NVS-25 is a small, easy-to-use video streaming and recording appliance designed for professional video producers who need to simultaneously stream a live event and record the master quality version for post-event editing.

From any HDMI / SDI / CVBS input source such as a camera or switcher, NVS-25 generates an H.264-encoded stream compliant with RTSP / RTMP / HLS protocols.

NVS-25 can be used in recording mode to record an MP4 or .TS file to a USB storage device, and it can be used in encoding mode to generate an H.264 stream.

NVS-25 is remotely controlled using Windows / Apple PC or mobile device with a web browser.

Flexible mechanism design for desktop application or 1U rack mount application.
