Product overview This 2 channel coaxial video signal multiplexer and adder functions as a video converter for CCTV systems, allowing two analog camera signals to share a single coaxial run for transmission and later recovery. It is designed to simplify cabling, reduce installation complexity, and improve resistance to typical coaxial line interference. Key benefits Simplifies cabling and installation by combining two camera feeds onto one coaxial cable and separating them at the receiving end. Ideal where pulling additional cable is difficult or costly. Improves signal stability during transmission through design features that reduce common coaxial noise and crosstalk. Plug and play operation requires no software or complex configuration, making it suitable for quick field deployment by installers and technicians. Compact and lightweight for easy mounting inside cabinets, racks, or tight enclosures. Main functions and features 2 channel multiplexing and conversion: merges two analog video channels into a single coaxial transmission path, and recovers them at the corresponding receiver. Compatibility: built for analog CCTV camera systems that use coaxial cabling and standard video inputs at the control or recording equipment. Works with common DVR and monitoring setups that accept coax input. Standard coaxial connectors for easy integration with existing cabling and connectors. Designed for reliable signal transmission over typical coaxial distances used in surveillance installations. Durable enclosure and straightforward cabling keep installation tidy and maintenance simple. Practical attributes Function: video adder and converter for twochannel coaxial transmission. Compatibility: analog CCTV cameras and DVRs that accept coaxial video signals and standard coaxial connectors. Size and installation: compact form factor suitable for confined spaces and equipment racks; installs quickly using basic tools. Materials and build: robust housing to protect the electronics during normal installation and operation. Performance: maintains clear video paths for two channels while minimizing signal degradation caused by interference on coaxial runs. Use scenarios Retail store retrofit: combine two existing camera feeds into one coaxial line to reach a remote DVR without running additional cable through the ceiling void. Residential property with limited conduits: transmit two exterior cameras down a single coax route to the interior recorder, reducing drilling and conduit work. Small industrial or warehouse site: extend monitoring coverage by transporting paired camera signals over long existing coax lines and recovering them at the central control room. Installation notes The solution requires a transmitting unit at the camera end and a matching receiver unit at the monitoring or recording end to recover the two channels. Use quality coaxial cable and connectors to preserve signal quality. Verify compatibility with your recording hardware before installation. This product is a practical tool for installers and system integrators needing to reduce cabling complexity while preserving reliable analog video transmission.
