Fair, not overpriced or understated. There should be prices on the Service website. Necessarily! without "asterisks", it is clear and detailed, where it is technically possible - the most accurate, final.
With the availability of spare parts, up to 85% of complex repairs can be completed in 1-2 days. Modular repairs take much less time. The website lists the approximate duration of any repairs.
Warranty and liability
Any repairs must be guaranteed. Everything is described on the website and in the documents. The guarantee is self-confidence and respect for you. A 3-6 month warranty is good and sufficient. It is needed to check quality and hidden defects that cannot be detected immediately. You see honest and realistic terms (not 3 years), you can be sure that they will help you.
Half of the success in Apple repair is the quality and reliability of spare parts, so a good service works with suppliers directly, there are always several reliable channels and your own warehouse with proven spare parts of current models so that you do not have to waste extra time.
Free diagnostics
This is very important and has already become a good form for the service center. Diagnostics is the most difficult and important part of the repair, but you shouldn't pay a dime for it, even if you don't repair the device as a result.
Repair in service and delivery
A good service appreciates your time, which is why it offers free shipping. And for the same reason, repairs are carried out only in the workshop of the service center: correctly and according to technology, it can only be done at a prepared place.
Convenient schedule
If the Service works for you, and not for itself, then it is always open! absolutely. The schedule should be convenient so that you can be in time before and after work. Good service works both on weekends and on holidays. We are waiting for you and working on your devices every day: 9:00 - 21:00
The reputation of professionals consists of several points
Age and experience of the company
Reliable and experienced service has been known for a long time.
If a company has been on the market for many years, and it has managed to establish itself as an expert, people turn to it, write about it, recommend it. We know what we are talking about, since 98% of incoming devices in the SC are being restored.
We are trusted and passed on by other service centers for difficult cases.
How many masters by directions
If you are always waiting for several engineers for each type of equipment, you can be sure:
1. there will be no queue (or it will be minimal) - your device will be taken over immediately.
2. You are handing over your Macbook to a Mac repair expert. He knows all the secrets of these devices
Technical literacy
If you ask a question, a specialist must answer it as accurately as possible.
So that you have an idea of what exactly you need.
They will try to solve the problem. In most cases, the description tells you what happened and how to fix the problem.
Many users of smartphones running on the Android operating system are often disappointed in the quality of photographs taken with the camera of their device, because in Internet reviews and other owners of similar devices, the photos turned out much better. What could be the causes of this problem and how to improve the camera on Android?
Some of the possible reasons:
- Marriage of the camera;
- Errors in the "Camera" program;
- Incorrect camera settings.
Let's take a closer look at each of them.
1 Marriage of the camera. Multi-colored stripes in the photo, spots, strong blurring - this is, with a high probability, a marriage of the camera itself. That happens. And if your smartphone is still under warranty, it should be taken to the store for exchange or returned to the service center.
2 Errors in the "Camera" program. Firmware manufacturers sometimes make "bloopers" by launching unfinished software for sale. Typical symptoms of such “hack-work” are: inverted colors in the photo, inverted image or camera refusal to start at all.
What to do in this case? Fortunately, there are many programs analogous to a standard camera, and if you wish, you can install any of them on your smartphone, or even all at once.
Applications - replacing the standard "Camera"
HD Camera
An excellent application, with a huge number of manual settings, thanks to which you can adjust the image size (number of megapixels) and the compression quality of the photo, as well as the white balance and choose different shooting scenes. As a bonus, there is a tilt position of the smartphone, which will allow you to take photos without blocking 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 the useful functions, it is worth noting the choice of ISO, a visual histogram, a grid for easy frame construction, 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 it is not always set to maximum when buying a device. Therefore, first of all, you should go to the settings of your camera and see which mode is set.
The higher the resolution of the picture, the more likely it is that the picture will look better on a computer or TV screen. Also try adjusting the white balance (WB), it may be 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 mute 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 to you!
Articles and Life Hacks
Dissatisfaction with certain characteristics of a mobile device leads to the fact that users begin to ask the question: can something be changed?
Let's talk about whether it is permissible to replace the camera in the phone on our own, and how service centers relate to this.
