8Channel UTP RJ45 Passive Video Balun Transceiver For CCTV Camera BNC Male 8CH

UTP Video Balun 8CH

Key Features and Specifications

Connectivity: These baluns typically feature multiple BNC female connectors (one for each channel) on one side to connect to cameras or a DVR, and a single RJ45 jack or screw terminals on the other for the UTP cable.
Video Formats: Most 8-channel baluns are compatible with multiple high-definition analog formats including HD-CVI, HD-TVI, AHD, and traditional analog CVBS (NTSC/PAL/SECAM) signals.
Transmission Method: They convert the 75-ohm coaxial video signal into a balanced 100-ohm signal suitable for transmission over UTP wiring. Each twisted pair within a single Cat5/5e/6 cable can transmit one video signal, allowing one 8-core Cat5 cable to carry four video channels simultaneously.
Passive vs. Active:
- Passive baluns (most common): Do not require external power and can transmit color video signals up to approximately 300-400 meters (around 984-1200 feet).
- Active baluns: Are powered devices (usually AC 85-265V input) that include signal amplification, enabling much longer transmission distances of up to 1800 meters (color) or 2400 meters (black and white) when used with an active transmitter.
Built-in Protection: Many models feature built-in transient suppression, surge protection, and lightning protection to safeguard connected video equipment against voltage spikes and electrical noise.
