crosstalk between the camera and the monitor are all some of the causes. In these cases it
is best to replace the existing cable with a new one.
Loss of Color and Image Detail
Loss of color or image detail may occur if twisted pair cable length exceeds the distance
specifications. As one approaches the maximum specified distance, the physical
limitations of the cable and baluns will become apparent, mainly due to signal
propagation delay and attenuation. Aside from using an in-line amplifier to restore the
signal, one could improve the image by shortening the length of twisted pair or by
eliminating other contributing signal losses such as splices, cross-connects, low-grade
patch cables, etc. A further solution is to double up the twisted pairs as described later in
this document.
Interference Patterns
If a faint moving interference pattern is present, it may be related to noise injected by the
electrical system or by the presence of a ground loop. Sometimes grounding the audio or
video shield to earth ground, the picture may be cleared up. See the next section for
more information about ground loop.