Why do we need to change the camera and is it possible
- If the camera of our mobile device has begun to shoot poorly, you can always replace it with a working one by contacting the service center.
- Please note, however, that we will not be able to replace the camera with a different type due to differences in software and dimensions. In addition, it is worth taking into account the fact that this procedure is not always reasonable and expedient.
- Often the cost of repairs is slightly less than the cost of a new phone
- Let's add that the number of pixels has long been no longer the most important parameter in modern technology. On the contrary, an increase in their number simultaneously with the preservation of the small size of the matrix negatively affects the quality of the shooting.
- In other words, the sensor and lens are much more important criteria. Many modern smartphones have a better camera than an inexpensive soap dish.
- If our mobile device was produced by a good manufacturer, you can always contact the service center with a question of replacing the camera. However, if the device is Chinese, hardly anyone will agree to change the camera on it.
Instructions for replacing the camera module
For each mobile device model, there is an individual instruction on how to replace the camera module. We will try to replace it with the example of the GT-S9402 Ego phone from Samsung.
Perhaps, this device was at one time not the most successful attempt by the manufacturer to release a "premium" device.
Of the really "premium" characteristics, we can only highlight the use of 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).
Otherwise, this is the most ordinary phone.
- We begin to disassemble the Samsung Ego. Remove the back panel and battery. Remove the side inserts from both sides with a metal spatula.
- Unscrew the screws securing the side panels and remove them. Unscrew the four screws from the back of the phone. Using a screwdriver, remove the top metal cover, and then remove the plastic insert. Next, unscrew the screws.
- We turn the device over and remove the front panel, after which - the keyboard. Unscrew the two screws from the front of the phone.
- Remove the bottom plate with a metal spatula. Then remove the back panel with your fingers.
- Disconnect the flash cable. There is another screw under it, which we unscrew. Next, remove the antenna unit and remove the protective metal plate.
- Using a screwdriver, disconnect the display connector and the keyboard connector. We pry on the motherboard and remove it. Disconnect the camera button and polyphonic module. Disconnect the flash and remove the polyphonic module. We snap off the module with the camera.
- We snap the new module onto the system board. Then we install the polyphonic module. We snap the flash and install the motherboard on the middle part. We put back the connector of the display and keyboard. Install the camera button.
Replacing it yourself will not be a problem. Another common problem is the lack of display and control menus. At the same time, the equipment is operational and accepts requests. The problem is caused by an interruption in the video output circuit. To restore the mechanism, it is necessary to replace the corresponding board. If the video device automatically reboots or shuts down periodically, a hardware failure is possible. In this case, the microcircuits may overheat. To troubleshoot the problem, you must eliminate the cause of the overheating. A common problem in the operation of the system is the inconsistency of the firmware of the mechanism with the installed software. The camera needs to be reinstalled in a different location or the software must 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 burns out, we replace it entirely, if the infrared IR-Cut filter, lens or IR LED illumination, they can also be replaced. Do-it-yourself repair will consist in finding and replacing a faulty item.
Nowadays, finding them in retail is not easy. The task will be greatly facilitated if there is a "donor". If the digital ip camera stopped loading, try to "reset" it.
On some models there is a reset button, which can be pressed with a pin / pin, or when the camera is turned on, two unused contacts on the power block are closed. Also came across models on which reset is displayed on the tail.
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 renovation!
CCTV systems
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 a while, I received an order for the equipment of one more point. After weighing all the pros and cons, he offered to make video surveillance using a system unit and a motherboard of the ITX form factor and a web camera. Consent to this was easily obtained, since in this version, the cost of video surveillance equipment is almost half as much as in the “standard” version with a video recorder.
No need for separate power supply for camera and microphone, less wires. However, there is a drawback - a short video camera wire - usually no more than 1.5 m.
CCTV camera diagnostics and repair
But it can either be lengthened (although this can have a detrimental effect on the performance of the camera, since usb can be capricious), or put the system unit next to the camera, tk. it is small if you take an ITX motherboard (and as a bonus, it is quiet, quieter than many DVRs). Everything is clear with the system unit, 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 camera's viewing angle. Without this, it is impossible to guarantee the customer that everything that he needs will be visible in the record.

