Operating Instructions
Basic Operation
- Power On/Off: The camera powers on automatically with vehicle ignition and powers off when the ignition is turned off. You can also manually power it on/off using the power button.
- Recording: Once powered on, the camera begins recording automatically. The 3-inch LCD display shows the live view from the front and rear cameras.
- Loop Recording: The camera records video in continuous loops. When the memory card is full, the oldest unlocked files are overwritten by new recordings.
Key Features
- Ultra HD Dual Channel Recording: Records front footage in 4K (5MP) and rear footage in 2.5K QHD, providing detailed video evidence.
- 170° Wide Angle Lens: Captures a broad view of the road, minimizing blind spots.
