DVR: Features of choice

The DVR appeared on the domestic market not so long ago. However, almost immediately managed to gain great popularity among motorists. Such a device tirelessly fixes everything that happens on the road and can help the driver in a hopeless situation. For example, a DVR can help prove the guilt or innocence of the driver during an accident or to attest to any illegal actions by the traffic police inspectors. Materials received in this way can be used in the trial. Today there is a large selection of models of DVRs that differ not only in their cost, design, manufacturer’s trademark, but also technical capabilities. It is on them that you should pay attention to, wanting to buy a DVR. One of the criteria for the right choice is the method of attaching the device. Most of them are attached with adhesive tape or on a suction. Both of these fastening methods are good and quite reliable. However, the adhesive tape should be glued a maximum of 1-2 times. Otherwise, its adhesive properties are quickly lost, which can not be said about the suction cup. Another important point is the angle of viewing of the camera, which should be at least 110-140 degrees. The DVR with a lower indicator will not allow, to properly evaluate the situation on the road, since it does not capture the oncoming lane. And with a larger angle of view - there will be a low quality of the picture. Among the technical parameters, video resolution is very important. Experts claim that it should not be lower than the standard parameter of 640x480. The number of cameras is another important criterion for choosing a video recorder. Most of them, with the exception of the cheapest models, have not one, but several cameras at once, which allow you to fix everything that is happening, both inside the car and outside, without missing more than one detail. Naturally, the more cameras, the more expensive such a device. Practically, all DVRs are equipped with an audio recording function. Moreover, some of them have two microphones: inside the cabin and outside. It is very important that the microphone has high sensitivity, as well as the possibility of turning it off if necessary. Another criterion for choosing a DVR is the volume of a memory card on which the video is recorded. The larger it is, the higher the video recording speed and the longer the video can record the camera. The standard SD card size is 32 GB. However, now you can buy a DVR with a large size of memory. Thus, planning to buy a DVR, it is worth determining in advance to its main parameters so that this device fully satisfies the needs of the motorist. https://cryptobrokers.top/in/vietnam
