distance from the front vehicle and warns the driver when
approaching too close.
4. Collision warning
The GDR 190 has a built-in G-sensor that detects
collision accidents and triggers recording. Record-
ed video files are stored in a protected state. This
function is turned on by default. When the colli-
sion sensor is on (i.e. when set at High, Normal, or
Low sensitivity), the unit will sound three "beeps"
whenever a collision is detected.
After the sensor detects a collision, the system
will automatically lock down the current file being
recorded, as well as the previous file and the file
after the collision, therefore ensuring continuity of
the accident.
