTV authentication failed, indicating that the address could not be obtained. After contacting China Mobile, I realized that Zhejiang Mobile’s iPTV needs to be dialed before it can be used, that is, the light cat is in routing mode. All the LAN ports of the IPTV can be directly connected to the iPTV; after switching to the bridge mode, the iPTV needs to be connected from the main router.
After understanding the difference between mobile and telecom iPTV, connect the mobile iPTV to the LAN port of the main road of the dual WAN, but the mobile iPTV still cannot be authenticated, indicating that the address has failed.

Subsequently, the mobile staff set the iPTV to wireless mode, and the iPTV could obtain the address assigned by the main router, but still could not authenticate.
Considering that it was possible to open iPTV before, the mobile iPTV could not be certified only after the dual WAN was used. It is suspected that the double dialing caused the failure of the mobile iPTV certification. Randomly disconnect the preferred WAN (telecom), only use mobile broadband dial-up, the problem is solved, and the mobile iPTV authentication is successful.
The next solution is simple, bind the mobile DAHUA NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2,DH-NVR2108HS-8P-4KS2,DAHUA DH-NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2 Price to IP, and then designate it as mobile broadband.

With the popularity of the Internet and the improvement of security awareness, more and more people are considering installing a security camera. For individual households, installing a security camera at the entrance can easily see visitors during the day or night; For people in the hospital, those uninvited guests can be avoided; as a commercial street store, one can visit the store, and secondly, the parking spaces outside are monitored, and customers can park with confidence to avoid unnecessary disputes.

For outdoor cameras, first of all, they need to have certain waterproof and dustproof capabilities, and they need to adapt to different ambient temperatures. In addition, different cameras have various functions, such as enabling remote viewing anytime and anywhere; such as providing humanoid detection functions, Once someone appears, it will send an alert to your mobile phone; for example, full-color night vision, you can see color images even at night, so today I will recommend a few cameras to you, I hope everyone can find a camera that suits you

2. First, try the ER130 of Yuangang, which is the one tested by Aunt Zhang.

Looking at Taobao, it may be that I don’t know much about the capture card market. So I looked at the product line of AVerMedia – oh yo? The ER130 seems to look good! Offline use, scheduled video recording, local editing, remote control operation,DAHUA NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2,DH-NVR2108HS-8P-4KS2,DAHUA DH-NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2 Price isn’t this the video recorder in the high-definition era? ! Turn to Jingdong, um, the evaluation is also good. So I opened Xianyu. Although the number of second-hand ER130s is not high, I still managed to find a set, 9 new +, all required and all legs and pieces of paper are not lost, and a video splitter (for cracking HDCP).

Excellent Perimeter Security for Enhanced Alarm Accuracy
With the outstanding perimeter safety purpose, the Dahua NVR4000-I Collection can significantly reduce false alarm and carry higher accuracy functionality to end-users. The potential of the new NVRs to filter out untrue alarms triggered by animals, rustling leaves, brilliant lights, and so forth. permits secondary recognition of the targets, therefore improving alarm accuracy. Aside from, the NVR4000-I series is capable of examining targets based mostly on deep understanding algorithm to differentiate individuals and cars, therefore making retrieval far more effective.

Sophisticated Experience Recognition with DH-NVR2216-I2 price numerous Apps
The AI-run experience recognition technologies driving these goods enjoys a high popularity in the industry, winning numerous initial prizes in global competitions. Becoming acknowledged on overall performance for equally effectiveness and precision, Dahua Confront Recognition delivers true-time facial analysis by determining, capturing and recording faces with powerful metadata. Merged with configurable a number of face database, frequent and stranger mode could alarm for suspects on blacklist, making it possible for passing for authorized folks on whitelist, also inform for approaching of strangers.

Reliable AI Search for Increased Efficiency
Dahua Technology, a globe-leading movie-centric sensible IoT resolution and provider service provider, brought NVR four. with new UI and new expertise that tends to make every little thing less difficult for end users. The new NVR four. supports key Dahua NVR types such as NVR2000-4KS2, NVR4000-4KS2, NVR5000-4KS2, NVR4000-I, as effectively as NVR5000-I.

