Setup & Installation
Follow these steps for proper installation of your dash cam system:
- Prepare the Windshield: Clean the area on your front windshield where the dash cam will be mounted. Ensure it is free of dust and grease.
- Apply Electrostatic Film: Paste the electrostatic film near the top of the front windshield, ensuring it does not obstruct your view. This film allows for easy removal of the dash cam mount without leaving residue.
- Mount the Front Camera: Attach the adhesive mount to the electrostatic film. Slide the main dash cam unit onto the mount until it clicks securely into place.
- Insert Memory Card: Insert the provided 32GB memory card into the designated slot on the dash cam.
- Connect Power: Connect the USB power cable to the dash cam and route it along the edge of the windshield and dashboard using the provided cable management tool. Plug the car charger into your vehicle's cigarette lighter socket.
- Install Rear Camera: Mount the rear camera on your rear windshield using its adhesive mount. Connect the rear camera to the main dash cam unit using the long connection cable, routing the cable discreetly along the vehicle's interior trim.
- Adjust Camera Angle: Power on the dash cam and adjust the lens angle of both front and rear cameras to ensure optimal recording coverage.

Parking Mode
The 24-hour parking mode provides continuous surveillance for your vehicle even when it's parked and the engine is off. This feature helps protect your car from incidents like hit-and-runs or vandalism.
- Activation: Parking mode requires the separate purchase and installation of a hardwire kit (Model: B0FLPT6F86). This kit ensures continuous power supply to the dash cam from your car's battery without draining it.
- Functionality: Once the hardwire kit is installed and parking mode is enabled in the settings, the dash cam will automatically switch to parking surveillance when your vehicle is turned off. It can perform time-lapse recording or event-triggered recording (e.g., G-sensor detection of impact).
