4.2 Important Notes on Connection

The camera uses a 2.5mm jack to 4-pin connection. Do not attempt to connect it to a 3.5mm AV-IN video input port.
Ensure your carplay screen supports AHD-1080P-PAL 25hz for optimal performance.

5. Operation

Once installed, the camera will automatically activate when your vehicle is shifted into reverse, displaying the rear view on your compatible carplay screen.

5.1 Adjusting Image Settings (Mirror/Non-Mirror Image)

The camera defaults to a mirror image (rear view). To switch to a non-mirror (front view) image, locate the small green wire loop near the camera connector. Ensure the camera is powered off before making any changes.

Default (Rear View - Mirror Image): The green wire loop is intact.
Front View (Non-Mirror Image): Cut the green wire loop.

Mirror image adjustment by cutting green wire — Figure 6: Instructions for switching between mirror and non-mirror images by cutting the green wire.

5.2 Adjusting Video Resolution (1080P/720P)

The camera defaults to HD 1080P. If your monitor defaults to 720P or displays a black and white screen, you may need to adjust the camera's resolution. Locate the small white wire loop near the camera connector. Ensure the camera is powered off before making any changes.

Default (HD 1080P): The white wire loop is intact.
HD 720P: Cut the white wire loop.
Restore 1080P: Reconnect the white wire loop.

Resolution adjustment by cutting white wire — Figure 7: Instructions for switching between 1080P and 720P resolutions by cutting or reconnecting the white wire.

Important: Always power off the camera and monitor before cutting or reconnecting any wires to prevent damage.

If you are unsure which format your monitor supports, try cutting/connecting the white wire to see if the image appears correctly.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your backup camera.

Cleaning the Lens: Regularly clean the camera lens with a soft, damp cloth to remove dirt, dust, or water spots that may obstruct the view. Avoid abrasive cleaners.
Cable Inspection: Periodically inspect the video cable and power connections for any signs of wear, damage, or loose connections. Secure any loose wiring.
Mounting Security: Ensure the camera's mounting bracket remains secure. Tighten screws if necessary to prevent vibration or displacement.
Waterproof Integrity: While the camera is IP68 waterproof, avoid directing high-pressure water jets directly at the camera during car washes, as this could compromise the seal over time.

If you encounter issues with your Epronic backup camera, refer to the following common problems and solutions.

Problem	Possible Cause	Solution
No image on screen / "No Signal" message	Incorrect connection. Incompatible monitor/signal format. Loose power or video cable. Camera malfunction.

Poor image quality (blurry, dark at night)	Dirty lens. Low light conditions exceeding camera capability. Incorrect resolution setting.	Clean the camera lens. Ensure the camera is set to 1080P if your monitor supports it. Consider additional lighting if operating in extremely dark environments.