Then press Ctrl+X to save and exit The connection behind http, you have to replace it with your own. If you are using a usb camera,

You need to install fswebcam first, it can realize the function of taking pictures with a USB camera.

sudo apt-get install fswebcam

Then create yeelink.sh

sudo fswebcam -d /dev/video0 -r 320×240 –bottom-banner –title “RaspberryPi @ Yeelink” –no-timestamp /home/pi/image.jpg

curl –request POST –data-binary @”/home/pi/image.jpg” –header “U-ApiKey: fill in your APIKEY here” –url http://api.yeelink.net/v1 .0/device/176/sensor/121/photos (replace with your own url here)

Add executable permissions to this script
chmod +x /home/pi/yeelink.sh
Now execute this command to see if the upload is successful and there is no /home/pi/yeelink.sh
If it is found that it is not running, please make sure that you have given the executable permission to the yeelink file, because many times, after installing the system, we will add a new account, and all information processing is handled by this user, not the pi user. Please save the yeelink.sh file to the correct user directory and give executable permission. Since I do monitoring, of course I don’t want to run this program every time, it is necessary to run the program automatically at startup: Run the crontab -e command and enter the following:
*/1 * * * * /home/pi/yeelink.sh

This is a middle picture. The frequency is not high. For thieves, it may have passed by. Therefore, it can be replaced with a smaller time, but the yeelink platform has restrictions on this. The time interval cannot be less than 10 seconds, otherwise Yeelink will not recognize it.

In this way, the picture monitoring is completed.
Now there is a more stable image bed space: Baidu Cloud, using the authorization function of Python, can be directly saved to Baidu cloud disk, and this is relatively private, unlike yeelink, its own sensors are public, only yeelink owns The sensors are not public.

The next step is to make a small family NAS to download movies and use it as a home video storage center.

The B-type Raspberry Pi I bought has a memory of 512M. If it runs a picture monitor with negligible CPU and memory usage. It is too wasteful, not in line with the purpose of DIY and no waste. Besides, the 20M optical fiber at home is not used during the day, so it is a waste of time to use these hours at night. It was a serious waste of the entanglement and “great ambition” when paying so much money to Telecom.

For a family with a smart DAHUA NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2,DH-NVR2108HS-8P-4KS2,DAHUA DH-NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2 Price who likes to watch movies and American TV series, the lag is unbearable, and being able to watch the latest episodes is also a minimum requirement. It is better to have a robot to help us when I go to work. Get the show ready. When I go home, I can see freshly released American dramas. The most important thing is that when I suddenly heard that a certain movie has been released in my work unit, and someone gave a seed, I can immediately arrange for him to download it.

Well, with the Raspberry Pi, isn’t this a piece of cake?

Is it not enough to install a torrent download software in the raspberry pi? , Combined with the mobile phone APP, for remote control, this is the prototype of an intelligent audio-visual system.
So I started searching for software. Many people are accustomed to using Thunderbolt to download, but many PT original disks do not support Thunderbolt download, but I can’t install multiple softwares. After all, this will affect the performance of the Raspberry Pi. Xunlei is offline with me. DAHUA NVR2216-I2,DAHUA NVR2108HS-4KS2,DAHUANVR2104HS-P-4KS2,DAHUA DH-NVR2216-I2,DAHUA DH-NVR2108HS-4KS2,DAHUA DH-NVR2104HS-P-4KS2,NVR2216-I2,NVR2108HS-4KS2,NVR2104HS-P-4KS2,DH-NVR2216-I2,DH-NVR2108HS-4KS2,DH-NVR2104HS-P-4KS2,NVR2216-I2 Price,NVR2108HS-4KS2 price,NVR2104HS-P-4KS2 price,DH-NVR2216-I2 price,DH-NVR2108HS-4KS2 price,DH-NVR2104HS-P-4KS2 price takes time to download the things you download from Xunlei offline to the local. The most important thing is that Xunlei offline needs the support of soft sister coins. If you have it, congratulations, then you are cool.
At this point Aria2 and transmission came into my sight.

Both software have a large user base, and both can be managed through mobile apps and software. The former’s web client function seems to be more powerful, and it can also support DAHUA NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2,DH-NVR2108HS-8P-4KS2,DAHUA DH-NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2 Price offline. If you are a local tyrant and have Xunlei members, Aria2 is the first choice.
Too bad I’m not a rich man. So I chose transmission.
I haven’t compromised my quality of life by choosing transmission, because transmission has fulfilled all my home theater dreams.
Since you want to do nas and download machines, there is another software that is necessary and that is samba. He was born to share. Regardless of Windows, Android, or other systems, you can access the video files on the Raspberry Pi through him. In a word, cross-platform stuff is cool!

