Commercial Camera extensions should not exceed 100 feet. If experiencing signal loss with a standard definition cable (TE-CEX), upgrade to a high definition cable (TE-HEX). The TE-HEX cables have a thicker copper cabling that helps with the signal loss and allows for the distribution of high definition signal.

If after a camera is installed you experience a “rolling line”, check your ground. The most common cause of this would be the grounding of the camera itself. The second cause would be a loose or broken ground in the RCA itself; this would require a replacement of the camera.

If after a camera is installed you experience a black and white image, check your ground. Check the ground on the monitor and the camera. A bad ground will not allow the processor to turn on fully, which results in a black and white image.

If you are not getting an image after the install of a TE-HPC commercial camera, check and make sure the extension being used is a TE-HEX cable. The TE-HPC cameras are high definition and are required to be used with the high-definition cable. The same would apply for the monitor as well. The TE-HPC cameras MUST be used with the TE-4HCM-S monitor.
