Replacing it yourself will not be a problem. Another common problem is the lack of images and control menus. At the same time, the equipment is operational and accepts requests. The cause of the problem is an interruption in the video output circuit. To restore the operation of the mechanism, it is necessary to replace the corresponding board. If the video device periodically restarts or shuts down automatically, there may be a hardware failure. In this case, the chips may overheat. To troubleshoot, you need to eliminate the cause of overheating. A common problem in the operation of the system is a discrepancy between the firmware of the mechanism and the installed software. The camera needs to be reinstalled in a different location or the software needs to be updated. It is better to update the factory firmware of the device to a more modern version with the help of specialists.
If the module burned out, we change it entirely, if the infrared IR-Cut filter, lens or IR LED backlight, they can also be replaced. Do-it-yourself repair will consist in finding and replacing a faulty element.
Info
If there are no reset buttons, you can try to reset it programmatically, using the settings via the web interface or the ResetTool utility. Happy repair!
Video playback speed is 3x or less at best. Viewing records, for example, for a week is not a very quick task.
A black box is bad, uninteresting, unsportsmanlike. After some time, I received an order for the equipment of another point. After weighing all the pros and cons, I offered to make video surveillance using the system unit and the motherboard of the ITX form factor and a web camera. Consent to this was easily obtained, as in this version, the cost of equipment for video surveillance is almost half as much as with the "standard" version with a video recorder.
No need for a separate power supply for the camera and microphone, less wires. However, there is a drawback - a short video camera wire - usually no more than 1.5 m.
But you can either lengthen it (although this can adversely affect the performance of the camera, since usb can be capricious), or put the system unit next to the camera, because. it is small when taken motherboard ITX (and as a bonus, it is quiet, quieter than many DVRs). WITH system unit everything is clear, however, when choosing a camera, questions arose, the answers to which I could not really find either in the Russian-speaking or in the “bourgeois” segment of the Internet, although maybe I was just looking badly, but at that moment I had to turn on my head.
So, the main problem of using a webcam for video surveillance is the lack of information from the manufacturer about the viewing angle of the camera. Without this, it is impossible to guarantee the customer that everything that he needs will be visible in the recording.
Equipment diagnostics. Let's say you have a video surveillance system, and one out of four cameras stopped showing. First, you need to check if power is being supplied.
Attention
Because most often it is not the camcorder itself that fails, but its power supply. Almost all modern devices have IR illumination around the lens.
Also, the voltage can be checked with a multimeter (tester) at the output of the power supply, most video cameras consume 12 volts. Secondly, we check the channel on the registrar (for AHD/TVI/Analog).
We connect a faulty camera to another channel of the recorder, there are cases of burnout of one of the channels - the repair of the recorder will be required.
When installing PTZ cameras, it must be remembered that their failure is due to a number of technical reasons:
Software problems can be fixed by updating the firmware version, and mechanical problems by replacing individual parts. Why is periodic technical inspection of the video surveillance system necessary? Systematic maintenance of the video surveillance system is necessary for the smooth operation of the entire complex. Performing qualified maintenance is entrusted to specialized firms. For this, an agreement is concluded between the parties. It must indicate the frequency of maintenance work.
From the range of webcams offered by local suppliers using the brute force method, I found one - the only camera, for which the sensor size was specified: 1/3 "CMOS, (Canyon CNR-WCAM420). From the lenses offered by the local supplier, I chose the one that provided the required view for the specified matrix (DW2162 160 degrees for a given 1/3 matrix), with an M12 thread that should approximately fit the camera.
The first attempt to replace the camera lens with an M12 lens failed miserably. The camera thread turned out to be half a millimeter smaller in diameter than the lens. After searching the Internet for ways to solve this problem, studying bourgeois instructions like “buy special miracle crap in a special online store, attach it and voila (for example www.instructables.com/id/Wide-angle-web-cam/) I already was almost ready to do something similar.
