H.264 Video Streaming Server / Recorder

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.

I bought the NVS-25 for an educational conference. We streamed to YouTube for 3 straight days without a hick-up. I made sure it had the latest firmware which apparently fixed many previous issues. A great streaming tool.

We bought the NVS-25 to stream our seminars. It was easy to set up and use. I watched the video tutorial that Datavideo made, which helped me through the set up part. I like the simple push of a button to stream and record.

I tested the [NVS-25] this evening with a 1 hour 40 minute stream and recording at the same time. Both seemed to work well :)
