Overview
The Quad Video Balun allows up to four composite
video signals to be transmitted via unshielded twisted
pair (UTP) cable in a point-to-point connection.
Used in pairs, the Quad Video Balun allowing video
equipment to be connected via space-efficient and
cost-effective Category 5/6 twisted pair cable.
The Quad Video Balun supports NTSC, PAL,
SECAM video formats for classroom video,
commercial and Home video systems, hospital video
training,video conferencing, podium presentation
Systems and video kiosks applications and so on.
Applications
Security video, classroom video, commercial and
home audio/video systems, hospital video training,
video conferencing, podium presentation systems
and video kiosks.

Quick Setup Guide:
Plug the RCA connectors of the transmit Balun into the
Video outputs of the source component you wish to
transmit. Plug the Video connectors from the receive
Balun into your desired input component. Insert the CAT5
cable into both ends of the Baluns. You may use standard
EIA 568A/B termination.