Because of the cross-platform capability of samba, the external hard disk of the Raspberry Pi can be formatted without ntfs, because the monitoring system is also installed in front of it, and it is placed in a relatively hidden place. Of course, you can’t take down the hard disk every day, right? ? Let her be a quiet underground worker.
Well, a lot of nonsense has been said, let’s start:

First, format the hard drive into ext4 format, which can be formatted in Windows or Raspberry Pi.

Simple to Use
The brand new GUI layout can make the system effortless to work. The flat style and modular design offers a far more expert interface, which features obvious color strategies and visible icons that contribute to the person-pleasant expertise.

Don’t look at the outsole, blur, telephoto and so on every day in the photography circle. In fact, they are all functions that are not commonly used. In real life, mobile phones are enough. Originally, when mobile phone photography was still very common, the main function of the camera was to record. There is a famous saying that “if you are not good enough, it is because you are not close enough”. Later, the mobile phone clicked on the skill point of taking pictures. The portability of the camera was amazing, and it also came with a large screen and networking. It was very useful! The advantage of the camera to the mobile phone is the outsole and the lens, in the final analysis, it is the size advantage. The advantages of mobile phones are the DAHUA NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2,DH-NVR2108HS-8P-4KS2,DAHUA DH-NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2 Price process processor (40NM commonly used in cameras), the huge market and the technical strength of global participation. This is a gap that the camera product cannot bridge. To put it bluntly, it was the global system dominated by Apple and Google that blew up the island-wide system dominated by Sony and Canon. Relatively speaking, the price factor is secondary. So later Lei Dashan used the idea of ​​pian, DAHUA NVR2216-I2,DAHUA NVR2108HS-4KS2,DAHUANVR2104HS-P-4KS2,DAHUA DH-NVR2216-I2,DAHUA DH-NVR2108HS-4KS2,DAHUA DH-NVR2104HS-P-4KS2,NVR2216-I2,NVR2108HS-4KS2,NVR2104HS-P-4KS2,DH-NVR2216-I2,DH-NVR2108HS-4KS2,DH-NVR2104HS-P-4KS2,NVR2216-I2 Price,NVR2108HS-4KS2 price,NVR2104HS-P-4KS2 price,DH-NVR2216-I2 price,DH-NVR2108HS-4KS2 price,DH-NVR2104HS-P-4KS2 price, and huo to make a small ant camera, and it failed in a mess. The mobile phone has completely conquered the camera now, and the photography circle has also replaced the famous saying “photography is the art of light and shadow”. At this time, the camera is very embarrassing.

The reservation recording mode is relatively simple

First of all, you can’t set the date for the scheduled recording, you can only set the time and minutes to start the recording and the length of the recording, so you can only set the recording parameters within 24 hours before the recording starts, or set the recording parameters in advance. Start up within 24 hours.

Secondly, there are only two modes for reservation recording: “single reservation (reservation once, and it will expire after the recording is completed)” and “periodic reservation (reservation once, and recording according to the set period)”. At home, you can only record from the first game to the end of the second game. I won’t talk about the power consumption between games, but the recorded file is really a bit large. I experienced it once and recorded 7 hours and 40 minutes at best quality with a 48.6G file.

2. In the best quality mode, the video quality is slightly worse

For HDTV, the ER130 records at 1080i@50FPS. In this format, the best quality is a bit rate of 15Mbps. For more dynamic pictures, the mosaic can be clearly seen. We will talk about this in the next chapter.

3. So, I didn’t give up and started GC550

Because it actually looks quite clear on TV, I once suspected that it was actually the loss of picture quality caused by the low bit rate. So I didn’t give up and took aim at AVerMedia’s GC550. GC550 belongs to the series of gaming peripherals in the AVerMedia product series, capable of recording video up to 1080p@60FPS and 60Mbps. From the data point of view, the video quality will indeed be much higher than the ER130.

It can still be clearly seen (the comparison picture of the computer web version looks more obvious, the mobile version may be due to compression, the difference is not big), the high bit rate does provide a guarantee for the recording quality of the video. Although both devices use their own highest quality for recording, in the more dynamic pictures, the picture quality of the GC550 is still significantly better than that of the ER130, and the ER130 has obvious noise and mosaic; in relatively static pictures, the two The clarity of the picture is actually pretty much the same. As for the logo in Figure 3, although it is a static image, the clarity of the two screenshots is indeed much worse. Can an expert explain the reason? ?

