[4 Channel Front and Rear and Inside Dash Cam] The quad FHD 1920*1080P dash cam's 150-degree super wide-angle lens and 3 inches huge LCD screen give sharper movies and images even when traveling at high speeds, and allow you to re-watch important moments. The first dash cam can simultaneously record the front and sides of the vehicle and the two cabin cameras can freely change the recording angles and rotate left and right allowing you to record in opposite directions as well. [Built-in GPS and Tracking Speed] The new D90-4CH dash camera's integrated GPS allows it to precisely pinpoint the vehicle's location, speed (KMH/MPH), time, and routes on a map in real time. Install and use the GPS player. The right side of the GPS player displays the path trajectory that has been taken and coordinates help track the precise positions of an accident, which is important for roadside help and insurance claims.
