Currently no, because virtually no normal IP camera supports this. If this becomes a more widely-used standard in the CCTV world in the future, we will certainly look at supporting it.
Thanks. Given that I can receive NDI into OBS can you suggest a way I could re-stream it out of OBS in a format that SS can understand e.g. OBS supports RTMP
SecuritySpy can received RTSP streams (this is the standard for IP cameras). So if OBS can produce an RTSP stream then you should be able to get this into SecuritySpy, using the "Manual" profile under Preferences > Cameras > Device, with the "RTSP" Format option selected, and the correct "Request" entered (taken from the RTSP URL in the form rtsp://address/request).