There is another question here, should the recorded video really be saved as it is? I asked LD for instructions, LD gave me a blank look and said, although the quality is high, but a game for two hours, do you know how big it is? ? How do you want me to save it? ?

Hmm… that makes sense! For two hours, according to the highest quality, the GC550 will take about 42GB for a recording, which is indeed a bit excessive. If it is compressed to 5Mbps, will there be any difference between two different videos? try it.

From the point of view of video recording and collection, ER130 has timing function and can be operated completely offline, so it is more suitable for recording work that does not require very high picture quality, such as recording a TV program for review when you are not at home temporarily, or every time you need it. It is not very smart to set the time before the next game or record manually or something. Although it is not very smart, it has all the basic functions; and the GC550, although it cannot be reserved for recording, it is more suitable for recording content that requires high-quality preservation. The space for later video compression is also relatively large. I feel that the relationship between the two is like a card and a SLR, and they can still complement each other’s advantages.

But in terms of the two devices at hand, I’m actually still a little dissatisfied. The GC550 can record high-quality video, but there is no software that can reserve video recording, and there is no response to the email sent to AVerMedia (Shanghai) for help. As for the ER130, it is the problem of a single reservation recording setting, and DAHUA NVR2216-I2,DAHUA NVR2108HS-4KS2,DAHUANVR2104HS-P-4KS2,DAHUA DH-NVR2216-I2,DAHUA DH-NVR2108HS-4KS2,DAHUA DH-NVR2104HS-P-4KS2,NVR2216-I2,NVR2108HS-4KS2,NVR2104HS-P-4KS2,DH-NVR2216-I2,DH-NVR2108HS-4KS2,DH-NVR2104HS-P-4KS2,NVR2216-I2 Price,NVR2108HS-4KS2 price,NVR2104HS-P-4KS2 price,DH-NVR2216-I2 price,DH-NVR2108HS-4KS2 price,DH-NVR2104HS-P-4KS2 price is really powerless for complex recording situations.

In fact, my main purpose is to record a large number of live games, so the GC550 can be used in special circumstances, but the ER130 is still lacking for me. So there is another article in this article, that is, Shangmu has the AVerMedia ER310 sold in the mainland. After reading various introductions and demonstrations, this product is an artifact of TV recording. Its functions are much better than the ER130, but the slot point is still there. ER310 was purchased from Taiwan and is still on the way, so please wait for the unpacking~

Bind the mobile iPTV address to 192.168.50.9, [Source IP] to 192.168.50.9, [Destination IP] to all, [WAN Module] to select [Second WAN], after the application, the mobile iPTV can be under dual WAN normal use.
【About the setting of Dahua NVR】
After enabling the dual WAN dial-up of telecom and mobile, there was a problem that the Hikvision DVR was offline for no reason. It was checked that the two WANs were connected normally. After disconnecting the mobile broadband, the line was restored. It was suspected that it was caused by the double dialing. After the health IP is bound, it is 192.168.50.7, [source IP] is set to 192.168.50.7, [destination IP] is set to all, [WAN module] selects [preferred WAN], Hikvision no longer has the problem of being offline for no reason.

One is to learn the mobile phone, take the civilian route, use the sales to amortize the cost, and strive for a camera for everyone. The second is to take the high-end and professional route and cut small groups of leeks. People will complain about expensive cars, but not excavators. The main question is why the camera can’t take the first route. One is to learn from Apple’s own design and global procurement, which cannot be achieved with the strength of Canon, Sony and other factories. After all, there is a lack of management and software talents. The second is that human technology has an upper limit.

Router background – advanced settings – external network (WAN) – dual line. Turn on dual lines, specify the network cable interface of the preferred and second WAN, select “Load Balancing” for dual line mode, and the following ratio is set according to the bandwidth of your two broadbands (or what you think is appropriate). Enable routing rules: Yes. Press ➕ to add a rule: the source IP is the device IP (the device IP is best manually specified in the advanced settings-internal network LAN-DHCP server settings), the destination IP is input all (or a specific IP), and the WAN module selects the broadband that the device wants to go. . The above is the background setting of Asus. It is estimated that other brands are similar. It is quite simple. Different operators (My Mobile + Telecom), if you do not specify the broadband of the device, it may cause problems with the software networking. Generally, the software networking is fine. For the time being, it is found that the only thing that cannot run normally is the Alibaba Cloud Disk.

