This can provide for most of the outside of the traditional voice and data. The benefits of a 4th generation video solution to Closed Circuit Television (CCTV) and security legacy camera systems. market, previously dominated through the use of coaxial cabling solutions, can now be provided for As an alternative to IP camera based systems, for by using far more cost effective structured cabling legacy, non-IP CCTV systems or those requiring high solutions. resolution/high frame rate monitoring systems for highly secure, real-time environments like banks, Post 9/11 there has been a dramatic increase in casinos, etc has been the development of “CCTP” the requirement for cost effective video surveillance or CCTV over twisted pair. CCTV, up until now, was and security monitoring. Fuelled by this demand reticulated through 75 ohm coaxial cabling has been the development of a number of (typically RG-6). Through development in balun technologies to reduce the cost of implementing technologies, it is possible to incorporate CCTV what was previously projects requiring large signals into structured cabling systems. To apply investments in both the active devices involved and structured cabling connectivity to CCTV, a reliable the passive infrastructure supporting them. way is needed to adapt the video signal to the twisted-pair cable. The CCTV balun is key to this As a result of this requirement and other conversion. The CCTV balun is a passive element circumstances, coupled with the ongoing march of that converts the unbalanced signal of the coaxial IP convergence, the result has been the cable to the balanced signal of the twisted-pair. The development of the so called 4th generation video
