Network Video Decoder Matrices

Every camera. Every screen. Always on.

IP cameras → decode → surveillance wall

  • Decode up to 32×1080P or 4K/8MP streams per card
  • H.265 / H.264 with ONVIF / RTSP / GB28181
  • 1U / 3U / 5U chassis scales with your camera count
Overview

Engineered for reliability

Decode large numbers of IP camera streams — H.265 / H.264 / MPEG4 with ONVIF / RTSP / RTMP support — and display them on a surveillance wall. Rack-mount chassis with decoder cards scale from compact 1U to 5U systems, with 4K/8MP decoding, web control, scene presets and multi-unit cascade.

Every bundle is confirmed by an engineer against your signal list before any quote.

Configure your bundle
Right for you if…
  • IP camera walls from H.265 / H.264 / ONVIF / RTSP streams
  • High split density per screen (up to 25 windows per output)
  • Multi-subnet decoding and cascading across sites
Not the right fit if…
  • Local HDMI signal routing — a matrix is the right tool
  • Stitching of non-IP sources — use a processor
