4. Betjening
4.1 Tænd/sluk
The dash cam will automatically power on and begin recording when your vehicle's ignition is turned on (if connected via the standard power cable or ACC wire of the hardwire kit). It will power off automatically when the ignition is turned off.
4.2 Optagelsestilstande
- Loop-optagelse: The dash cam continuously records in short segments (e.g., 1, 3, or 5 minutes). When the memory card is full, the oldest unlocked footage is overwritten.
- G-sensor (nødoptagelse): I tilfælde af et pludseligt sammenstød eller en kollision registrerer den indbyggede G-sensor automatisk hændelsen og låser det aktuelle videosegment, hvilket forhindrer, at det overskrives af loop-optagelsen.
- Parking Surveillance (Requires Hardwire Kit UP03): When the vehicle is parked and the ignition is off, the dash cam enters parking mode. It can detect collisions and suspicious activity (AI Motion Detection) and record time-lapse videos to conserve storage.
