This article will discuss video ground loop problems in CCTV installations. The cause and how it effects picture quality with solutions to eliminate the problem.
The GB-60 UTP Ground-Loop Blocker for Twisted Pair wire is an active device used with any Unshielded Twisted Pair video transmitter or passive "Balun" to eliminate Ground Loop Interference and picture quality problems in new and existing CCTV video installations.
The GB464 Ground-Loop Blocker is an active device used to eliminate Ground Loop Interference and picture quality problems in new and existing CCTV video installations. The unit is installed at the monitor site where the CCTV signals come together, or at any intermediate point where
The GB-1 Ground-Loop Blocker is an active amplifier used to eliminate Ground Loop Interference and picture quality problems in new and existing CCTV video installations. The unit is installed at the monitor site where the CCTV signals come together, or at any intermediate point in
The GB474PTZ Ground-Loop Blocker is an active device used to eliminate Ground Loop Interference and picture quality problems in new and existing CCTV video installations. This product will allow "Up the coax Remote Control Pan, Tilt, and Zoom" operation and will extend the range of
When designing a CCTV system there are four factors that control the maximum image quality that can be obtained. One or more of these factors can degrade the system like a chain with a weak link the weak link in the system limits the quality
It is now possible to transmit clear pictures over new, and existing coaxial cable for up to a mile with no picture detail degradation using the new APR-474 AUTOMATIC PICTURE REJUVENATOR at the receiving end of the coaxial cable. This will open up many picture
All cables introduce some loss of picture brightness and clarity. The longer the cable run the greater the loss. The loss of picture clarity is usually more noticeable than the loss of brightness as the cable length between the camera and the monitor becomes greater.
When pricing out the cable to use to build a Closed Circuit Television System (CCTV) to connect cameras to a central monitor location, many system operators are seduced by the much cheaper price of CATV cable. After all the specs quoted about the transmission at,
Long Coaxial and Unshielded Twisted Pair (UTP) cables are a major cause of picture quality loss on Closed Circuit Television (CCTV) systems. No matter how sharp the picture a Camera can produce, or how clear the Monitor, the cables connecting them can appear to "defocus"
