- What's Included
Many new homes and office buildings already contain structured cabling systems of not only electrical and phone wiring, but also an inexpensive Cat. 5 twisted pair cable, which is commonly used as a data line. Take maximum advantage of this existing wiring by adding baluns to each end for a fast, easy, and low-cost way to connect a CCTV camera to a monitor, multiplexer or video recorder. The EVT-PB1-V1TSQ Gold-Plated BNC Passive Balun with Surge includes a built-in surge protection circuit to help protect sensitive video security equipment from power spikes. These baluns are designed to work in pairs, but each is sold separately.
How Baluns Work
The Gold-Plated BNC Passive Video Balun converts BNC video signals from unbalanced to balanced and vice versa, making the necessary impedance adjustments for A/V signal transmission between different wiring systems. This means that you can run your surveillance signal up to 2000 feet over inexpensive cat. 5 wiring, rather than rewiring your home in order to send these signals from room to room using expensive coaxial cable.
Passive Balun Requires No Power Supply
No external power supply is required to send surveillance video over cat. 5 cable. Just connect your surveillance camera to the balun to transmit a black & white video signal up to 2000 feet or a color video signal up to 1300 feet. The Gold-Plated BNC Passive Balun has built-in transient protection and high immunity to interference, so your signal will reach its destination as cleanly as possible, without exposing your expensive components to dangerous power surges.
The Gold-Plated BNC Passive Video Balun includes a BNC connector and a screwless terminal block; there's no need to waste time crimping RJ-45 connectors. BNC baluns are also available with male or female snap-in connections.
