5.4 Night Vision with STARVIS 2
The JOMISE A80 Pro utilizes STARVIS 2 technology for both front and rear cameras, providing superior low-light performance. This ensures clear and detailed video capture in challenging lighting conditions such as dark roads, tunnels, and nighttime driving, with reduced noise and improved exposure.

5.5 Ethernet Rear Camera Processing
Unlike traditional AHD systems, the A80 Pro uses an Ethernet-based system for the rear camera. This allows a dedicated processor in the rear camera to handle its footage independently, freeing up the main processor for the front camera. This design improves overall 4K image performance and stability for both front and rear recordings.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the camera lenses and the display screen. Avoid abrasive cleaners or solvents.
- Memory Card: Regularly format the micro memory card (at least once a month) within the dash cam's settings to ensure optimal performance and prevent data corruption. Back up important footage before formatting.
- Firmware Updates: Check the official JOMISE website periodically for firmware updates. Keeping your dash cam's firmware up-to-date can improve performance and add new features.
