The FS-HDP4100C video balun is a passive (non-amplified) device that allows the transmission of real-time CCTV HD video  signal via cost-effective Unshielded Twisted Paired (UTP) cable. The FS-HDP4100C is compatible with all HD-TVI, HD-CVI, AHD and CVBS analog cameras.

The FS-HDP4100C has a mini-coax pigtail lead which allows quick mounting onto fixed cameras, allows in-camera mounting in most dome cameras and allows flexible connection with DVR. Push-pin terminal block allows tool-less connection of UTP cable output.Used in pairs, the FS-HDP4100C eliminates costly and bulky coaxial cable..

The superior interference rejection and low emissions of the FS-HDP4100 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. The FS-HDP4100C is built-in surge suppressor to protect video equipment against damaging voltage spikes. Its crosstalk and noise immunity ensure quality video signals.


1. The actual transmission distance will vary according to the quality of the cable, specific camera, and on-site environment.

2. Please make sure to install transmitter at camera side and receiver at DVR side to achieve best video quality.

3. If you adjust saturation of DVR, video transmission distance could be farther. HD-CVI 720P: max up to 470m (1541ft).

4. If chromatic aberration occurs, please also adjust saturation, the picture will recover perfectly automatically.

5. The device is not waterproof and not to be used at outdoors.

Wire and Cable Recommendations

The FS-HDP4100C 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 is acceptable. Video signals can coexist in the same wire bundle as telephone, data-com, 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, capacity or inductive devices MUST BE removed from the pair.
