4 Channel Video Multiplexer and Transmitter/Receiver Set Key benefits Reliable interference resistance: Modular design minimizes signal interference for stable, clear video transmission. Iron shell construction adds physical durability for demanding installations. Plug and play setup: No debugging or terminal adjustments required. Connect the units and they are ready to operate, with hot swap support for service or expansions without system downtime. Long distance performance: Supports stable video transmission up to 400 meters between transmitter and receiver, suitable for large properties and extended surveillance networks. Flexible signal handling: Transmit one channel as a direct pass through while superimposing three channels, enabling adaptable monitoring and recording configurations. Features and performance 4 channel video multiplexer that combines one pass through channel with three superimposed channels for flexible surveillance layouts. Robust modular construction for improved resistance to electromagnetic interference and easier maintenance or replacement of components. Durable iron shell housing for enhanced protection in continuous operation and challenging environments. Hot swap capability to allow fast camera or module replacement without interrupting the overall system. Designed for straightforward installation and reliable long distance transmission when used as a matched transmitter and receiver set. Compatibility and use Works with standard analog video surveillance cameras and receiver equipment requiring multiplexed or combined video feeds. Compact modular format fits into rack or enclosure installations where space and protection are considerations. Typical applications Multicamera surveillance across a large estate, campus, or industrial site where runs up to 400 meters are required. Security system expansion or temporary deployments that require quick, tool installation and hot swap access. Central monitoring rooms that need one direct channel for live viewing plus three superimposed channels for recording or analysis. This device delivers interferenceresistant, long range video transmission with easy installation and flexible signal options to support reliable surveillance deployments.
