4Channel Video Quad Image Multiplexer Processor for CCTV Surveillance Cameras A compact, easytoinstall multiplexer that combines four video inputs into a quad display and a single output for monitoring and recording. Designed for CCTV surveillance environments, this processor adds practical control features to help operators focus on important events and reduce missed incidents. Key benefits Centralized monitoring: View four camera feeds simultaneously on one monitor to simplify surveillance and reduce the need for multiple displays. Faster incident assessment: Digital zoom and video freeze allow operators to inspect details and hold critical frames for closer review without interrupting ongoing monitoring. Improved event detection: Motion detection and video loss alarm alert operators to potential problems so they can respond quickly and reduce blind spots. Audio support for context: Builtin audio in and out support lets you capture ambient sound alongside video, improving evidence value and situational awareness. Reliable integration: Works with standard CCTV camera setups to consolidate video feeds and feed recorders or monitors. Core functions and features 4channel input with quad output display for simultaneous monitoring of four cameras. Digital zoom to magnify areas of interest within each channel without changing camera settings. Video freeze to hold a frame for detailed inspection or review. Video loss alarm to notify operators when a camera feed is interrupted or disconnected. Motion detection to trigger alerts or recording on activity in selected areas. Support for audio in and audio out to add or route sound alongside video. Simple controls for switching display modes and accessing processor functions. Compatibility, size, and build Designed for use with conventional CCTV surveillance cameras and monitoring systems. Compact form factor suitable for desktop or small equipment rack placement. Durable housing suitable for typical security equipment environments. Lowlatency processing for realtime monitoring and responsive controls. Performance and reliability Stable multiplexing of four video channels with consistent output to a single monitor or recorder.