On the video - repair of a video surveillance camera: Causes of a malfunction of a video surveillance system The reasons for the failure of video surveillance systems can be varied:
Select a day using the "Select a date" panel (number 1) by clicking on it with the left mouse button. There are two ways to select the desired time period for viewing and downloading:
However, during another “meditation” on a camera with a lens, I remembered one old anecdote that suggested a solution to the problem in a truly national manner without the need to buy anything unnecessary: The Americans stole the blueprints of a fighter from the Russians. Collected - a steam locomotive. Dismantled, assembled - a locomotive! What to do, they stole a Russian specialist. The specialist takes the drawing, looks, looks and says: “In the same place at the bottom in small print: after assembly, process it with a file.” I took a file in my hands, took a freshly bought lens, and after ten minutes the lens began to freely enter where it was supposed to serve faithfully. In order not to accidentally damage the threads in the camera, I grinded off the threads on the lens a little more than necessary, and then wrapped it with electrical tape - another material that a rare national knee-length craft can do without.
How to determine the cause of the inoperability of the camcorder? In order to determine why the CCTV cameras caused the failure of the entire complex, it is necessary to diagnose them. To do this, check the power supply and its magnitude.
To check if the video equipment is working, you can connect the device to another test system. If the system is equipped with an analog video camera, then it must be connected to a mobile tester. In this case, the video signal will be checked. If IP video surveillance cameras are installed in the complex, then testing will be carried out using personal computer. In this case, specialized software must be installed on the computer, and the camera must be displayed on the local network.
Camera failures on the Iphone are due to an error in software phone, or due to damage or any boards that convert and conduct signals. On the screen itself, there may be chips, dirt, which need to be restored by the master. Sometimes the so-called. loop - the entire upper complex of the phone. In addition to the camera, you also have to replace the speaker.
The front camera (or rear) is used for video communication via Skype, WhatsApp, Viber. Use it to take selfies. Damage to it is less common than the back. But the renovation takes longer. It is necessary to remove the case, remove the display, protective boards separating the screen and the camera. Next, look for the cause of the malfunction.
iPhone cameras are considered among the best among other competing smartphones. This is due to the high quality lens, wide aperture. Repair of the rear camera is needed most often. This is especially due to the waterproof models of the iPhone 7, 8, and X. Often the smartphone works, but a cloudy cloud appears on the camera after water gets in. Frequent and banal breaking of the lens, failure of the flash, spots and much more.
Not to mention system failures in the OS. This is manifested by a black screen at the moment the camera icon is pressed, a constant, non-disappearing download process, not saving recorded videos and photos to memory, etc. This can confuse the user, consider the phone to be defective, especially if it is bought from hand. We solve these problems too.
About everyone possible problems we will inform you after the diagnosis, and also offer all solutions. But the main thing is that there is always an opportunity to fix the camera. We work with the most difficult cases. Depending on the type of breakdown - for each there is its own approach to solving the problem.

Is it possible to improve the front or rear camera in a samsung galaxy, lenovo, meizu m3 note 3 pro, xiaomi redmi 4x, lg k10 2017 phone running on android 6.0.
These are the questions I get asked most often. If your smartphone or tablet has a bad camera, then something can be improved.
In general, now the camera function is being added to many devices, ranging from mobile phones.
Just to get good image quality, you need a SLR camera, although you can get really good results in idle time if you apply the right settings.
To begin with, it is worth explaining the relationship between sensor size and image quality and dispelling the myth about the number of megapixels, which quite often is not a determining factor in quality when shooting.
It happens that a phone camera with 2 megapixels makes a much higher quality than a matrix with 12 megapixels.
Firstly, the more megapixels, the bigger the picture you get and the better the lens, the better the image quality will be.
Another issue is the camera control software that comes from the manufacturer and manages it all.
You can "enhance" the software to get best quality Images. Get acquainted with programs that improve the quality of the built-in camera, .
To improve the quality of photographs taken with mobile phone, several important issues need to be kept in mind.
Lighting - try to keep the objects well lit - the weaker the lighting, the more "noise" will be visible in the picture, and if your phone is equipped with an LED flash, it's good to turn it on.
Although the built-in flash is not able to illuminate the entire subject, it can always help a little (LED flashes are more marketing ploy, not a strong flash lamp).
Contrast is a parameter to consider when photographing indoors where the lighting is artificial - thanks to it you will be able to preserve natural colors.
Digital Zoom - Definitely avoid using this option as nothing ruins image quality more than digital zoom.
Image Stabilization - Some phones offer digital image stabilization, which is not to be trusted unconditionally.
Auto focus - should be used when there is a problem with sharpness when trying to capture objects.
ISO - Noise in images is often the result of excessive use of ISO settings that add artificial light from low light- Higher ISO values can take clearer pictures in poor lighting conditions.
