5. Operating Instructions
Once installed, the hardwire kit operates automatically:
- Automatic Parking Mode: When your vehicle's ignition is turned off, the hardwire kit will signal your connected dash cam to enter its parking monitoring mode (if supported by the dash cam). This allows for continuous surveillance even when the car is parked.
- Low Voltage Protection: The kit continuously monitors your vehicle's battery voltage. If the voltage drops below 11.8V ± 0.2V, the kit will automatically cease drawing power to prevent excessive discharge of your car battery, ensuring your vehicle can start.

7. Troubleshooting
If you encounter issues, consider the following:
- No Power to Dash Cam:
- Verify the OBD connector is fully seated in the vehicle's OBD-II port.
- Ensure the Micro USB connector is securely plugged into the dash cam.
- Check your vehicle's fuse box for any blown fuses related to the OBD port (consult your vehicle's manual).
- Confirm your dash cam is compatible with a 5V/2.5A Micro USB power input.
- Dash Cam Disconnecting/Restarting:
- This could indicate an unstable power connection. Re-check all connections.
- Ensure the cable is not damaged.
- If the vehicle battery voltage is consistently low, the low voltage protection feature may be activating. Consider checking your vehicle's battery health.
- Parking Mode Not Activating:
- Confirm your dash cam supports parking mode and that it is enabled in the dash cam's settings.
- Ensure the hardwire kit is correctly installed and receiving power.
