What to do if I have no picture or signal on my Defender Security System?

If you are experiencing no picture or signal on your Defender Security System, ensure all connections are secure and properly connected. Verify that your receiver is plugged into a power source using the 9VDC input on the back. Make sure there are no obstructions blocking the camera's view. If problems persist, try re-pairing the camera and receiver.
