What is the registrar almost everyone knows. This is a very useful thing that can serve the right service.
But how to choose the right device? What moments should be paid close attention to? What characteristics are important?
Before buying a device, you need to understand that for a good DVR, the price will be rather big.
Pay attention to the following parameters.
Record and its quality. The quality of the recording directly depends on speed and resolution.
Permission. The clarity of the picture will depend on the resolution. Standard is considered an image of 640 by 480. However, such permission cannot be called high -quality, since it is almost impossible to see the numbers of nearby cars on video recordings with such resolution. Better quality, a record made using devices having a resolution of HD (1280 by 720 and 1920 by 1080). It is probably clear that the more resolution will be, the picture will be more clear. So, the video can be seen all the details.
The speed with which the recording is made. The larger the speed with which the device records the video, the better it will be viewed on the video movement. In addition, the video can be watched in a slow view mode or each frame separately. This is very convenient in cases where there is a need to clearly see all the details. In order to get a high -quality image, the device must record a video at a speed of at least 50 frames in a second.
Preservation of the video. Pay attention to the moment that the memory card accepts the DVR you like.
Fastening. The rule that should be in the first place is that the DVR should not close the review. There are DVRs that are attached to glass, devices built in the mirror and devices, the cameras of which are connected separately.
