Built-in GPS Functionality
The integrated GPS module records your exact driving route, location, and speed directly onto the video footage. This data can be viewed on your phone via the RoadRec app or on a PC/Mac using Sarmert's free GPS Player, providing crucial evidence in case of an incident.
HDR Night Vision with Sony STARVIS Sensor
Equipped with a Sony STARVIS Image Sensor, a six-glass lens array, f/1.8 aperture, and WDR (Wide Dynamic Range) technology, the C1 captures vivid and detailed footage even in low-light conditions. The 150° ultra-wide angle minimizes blind spots, and adjustable EV exposure allows for optimal clarity.

G-Sensor and Emergency Video Lock
The built-in G-Sensor automatically detects sudden shakes or collisions. When triggered, it locks the current video segment, preventing it from being overwritten by loop recording. This ensures critical footage is secured as evidence.
24-Hour Parking Monitor
For continuous surveillance when parked, the 24-hour parking monitor activates upon collision or motion detection. It also supports time-lapse recording for extended coverage. Note: This feature requires the purchase and installation of an additional hardwire kit (not included).