If the lens is to have image quality, it must be made that large. If it is large, it will not be portable. If it is not portable, no one will buy it, GG. Third, the technical threshold is not too high. The lens is not as difficult to manufacture as the chip. If the sales of the camera come up, the Japanese brand will definitely not be able to beat the Chinese brand, and finally it will be used as a wedding dress for others. So camera manufacturers chose the second route, which is to turn the camera into a tool and sell it to professionals. As for cumbersome, difficult to use, expensive, etc., that is a necessary threshold. Although the sales are low and ugly, there is still food to eat, so don’t think too much. The camera factory itself is also very numerous, and the energy invested in the camera is getting smaller and smaller. Olympus

Canon came from behind. Although the performance of the fuselage is not as good as that of Sony, it is still enough. The three heads of 11-22 (strong travel), 22 cakes, and 32 1.4 are all very good. Sigma 16 1.4, 30 1.4; Canon users have new options. Sony concentrates on the development of full-frame, and the cut-off is basically unchanged. The recommended lenses are only three sets of 50 1.8 and Sigma 1.4. The Fuji lens group is basically complete, and the fuselage is gradually upgraded. I only have the strongest blurring of the saliva: 56 1.2, and ignore the others. Aoba and Panasonic have basically not changed, but now the price of Xiaoyi 42.5 1.8 salted fish is 400, and the price/performance ratio is beyond the table. It is recommended that M43 users do not have a medium telephoto manpower.

Salted fish can’t understand it anymore. Many second-hand equipment is the same price as Taobao’s new Hong Kong goods, speechless. -Update: 1. A simple and rude sentence for Xiaobai who doesn’t want to study in depth: Go to the counter to see the prototype, and then buy the one you like best within your budget. The specific explanation is as follows: 1. As the old saying goes: You get what you pay for, don’t expect to spend 3,000 yuan to get the enjoyment of 5,000 yuan. Although there are differences between the equipment of the same level, they are basically in the same grade. , The starter kits of each company are similar. If you are satisfied with the kits, you can buy them according to your own preferences. If you really know the purpose of your camera, and you want to take photography as a hobby and invest time and energy for a long time, you need to study each lens group.

2. The difference in equipment is far less than the impact on the photo effect in the early stage and the later stage. The camera is not used to take pictures and count the hair. Taking pictures is a creation and an art. For example, brushes, you may need brushes of different specifications to achieve different effects, but if you don’t replace domestic brushes with foreign famous brands, your work will be able to advance by leaps and bounds. 2. Budget and use are the keys to purchasing a camera. There is no perfect machine. In order to maximize competition and profits, each factory has different positioning of each product, such as Fuji X-T10, X-A3, X-E2S The prices of the three products are similar, but each has advantages and disadvantages. To put it bluntly, it is not to make you happy. If you want to be happy, you can buy the flagship model. Many people plan to buy a camera. The original budget is 3-4 thousand, but after a round of research on the Internet, the budget is raised to 5-6 thousand… There is a famous saying in the camera circle: buy the most expensive camera you can buy, sorry I can’t I agree that the previous cameras were slow to update. A camera has been used for more than ten years. Now it is replaced every two years and three years.

The technology is changing with each passing day, and there is no need to overinvest.

Some people are too demanding and buy several lenses at once, but only one is used in the end; If you find that you don’t like your appetite, clear all the doors for replacement… So, my suggestion is: just buy an entry-level camera. If you are relatively financially able, then you have two options: one is to buyDAHUA NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2,DH-NVR2108HS-8P-4KS2,DAHUA DH-NVR2108HS-8P-4KS2,NVR2108HS-8P-4KS2 Price  an extra lens , to get completely different effects from the kit, such as blurring; the second is to buy a mid-end kit to get a better control and use experience.

