4. Operating Instructions

4.1 Driving Recording

The dash cam automatically begins recording when your vehicle starts. It records simultaneously from the front 4K camera and the rear 1080P camera.

  • 4K Front & 1080P Rear: Captures high-resolution video from both directions, ensuring comprehensive coverage.
  • HDR (High Dynamic Range): Balances light and shadow, reducing glare and overexposure for clear details in challenging lighting conditions.
  • Enhanced Night Vision: With an F1.55 aperture and advanced technology, the dash cam records clear and balanced videos in low-light conditions, tunnels, and rain.
  • Loop Recording: Continuously records, overwriting the oldest files when the SD card is full, ensuring uninterrupted recording. Emergency recordings are protected from being overwritten.

5. Maintenance
