2. Power On and Test: Before permanent installation, connect the dash cam to power using the provided car charger and test all functions to ensure proper operation.

3.2 Mounting the Dash Cam

1. Clean Windshield: Choose a suitable location on your front windshield, ideally behind the rearview mirror, to minimize obstruction of your driving view. Clean the area thoroughly.
2. Attach Suction Mount: Secure the suction mount to the cleaned area on the windshield. Ensure it is firmly attached.
3. Attach Dash Cam: Slide the main dash cam unit onto the suction mount until it clicks into place. Adjust the angle of the dash cam to capture the desired view of the road ahead.

3.3 Rear Camera Installation

2. Route Cable: Carefully route the rear camera cable from the rear windshield to the front dash cam. Use the provided cable clips and a crowbar tool (if included) to tuck the cable neatly along the headliner, A-pillar, and under the footpad to conceal it.
3. Connect Rear Camera: Plug the rear camera cable into the designated port on the main dash cam unit.

3.4 Power Connection

1. Connect Power Cable: Insert the Type-C head of the power cable into the dash cam.
2. Route Power Cable: Route the power cable along the front windshield gap, down the A-pillar, and hide it under the passenger seat footpad, similar to the rear camera cable.
3. Plug into Cigarette Lighter: Plug the car charger end of the power cable into your vehicle's cigarette lighter (12V power outlet).

3.5 General Installation Guidance Videos

The following videos provide general guidance on dash cam installation and cable management. While they may feature different dash cam models, the principles of installation are broadly applicable.

4. Operating Instructions

4.1 Automatic Operation

The dash cam is designed for automatic operation. It will automatically turn on and begin recording when your car engine starts, and turn off when the engine is switched off. This ensures that every moment of your drive is captured without manual intervention.

4.2 Loop Recording

The dash cam utilizes loop recording, which continuously records video in segments. When the memory card is full, the oldest unlocked footage will be overwritten by new recordings. This ensures uninterrupted recording without the need for manual memory management.

4.3 Emergency Accident Lock (G-Sensor)

The built-in G-sensor detects sudden impacts, collisions, or emergency braking. When triggered, it automatically locks the current video file, preventing it from being overwritten by loop recording. This preserves critical evidence of incidents.

4.4 Motion Detection

When enabled, the motion detection feature allows the dash cam to start recording automatically if it detects movement in front of the vehicle while parked. This provides surveillance and helps capture incidents like hit-and-runs.

4.5 Parking Monitor

With continuous power supply, the parking monitor function allows the dash cam to monitor your car's condition 24 hours a day. It can record events even when the vehicle is parked, offering protection against vandalism or theft.

4.6 Reviewing Footage

Footage can be reviewed directly on the dash cam's 4.0-inch screen or by transferring the Micro SD card to a computer using the provided USB transfer cable. This allows for easy access and playback of recorded videos.

6. Maintenance

• SD Card Formatting: Regularly format the Micro SD card to ensure optimal performance and prevent data corruption. This can typically be done through the dash cam's settings menu.
• Lens Cleaning: Keep the camera lenses clean and free from dust or smudges to ensure clear video quality. Use a soft, lint-free cloth.
• Firmware Updates: Check the manufacturer's website periodically for any available firmware updates to improve performance or add new features.

7. Troubleshooting

• Camera Not Turning On: Ensure the power cable is securely connected to both the dash cam and the car's cigarette lighter. Check if the car's 12V outlet is functioning.
• Recording Issues: If the camera is not recording, check if the Micro SD card is inserted correctly and has sufficient free space. Format the SD card if necessary.
• Poor Video Quality: Ensure the lenses are clean. Check the video resolution settings and adjust if needed. Poor lighting conditions, especially for the rear camera, can affect quality.
• G-Sensor Too Sensitive/Not Sensitive Enough: Adjust the G-sensor sensitivity setting in the dash cam's menu.
