Today, on the roads of our country, an increasing number of cars with DVRs appear. This has already become not just an additional gadget, but also a necessity. A car itself is a DVR – this is a device that is designed to video recording of everything that happens in the viewing sector of its camera. It works in motion and when the car is just in the parking lot. Also, the DVR records the sound and speech information of what is happening in the car interior. These devices became necessary mainly because of the ability to prove their case in controversial situations on the road. And more than once saved their owners from slander in cases of accident. But there are countries in which not all citizens are allowed to use such funds. So in some countries, the DVR is recognized as a means that monitors people and violates their rights to the inviolability of private property and interference in personal life. Therefore, their use is allowed only to certain state structures that have legitimate grounds for their use and use. Every day, the development of technological tools further and further, as a result of which new operating systems appear, on the basis of which DVRs are also made. The devices themselves are divided into portable and multi -channel. But those that have additional memory cards are more popular in our country, which allows you to constantly write down around. To date, the most common are DVRs based on iOS and Android. But if you have a smartphone, then you can find an application that will allow you to turn your phone into a DVR. And now more about autonomous and multi -channel DVRs. Autonomous have gained popularity due to low price and good quality. They have a direct purpose and nothing more. That is, a camera for filming and a memory card slot. They are also very easy to install and do not require additional energy sources. As for the multi -channel, they are represented by a separate recording block to which all kinds of sensors and separately displayed cameras are connected. You can bring up to 4 cameras to the main block. But the biggest drawback of such DVRs is their price and complexity of installation. The price of such a device starts at 1 thousand dollars.
