Baluns, Extenders, and Video Hubs Series


Active Video Balun Receiver

The EVT-TB1-42TQ and EVT-RB1-4T2Q active video baluns are the quick, low-cost way to connect CCTV cameras to a monitor, multiplexer, or video recorder at up to 1.5 miles (2,400 meters) away for monochrome cameras, or up to 1 mile (1,500 meters) away for color cameras. The baluns allow a CCTV camera's video signal to be transmitted over low-cost Cat 5e unshielded twisted pair (UTP) cable instead of costly coax cable. They are suitable for full-motion color and monochrome cameras.



  • * Active operation -- The transmitter amplifies the video signal for excellent picture quality at long distances.
    * Transmits video signal up to 1.5 miles (2.4km).
    * Uses low-cost CAT5e/6 unshielded twisted pair cable instead of costly coaxial cables.
    * Includes BNC connectors and removable terminal blocks -- No need to waste time crimping RJ-45 connectors.
    * High immunity from interference -- Built-in impedance coupled device and noise filter.
    * Easy installation.
    * Gold-plated BNC connectors.
    * Surge protection. Ground lifting and transient protection.
