      If your Lorex Security Camera shows no picture or signal, there might be several reasons: * Ensure the camera is connected to an MPX Series DVR, as it is not compatible with other DVR models. Check www.lorextechnology. com for compatibility information. * Verify that your TV is on the correct input channel (INPUT, AV CHANNEL, LINE1, LINE2, AUX). * Confirm that your DVR is properly connected to your TV or monitor. * Make sure you have the correct camera for your system. 1080p cameras are compatible with 1080p HD DVR recorders; 720p cameras are compatible with 720p & 1080p HD DVR recorders. * Ensure all connections are properly connected. * Check that the camera power supply is plugged in.

      If the picture from your Lorex Security Camera appears too bright, it could be due to the camera pointing directly at a light source. Make sure your camera isn’t pointed directly at a source of light, such as the sun or a spotlight. If that doesn't help, try moving your camera to a different location.
