GPS logger - a device that allows you to track the route, location, as well as the speed of movement of the car. The coordinates and speed of the vehicle are displayed on the DVR's display and displayed on the recorded video.

Other useful features of DVRs
The more the angle of view of the DVR, the more details will get into the frame. The optimal viewing angle is 140 degrees or more. It should be noted that if the viewing angle is too large (170 ° and more), then sometimes the effect of the "fish eye" is observed, that is, the video is lapped around the edges.
Internal memory is needed for the DVR to quickly copy important clips from the memory card to the DVR's memory, thereby protecting these videos from overwriting.
DVRs with built-in battery can be used not only as a recorder in a car, but also as a portable camera outside the car.
G-sensor - shock sensor. The principle of its operation is this: in case of sudden braking / accelerating or tilting the car, the video will automatically be saved to a separate folder and will be protected from overwriting.
Parking shooting allows you to shoot at a time when the car is parked. For a parking survey, the registrar needs constant power.
With DVRs they buy
Cigarette Lighter Splitters
Not all cars are equipped with several cigarette lighter sockets, and in the current reality, with many useful devices operating from the cigarette lighter, it is difficult to do just one jack. Using the cigarette lighter socket, you can simultaneously connect several devices to the cigarette lighter, for example, a DVR, a radar detector and a charger for the phone.
Memory cards are a must for the DVR. The larger the volume of the map - the more videos you can record. For faster operation of the DVR, it is recommended to take memory cards no lower than the 10th grade. If the card class is lower - there may be short pauses between the rollers.
