A video recorder is a necessary attribute of any modern car. It greatly facilitates the analysis of any controversial situations that may arise on the road. A video recorder can help prove innocence in an accident or help in a dispute with an inspector.
One of the most important parameters when choosing a DVR is the way it is mounted. The more reliable it is, the less chances that the device will come off the glass at a crucial moment. In conventional models, two mounting methods are used: on a suction cup and on a double tape. The suction cup is less reliable, because with changes in temperature and humidity, it can easily fall off and over time the fastening weakens.
In addition to the mounting method, you should pay attention to the optical part of the DVR. It must have a wide enough viewing angle, from 90 to 140 degrees, to capture several lanes in front of the car at once. It is desirable that the resolution of the recorded video be as high as possible, this is one of the most important characteristics affecting the picture quality. It is best if the recording will be in HD 1280x720 format.
You also need to pay attention to the recording frequency. It should be no lower than 25 fps. at the nominal resolution of the device. It is very convenient when the DVR has several recording speed modes, i.e. in the parking lot, he shoots, for example, 10k / sec., and in motion - 25k / sec. This can significantly save space on the memory card.
Another characteristic of the DVR is the maximum amount of memory card that it can support. The higher the value, the better. The video format is also very important. This is usually MPEG4 or H.264. The last one is preferable, since each frame in this format takes up 2 times less space. In addition, it is necessary to choose a DVR with a large matrix size. Good HD fixtures usually have 1/2 or 1/1.8 inches.
A very important characteristic that you should pay attention to when choosing a DVR is the climatic version. In the conditions of the Russian winter, it is necessary that the device can withstand a drop in temperature to -30, and preferably to -40 degrees.
It is also desirable that the video recorder has the following additional functions: - built-in monitor;
- automatic start / stop of video recording when starting / stopping the engine;
- fixing time, date;
- sound recording.
More expensive models can be equipped with a GPS receiver that determines the coordinates of the car via satellite, as well as a night view mode with IR illumination. GPS allows you to view the route of the vehicle on a map.
Only a well-chosen device will be able to provide high-quality video recording, which can really become evidence in a disputable situation. Therefore, it is better not to save on the DVR, because a cheap device is just a pointless purchase that can be very expensive in the future.
