Video balun
| CCTV glossary (глоссарий терминов по видеонаблюдению) |
A video balun (sometimes referred to as a utp balun), enables an installer to replace traditional coaxial cable with cat5 and other forms of twisted pair cabling, to wire security cameras in analog cctv installation applications. video baluns enable cat5 cabling to be run over longer distances for less money than coaxial cable.

Balun, английский
- Balanced/unbalanced
- Устройство для соединения симметричного кабеля (например, utp) с несимметричным кабелем (например, коаксиальным) с согласованием импеданса
- A video balun enables the transmission of video using unshielded twisted pair wire instead of coaxial cable. the word "balun" comes from combining the terms balanced and unbalanced. the function of a balun is to transform an unbalanced signal into a balanced signal. when video signal is transmitted through coaxial cable, the distance traveled by the signal is limited because the signal is in the form of an unbalanced signal that is susceptible to radio frequency interference or noise. coax cable incorporates special shielding to minimize noise. video baluns transform the video signal into a balanced form in which each wire in the twisted pair transmits an identical signal with opposite polarized magnetic fields. noise affects each signal equally. when the signals are combined, the noise is cancelled out. by using a designed balun, an unshielded twisted pair wire can transmit video for much longer distances than coax cable and with a lower cable cost.
- A transformer that levels out impedance differences, so that a signal generated on to a coaxial cable can be transferred on to a twisted pair cable.
- This is a device used to match or transform an unbalanced coaxial cable to a balanced
- Balanced-to-unbalanced (converter)
- This is a device used to match or transform an unbalanced coaxial cable to a balanced twisted pair system.