Equipment diagnostics. Let's say you have a video surveillance system, and one camera out of four stops showing. First, you need to check if power is being supplied.
Attention
Because most often it is not the video camera itself that fails, but its power supply. Almost all modern devices have IR illumination located around the lens.
We cover the light sensor or the front panel of the camera with our hand so as to exclude the ingress of light. Built-in IR illumination, should light up in red, you can see it through your fingers.
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 recorder (for AHD / TVI / Analog).
We connect the faulty camera to another channel of the recorder, there are cases of burnout of one of the channels - the DVR will need to be repaired.
DIY CCTV camera repair: causes of breakdowns and their elimination
When installing PTZ cameras, remember that their malfunction is caused by a number of technical reasons:
- Rotary gear wear;
- Contamination of the control sensor;
- The line appearance program has failed.
Software problems can be resolved by updating the firmware version, and mechanical problems by replacing individual parts. Why is a periodic technical inspection of a video surveillance system necessary? Systematic maintenance of the video surveillance system is necessary for the smooth operation of the entire complex. Qualified maintenance is the responsibility of specialized firms. For this, an agreement is concluded between the parties. It must indicate the frequency of maintenance work.
From the range of web cameras offered by local suppliers by brute-force characteristics, I found one - the only camera for which the matrix 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 a camera lens with an M12-threaded lens failed disgracefully. The camera's thread turned out to be half a millimeter smaller in diameter than the lens. After searching on the Internet for ways to solve this problem, studying bourgeois instructions like “buy a 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.
- Surveillance method (covert or open video surveillance);
- Observation corner (swivel and non-swivel);
- Appearance (standard and domed);
- Method of information transmission (wired, wireless, IP cameras).
The video shows the repair of a video surveillance camera: Causes of a malfunction of a video surveillance system The reasons for a failure of video surveillance systems can be varied:
- Untimely maintenance of equipment or its absence;
- Making mistakes when designing a control line;
- Poor quality installation work;
- Violation of the rules for installing surveillance cameras and other components of the system;
- The operation of the surveillance camera for a long time to failure (development of the envisaged working resource);
- The impact of external factors, incl.
Is it possible to change CCTV cameras
Select a day using the "Select 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:
- A scale for selecting a time range is shown under number 2 in the figure. A purple section on the scale marks a video recording interval of 3 hours. If you move the cursor over this section, press and hold the left mouse button, and then move the mouse left or right, the viewing time interval will shift by earlier (if you move to the left) or later (if you move to the right) period of time.
- The second way is to specify the boundaries of the desired time period manually using the text fields marked with numbers 3 and 4 in the figure above. In the field under number 3, enter the start date of the video clip.
How to change the IP address of a CCTV camera
However, during another "meditation" over a camera with a lens, I remembered an old anecdote that suggested a solution to the problem in a truly national manner without having to buy something unnecessary: the Americans stole the plans of a fighter jet from the Russians. Assembled - a steam locomotive. Disassembled, assembled - a steam locomotive! What to do, they stole a Russian specialist. The specialist takes the drawing, looks, looks and says: "In the same place below in small print: after assembly, process it with a file." I took the file in my hands, took the 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 thread in the camera, I grinded off the thread on the lens a little more than necessary, and then wrapped it with electrical tape - another material that a rare national knee-work can do without.
- Manufacturing defects.
How to determine the reason for the inoperability of the video camera? In order to determine why the CCTV cameras caused the failure of the whole complex, it is necessary to diagnose them. To do this, you need to check the power supply and its value.
To test the functionality of the video equipment, 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 feed will be checked. If IP CCTV cameras are installed in the complex, then testing will be carried out using a personal computer. In this case, specialized software must be installed on the computer, and the camera must be displayed on the local network.
You no longer need to answer the question in the title. After all, millions of people go around the world who, after buying a new smartphone, throw an old digital camera into a corner, where it collects dust and waits for the moment when someone remembers it and displays it “as an exhibit in a museum”.
Kyocera Visual Phone VP-210 - that was the name the world's first digital camera phone... It went on sale in May 1999 in Japan and was equipped with a front camera with a resolution of 0.1 MP, through which it was possible to make video calls at an incredible speed of 2 frames / sec.
