About the VNM Recorder
The VNM Recorder connects to a network and is used to digitally record and play back
multiple PURE3
®
streams via the IP network of VN‑Matrix encoders and decoders. The
VNM Recorder is used with any VN‑Matrix application to document, archive, review, and
play back highly sophisticated or demanding AV imagery.
The VNM Recorder has the ability to record PURE3 encoded IP streams on each channel.
Up to five PURE3 streams can be recorded or played back on a single recorder. PURE3
streams recorded together maintain proper synchronization on playback.
The VNM Recorder uses a network storage architecture which makes systems highly
scalable and flexible. Storage capacity can be increased or decreased based on the number
of inputs, recording time, and archiving requirements.