After inserting the hard disk, run the sudo fdisk -l command directly, and you can see the hard disk device.
Where /dev/sda1 is the device number of the hard disk
sudo fdisk /dev/sdb1

If there is no partition, create a new one, use n, if there is a partition, delete all d.
Select n to create a new partition
#n add
#p expands to e;
The primary partition is p#1

Then #P sees the partition where sdb1 was created

#w save and exit
Before formatting, unmount the hard drive with the umount command
Then format it into ext4 format
#mkfs.ext4 -L usbdisk /dev/sdb1 Label format with usbdisk
Then load it once, mount /dev/sda1 L /media/usbdisk
The hard disk in ext4 format does not need to be automatically loaded every time after it is loaded once. Because the system will be loaded automatically, if you use the fstab to add a command to load, an error will occur, causing the system to fail to boot to a normal state (I don’t know the specific reason for this, this is the case when I tested it myself, and it may be the same as when I used the ntfs format before. settings are related).
reboot to restart the system,
Then change the user attribute combination of usbdisk directory sudo chown pi:root /media/usbdisk
Then the specific read and write permissions of the folder. sudo chmod -R 777 /media/usbdisk
Where -R is to recursively change the permissions of all subfolders to 777
I use a class10 SD card to test an ext4 formatted hard drive, and the copy speed can reach 6M+
The NTFS format is only a few hundred K, and the CPU usage is extremely high when downloading videos, up to 89%. After a long time, such as two days, it is easy to crash.
So this is the reason why I choose ext4 directly. If you want to use it frequently for file operations with the windows system, you should use NTFS format.
Of course, to use this format, you need to install ntfs-3g, and you need to set up to automatically mount the hard disk.
But I don’t recommend doing this. After all, there is still software for reading ext format files under Windows. Although it is not easy to operate directly, it can be replaced.
In summary, using ext4 is the perfect solution.
The hard drive is ready. Then start the software installation:

First install samba:
sudo apt-get install samba samba-common-bin
Then modify the configuration file: /etc/samba/smb.conf.
Because it is shared within the family, there is no need for security settings. Therefore, delete all the configuration and replace it with the following code: [global]
workgroup = WORKGROUP
netbios name = jiazhoulvke
server string = Linux Samba Server
security = share
[samba]
path = /media/usbdisk/
writable = yes
browseable = yes
guest ok = yes
After making changes, restart the samba service:
sudo /etc/init.d/samba restart
In this way, the smb is installed, and now we have a low-power NAS.

The next step is to install the BT download software: transmission

Not only does it support the mobile app, but even better it can be controlled via the web interface!
1) First install transmission :
sudo apt-get install transmission-daemon

2) Then create a download directory, one is the downloaded directory, the other is the unfinished directory, the specific directory is determined according to your situation:
mkdir -p /media/usbdisk/incomplete # for incomplete downloads
mkdir /media/usbdisk/complete # finished downloads

3) Also configure the permissions of the directory:
sudo usermod -a -G debian-transmission pi

Because the ext4 format is loaded by default, there will be no permissions, as long as you manually add permissions.
chgrp debian-transmission /media/usbdisk/incomplete
chgrp debian-transmission /media/usbdisk/complete
chmod 770 /media/usbdisk/incomplete
chmod 770 /media/usbdisk/complete

4) Modify the configuration file /etc/transmission-daemon/settings.json , which is a json format file with many configuration items, but focus on changing the following:
Download directory location:
“download-dir”: “/media/usbdisk/complete”,
unfinished download directory
“incomplete-dir”: ” /media/usbdisk/incomplete”,
Whitelist addresses to allow web access
“rpc-whitelist”: “192.168.1.*”,
This IP range depends on your router settings, you know.
If you need to control it with your mobile phone, and control it when you are in the unit or in the field, then you need to change the following settings:
“rpc-whitelist-enabled”: false,
If you want to change the username and password:
Change the settings a bit:
“rpc-password”: “Password” You can directly write the password here, and it will be automatically encrypted after restarting
“rpc-username”: “new username”

5) Finally, restart transmission after configuration. Note that the following two commands are executed in order. The configuration will not be saved if restarted alone:

sudo service transmission-daemon reload
sudo service transmission-daemon restart
It’s good now, access the IP and port 9091 in the browser: for example: http://192.168.1.3:9091/ . Enter the user name and password when accessing, the default is: transmission.
You now have an independent torrent download server! The interface is fully functional, and you can set speed limits and other settings.
For more information on transmission configuration, please refer to: EditConfigFiles .
How to modify transmission username and password:
1) Stop the service first: sudo service transmission-daemon stop
2) Start the service again: sudo service transmission-daemon start . At startup transmission will automatically encrypt the new password.
In addition, transmission listens on port 51413 by default, it is best to do a port forwarding on the router and transfer this port to its IP address.
If you want to use a mobile phone to manage the transmission, you also need a router that supports the peanut shell service, log in to the peanut shell and set up port forwarding.
