FS-4000SR is a single channel passive video transceiver built-in ground loop isolator that mainly uses for solving the signal interference problem caused by potential source of interference. This device features super lightning protection and can be used for security monitoring system.

FS-4000SR is both a transmitter and receiver featuring long transmission distance, good transmission effect and super interference rejection. It is widely used in various complex environment to prevent from interference.

Video signals can coexist in the same wire bundle as telephone, datacom, or low-voltages power circuits. It is very economical and convenient to environment.Compared with traditional audio and video transmission products, FS-4000SR greatly reduce the cost and improve the performance. Compared with other similar products, FOLKSAFE FS-4000SR has higher performance, better stability, and better price advantage.

Wire and Cable Recommendations

FS-4000SR 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.