I am often asked - how to improve the camera with engineering menu? I’ll tell you how to enter it, but don’t count on super improvement, and not every smartphone will be able to launch it.
NOTE: if your smartphone or tablet runs on a Qualcomm chipset, then there may not be an engineering menu, but on those that use Mediatek processor will be for sure.
To open the engineering menu, enter the command: *#*#3646633#*#*. If this code does not work, try another one: *#*#4636#*#* or *#15963#*.
NOTE: on Xiaomi smartphone you need to click on the “Kernel Version” parameter several times in a row.
Using the engineering menu, you can make some changes and check the sensors and perform component testing.
If the code did not work, you can try using the MobileUncle Tools or MTK Engineering applications - you can download it on the play market.
After logging in, you should be interested in the "Camera" option - setting various parameters.
After the transition, the settings will open.
Engineering menu is preferred for experienced users and it must be used very carefully so as not to do tragic "miracles".
If you already have a filmed video, but of poor quality, then it can also be improved using computer programs.
Movavi Program video editor is a powerful and at the same time simple video editor. When using it, the following tools will become available to you: cropping video edges, rotations, adding audio, effects, filters and others
vReveal is a great assistant if you like to shoot videos with your phone. Then, most likely you get a video far from ideal.
vReveal has quality enhancement technology to improve the quality of video files and clips.
Video Enhancer - This program is able to increase video resolutions. You can dramatically improve the quality of your photos or videos with Video Super Resolution technology.
With the help of frame detail technology, you can increase the resolution to the HD standard.
NOTE: all programs have a drawback - they are paid, and I could not find worthy free analogues. Good luck.
Many users of smartphones running on operating system Android users are often disappointed in the quality of photos taken with the camera of their device, because in online reviews and other owners of similar devices, photos turned out much better. What could be the causes of this problem and how to improve the camera on Android?
Let's take a closer look at each of them.
1 Camera failure. Multi-colored stripes in the photo, spots, strong blurring are, with a high probability, a marriage of the camera itself. That happens. And if your smartphone is still under warranty, you should take it to the store for an exchange or take it to a service center.
2 Errors in the program "Camera". Firmware manufacturers sometimes make “blunders” by releasing unfinished software for sale. Typical symptoms of such a “hack” are: inverted colors in the photo, an inverted image, or the camera completely fails to start.
What to do in this case? Fortunately, there are many programs that are analogous to a standard camera, and if you wish, you can install any of them on your smartphone, or even all at once.
HD Camera
Great app with lots of manual settings, which allows you to adjust the image size (number of megapixels) and image compression quality, as well as white balance, and select different shooting scenes. As a bonus, there is a tilt position of the smartphone, which will allow you to take photos without filling up the horizon and a QR code scanner.

DSLR Camera
An excellent application with many settings that will make you feel like a real photographer. Among useful features it is worth noting the choice of ISO, a visual histogram, a grid for easy frame building, tracking focus, white balance and much more.

3 Incorrect camera settings. It would seem a trifle, but many do not know that despite the declared presence in the cell of five, eight, thirteen, etc. megapixels, this parameter can be set arbitrarily. And not always when buying a device, it is set to the maximum. Therefore, first of all, you should go to the settings of your camera and see what mode is set.
The higher the resolution of the image, the more likely it is that the photo will look better on a computer or TV screen. Also try to adjust the white balance (WB), it is possible that it gives unrealistic colors.
It is very important to set up the camera on your smartphone and enjoy high-quality pictures. And by the way, an important detail is the ability to turn off the sound when shooting. This greatly simplifies life in rooms where silence is required (for example: a library, a lecture room, etc.). To learn how to mute your camera, see the article:
Good pictures for you!
Articles and Lifehacks
Dissatisfaction with certain characteristics mobile device leads to the fact that users begin to wonder: is it possible to change something?
Let's talk about whether it is permissible to replace the camera in the phone on your own, and how service centers treat this.
Perhaps, this device was at one time not the most successful attempt by the manufacturer to release a “premium” device.
Of the truly "premium" characteristics, we can only highlight the use of an amorphous liquid metal alloy, which is twice as strong as titanium, and the presence of two active radio modules that allow you to install two SIM cards (and quickly drain the battery).
Other than that, it's just an ordinary phone.
