When troubleshooting video issues it maybe necessary to test video from the camera via UDP. Most VMS's offer ability to change the streaming protocol between TCP and UDP.
Using VLC you can request the video from the camera via UDP following the instructions below.
- Run VLC and go to Tools > Preferences (Ctrl + P)
- From the bottom, change Show settings from Simple to All
- Go to Input / Codecs > Demuxers > RTP/RTSP
- Uncheck Use RTP over RTSP (TCP) - this will set VLC to use UDP for streaming video.
Now you may enter the URL for streaming video from the camera as per usual.
