Self-contained 4, 8, 16 and 32 channel Video Balun Transmitter and Receiver Hubs. These Nitek Video Balun Hubs are designed for use over point-to-point unshielded twisted pair wiring. Active Video Balun Receivers come equipped with DIP switches providing easy set-up and adjustment which allows the installer to “fine-tune” each channel to the exact cable length. Nitek’s unique method of setting video gain and equalization eliminates service calls and speeds up installation, especially over longer distance cable.
