D20 QHD 2CH cameras capture every moment on the road in perfect clarity. When the built-in G-sensor detects a sudden shock or collision, the camera will automatically loop-record driving incidents. Also, a full-featured smartphone app supports live streaming, instant download, GPS tracking and SNS sharing. Lastly, it gives the user ADAS (Advanced Driver Assist System) functions (LDWS, FVSA). When the device detects the vehicle in front too close the alarm is automatically triggered.
