Configuración e instalación
1. Montaxe da Dash Cam
Ensure the windshield surface where you plan to mount the dash cam is clean and free of dust or grease. The dash cam comes with adhesive pads for secure mounting.
- Attach the front dash cam to the windshield, ideally behind the rearview mirror, to avoid obstructing your view.
- Mount the rear camera on the rear windshield. Route the cable neatly along the vehicle's interior trim.
- Adjust the camera lenses to ensure optimal viewing angles for front, rear, and internal coverage. The side cameras are adjustable up to 180 degrees.

2. Conexión de alimentación
You have two options for powering your dash cam:
- Using the Car Charger (Cigarette Lighter):
Connect the provided car charger to your vehicle's cigarette lighter socket and the dash cam's USB Type-C port. This method is quick and easy for basic recording during driving. Note: Parking monitoring will not function with this method unless the cigarette lighter port is continuously powered when the car is off.
- Using the Hardwire Kit (for 24H Parking Monitoring):
For continuous 24-hour parking monitoring, use the included hardwire kit. Connect the hardwire kit to your car's fuse box (ACC for switched power, BAT+ for constant power, and GND for ground). This ensures the dash cam receives power even when the vehicle is turned off, enabling parking surveillance. Professional installation is recommended for hardwiring if you are unfamiliar with car electrical systems.
