About the VNR 100 Recorder

The VNR 100 recorder is a network appliance capable of recording PURE3 video, audio,
and data streams from VN-Matrix codecs and encoders. Multiple VNR 100 units can be
configured together into systems to record and play back multiple, synchronized PURE3
streams.
The recorder is able to play and control a previously recorded file while simultaneously
recording a new file, with a sustained aggregate bit rate of 150 Mbps. The VNR 100 is also
able to replay, with time slip, a file that is still being recorded.
One or more VNR 100 recorders can be used in a VN-Matrix system. The system must
be under the control of an Extron VNM Enterprise Controller, whether the system contains
a single VNR 100 recorder or multiple recorders. Controlling multiple recorder devices or
channels from a single master unit allows:
•
•
Multi-channel systems are facilitated by maintaining full stream synchronization of multiple
recorder devices across all stream elements (video, audio, data, and whiteboard) at all
playback speeds in forward and reverse directions.
The recorder uses a network storage architecture, which makes the system highly scalable
and flexible.
