Product overview A 4channel AHD and CVBS video multiplexer that lets you combine and manage multiple analog and AHD camera signals for monitoring and recording. Supports 1080P video, longdistance coax runs up to 400M, and operates from a 12V 1A power supply. Hot swappable channels allow camera replacement or service without powering down the system. Key benefits Minimize downtime: Hot swappable channels let you add or cameras without interrupting the rest of the system. Support mixed camera systems: Accepts both AHD and CVBS camera signals so you can integrate older analog cameras with AHD upgrades. Longdistance transmission: 400M coax range helps preserve image quality over extended cable runs common in large properties. Simple power requirement: Uses a standard 12V 1A supply for predictable installation and compatibility with common CCTV power sources. Compact multichannel solution: Fourchannel configuration provides consolidated signal management for small to medium installations. Main features and specifications Channel count: 4 channels, quad multiplexer configuration for multiple camera inputs Video formats: AHD and CVBS compatible for both definition analog and standard composite signals Resolution support: 1080P capability for definition AHD cameras Transmission range: Up to 400M over coaxial cable under typical installation conditions Power: 12V 1A input Hot swap: Individual channel hot swap support for live maintenance and camera changes Function: Multiplexes multiple camera feeds for monitoring, recording, or feed switching without losing signal integrity Compatibility and installation notes Compatible with AHD and CVBS analog cameras and with recording devices or monitors that accept AHD or CVBS inputs Works with standard coaxial cabling used in CCTV deployments Designed for integration into existing analog or hybrid camera systems where mixing AHD and CVBS is required Practical use scenarios Retail store monitoring: Combine older analog cameras with 1080P AHD cameras to centralize feeds for a single monitor or recorder while replacing cameras as needed without downtime. Remote property or perimeter surveillance: Run coaxial cable up to 400M to cover outdoor areas or distant buildings while preserving video quality. Temporary or event surveillance: Deploy a fourchannel setup for shortterm installations or events where quick camera changes and reliable 12V power are required. Why choose this multiplexer This unit provides a practical, nononsense way to manage four analog and AHD camera feeds with hot swap convenience, 1080P support, and extended coax transmission. It is suitable for installers and system integrators who need straightforward compatibility and serviceable operation in mixed camera environments.