Now this specification sounds ridiculous, but it was with the VP-210 that began mobile revolution in the world of photography, and it soon became clear that everyone wants to have a camera on their phone.
Another revolutionary decision that had a huge impact on how much and how we photograph with our phones was released in 2007, when the world was introduced to the first iPhone.
The iPhone's 2-megapixel camera did not make any technical revolution - it is worth remembering at least that it was not possible to record video, for which it was often ridiculed. But the combination of good image quality, an intuitive interface, a large screen (a 3.5-inch display was considered large at the time) and easy access to fast image processing led people to use their smartphone cameras more often.
Moreover, thanks to modern smartphones, which began with the first iPhone, and the inextricably linked growth of the values of online media, share photos with a friend it has become easier, more enjoyable and has taken an important place in the schedule of many people. Shooting has become something natural. What everyone can and wants to do at any time and situation.
The first two years after the introduction of the first iPhone and the start of the smartphone boom, there were still a couple of fertile moments for the sale of standard compact cameras, but already in 2010 they reached their peak, and in 2011 the iPhone 4 became the most popular camera used by users of the popular service Flickr.
Today 8 of the 10 most popular cameras on this site are different iPhone models and none of the major camera manufacturers have any doubts that attempts to compete with smartphones make no sense, and the market for budget compact cameras is running out, and it is difficult to make money on it.
True, the world of mobile photography is dominated by pictures of cats, self-portraits and photographs of food, but the art of photography does not end there. Professional photographer Chase Jarvis published a book in 2009 called The best camera is the one that "s with you, i.e The best camera is the one you have with you. and it's hard to disagree with this name. In recent years, there have been many truly valuable photographs that we can only observe due to the fact that every modern smartphone has a camera.
Manufacturers see the needs of demanding and ambitious smartphone users and try to meet them. For example, the software is optimized for new, additional functions: a powerful manual mode, saving photos in RAW format, which allows you to "squeeze" everything out of the camera's matrix. The market for additional devices such as lenses for smartphones and photographic modules is also developing.
However, while smartphones satisfy most of the needs of a person who needs quick access to a camera, more and more often their functionality is run up against fundamental technical limitations that will be difficult to jump over.
The small size of the matrix remains a problem, which is exacerbated by the demand for thin smartphones. The lack of true scale is also often troubling, because fixed focal length lenses predominate in mobile devices and will remain so until some kind of revolution occurs in the world of optics.
The smartphone will fail to achieve many effects. In short, physics cannot be fooled and big, as before, maybe more - this is invariable. For this, what has changed is that this "big" and the functions it offers have become available to a larger circle of people.
Therefore, in recent years, the premium compact market has been developing very dynamically (for example, the Sony RX10 and RX100 series) - now, if someone decides to buy a camera, they are ready to spend a little more for these purposes, but in exchange they want to get a significant improvement in image quality and functionality.
Photo source: Janitors / CC BY What's next? It seems that for now, most companies have stopped "pixel hunting" and have accepted 12 megapixels as the sweet spot for smartphones. It just turned out in practice that further increasing the resolution and the associated decrease in the sensor pixel creates more problems than benefits.
However, everyone wants to somehow stand out from the competition and show that the cameras in their devices are "special". In the year just ended, many companies decided that the best way would be to add a second camera, although the understanding of what a second camera should do varies greatly.
Photo source: iphonedigital / CC BY-SA In the LG G5, the second camera has a wide-angle lens that provides a much wider field of view and a very interesting fisheye effect. On iPhone 7 Plus, the second lens has a longer focal length and allows you to artificially blur the background. In Huawei Mate 9, the second matrix is black and white, has a higher resolution and helps in the fight against noise.
Which of these solutions is better? It is difficult to say, because each of them has its own set of advantages and disadvantages. Also, my glass melted from the tubes of old monitors tells me that this trend will not bring much change to the camera market and will have trouble reaching the minds of gray smartphone users. Because the "power" of smartphones is the ability to take photos quickly, easily and fun, and the second camera and the associated functionality introduce additional, not necessarily useful, complications.
