Balun stands for Balanced – Unbalanced. Physically, it is a small transformer used to convert video signals from balanced to unbalanced, and vice versa. Its practical use is in creating required impedance adjustments for signal transmission between differing wiring systems (like UTP to coaxial cable). Specifically used to be able to transmit the video signal in a CCTV Security Camera System on Unshielded Twisted Pair (UTP), such as Cat5, instead of using RG59U coax cable. Typically standard distance that the signal can be transmitted is about 1200 feet. The distance can be significantly increased with what is called active instead of the more commonly used passive type.Get Free Video Surveillance Systems Quotes!
