The FS-4504SR-II video balun hub is a passive (non-amplified) device that allows the transmission of real-time CCTV video signal via cost-effectiveUnshielded Twisted Paired(UTP) cable. Baseband (composite) signals of any type are supported.

The construction of FS-4504SR-II is much smaller and compact compared with FS-4504SR. FS-4504SR-II supports pluggable screw terminal or RJ45 connections. Used in pairs, it is capable to transmit 4 channel live CCTV color video signal from camera end and receive 4 channel video signal at DVR end via one UTP cable at distance up to 1312ft(400m). FS-4504SR-II is compatible with all the other FOLKSAFE passive transceiver for application at distance up to 1312ft(400m) and active receiver up to 2296ft(700m).

The superior interference rejection and low emissions of the FS-4504SR-II allow video signals to coexist in the same wire bundle as telephone, datacom,

or low-voltage power circuits. This allows the use of a shared or existing cable plant. It has built-in surge suppressor to protect video equipment against

damaging voltage spikes and provide noise immunity to ensure quality signals without disturbing "hum-bars".

Wire and Cable Recommendations

FS-4504SR-II is recommended to use with Unshielded Twisted Paired (UTP) wiring from 24AWG through 22AWG.Individually shielded pairs should be avoided, as they reduce the operating range of the systems drastically. Multi-pair cable (25-pair or more) with an overall shield are acceptable. Video signals can coexist in the same wire bundle as telephone, datacom, or low-voltages power circuits. While video may be routed through telephone punch-down block terminals, any bridge-taps, also called T-taps and any resistive, capacitive or inductive devices MUST BE removed from the pair.
