Operating the Dash Cam

1. Recording Modes

  • Loop Recording: The dash cam continuously records video in short segments (e.g., 1, 2, or 3 minutes). When the memory card is full, the oldest unlocked files are automatically overwritten by new recordings. This ensures continuous operation without manual intervention.
  • G-Sensor (Emergency Lock): The built-in G-sensor automatically detects sudden impacts or collisions. When an event is detected, the current video segment is locked and saved to a protected folder, preventing it from being overwritten by loop recording. This footage serves as crucial evidence in case of an accident.

2. Parking Monitoring

The dash cam offers 24-hour parking monitoring to protect your vehicle when it's parked. This feature requires a hardwire kit (not included) for continuous power supply.

  • Time Lapse Mode: Records continuously at a low frame rate, minimizing power consumption and storage space while providing comprehensive coverage.
  • Collision Detection Mode: If the G-sensor detects an impact while parked, the dash cam will automatically wake up and record a short video segment.

Note: For 24-hour parking monitoring, a hardwire kit is required and sold separately.

3. Video Quality Features

  • 4K Ultra HD Front Camera: Records at 3840x2160P, capturing clear details like license plates and road signs.
  • 1080P Rear Camera: Records at 1920x1080P, providing a clear view of the rear. The rear camera is 360° rotatable for flexible positioning.
  • Super Night Vision: Equipped with a large F/1.8 aperture 6-layer optical lens and WDR (Wide Dynamic Range) technology, the camera enhances exposure in dark situations, ensuring clear images in low-light environments.
  • CPL Filter: The magnetic Circular Polarizer (CPL) filter reduces glare and reflections from the windshield, especially in bright sunlight or from headlights at night, improving video clarity and contrast.
