Operating Instructions
Basic Recording
The dash cam will automatically power on and start recording when your vehicle's ignition is turned on. It will automatically power off when the ignition is turned off.
Loop Recording
The device supports seamless loop recording. When the memory card is full, the oldest unlocked video files will be automatically overwritten to make space for new recordings. This ensures continuous recording without manual intervention.

G-Sensor (Gravity Sensor)
The built-in 3-axis G-sensor automatically detects sudden impacts or collisions. When a significant shock is detected, the current video footage will be locked and saved to a separate folder, preventing it from being overwritten by loop recording. This ensures critical event footage is protected.
24-Hour Parking Monitor
With a properly installed hardwire kit, the dash cam can monitor your vehicle 24/7. If an impact or collision is detected while parked, the dash cam will automatically record the event. This feature often utilizes time-lapse recording to conserve storage space.

Reversing Camera Function
When you engage reverse gear, the dash cam display will automatically switch to the rear camera view, often showing parking guidelines to assist with accurate and safe reversing. This helps reduce blind spots and prevent accidents.

Night Vision and Exposure Compensation (WDR)
The dash cam is equipped with IR night vision for clear interior recordings in low light. The Wide Dynamic Range (WDR) feature automatically adjusts exposure to balance bright and dark areas, ensuring clear video quality even in challenging lighting conditions, such as driving at night or exiting tunnels.
