5. Operation

5.1 Basic Recording

Once powered on, the dash camera will automatically start continuous loop recording. Video segments are saved to the MicroSD card. When the card is full, the oldest unlocked videos will be overwritten.

5.2 G-Sensor (Emergency Lock)

The built-in G-sensor detects sudden movements or collisions. When triggered, it automatically locks the current video segment to prevent it from being overwritten by loop recording.

5.3 24-Hour Parking Mode

In parking mode, the dash camera detects vehicle vibrations and automatically records a 1-minute video. This feature requires a continuous power supply (hardwire kit, sold separately, may be needed for continuous power when the vehicle is off).

This image demonstrates the 24-hour parking monitor, which utilizes time-lapse recording at 1 frame per second to continuously monitor your car without consuming excessive storage capacity.

5.4 Wi-Fi Connectivity and App Control

The built-in Wi-Fi allows you to connect your smartphone to the dash camera via a dedicated app. Through the app, you can:

• View live footage.
• Change camera settings.
• Download recorded videos to your phone.

5.5 GPS Functionality

The integrated GPS module records your driving route, location, and speed, providing valuable data that can be viewed alongside your video footage.

5.6 Smart Voice Control

The dash camera supports 11 voice commands, allowing hands-free operation for functions such as turning on Wi-Fi, locking videos, turning on the screen, and taking photos.

This image highlights the smart voice control feature, listing examples of commands like "Turn on Wi-Fi," "Lock the video," "Turn on screen," and "Take photo," enabling hands-free operation while driving.

5.7 Backup Rear Camera Function

The rear camera supports reversing assistance. When the reversing light is activated (and the red wire is correctly connected), the recorder automatically switches to a full-screen image of the rear camera to aid in parking maneuvers.
