ZeeVee HDB2840-NA HD Video Encoder / QAM Modulator with 4 HDMI Inputs Up to 1080i/1080p

Designed for control rooms, digital signage headends and security deployments, the ZeeVee HDB2840-NA HD video encoder / QAM modulator simplifies multi-source HDMI distribution so you can monitor and deliver consistent video across your network. This Pro AV switch-class encoder accepts four HDMI inputs supporting up to 1080i/1080p and converts them to MPEG-2 QAM RF output for delivery over coax or cable infrastructure. Built-in flexibility includes embedded digital or analog audio and a delay-matched analog output to ensure audio/video sync—critical for surveillance review and live monitoring. Closed captions are supported via composite input for accessibility, while rack-mount hardware and a 5-year limited warranty make the unit suited for continuous, mission-critical operation. Whether you’re upgrading a security monitoring room, deploying distributed digital signage, or integrating with an existing cable headend, the ZeeVee HDB2840-NA delivers predictable, low-maintenance performance.
