Mount the camera, which is integrated into a license plate frame, onto your vehicle's rear license plate. Ensure the camera lens is unobstructed and positioned for optimal viewing. The camera is designed to fit US standard license plates.


5.2 Step 2: Power Connection
Connect the power wire of the backup camera to a 12-36V DC power source. This can typically be done by connecting to your vehicle's running lights, reversing lights, or an auxiliary charging circuit. When the connected light/power source is active, the camera will power on.

Once the camera is powered on, it will create its own WiFi signal (e.g., "SONIX_XXXXXX"). Go to your mobile device's WiFi settings and connect to this network. Note: This WiFi network does not provide internet access.

Launch the "MH Cam" application on your mobile device. The app will automatically connect to the camera's WiFi signal and display the live video feed.
