New to the form (and CCTV

I installed this camera and its detected as "FOSCAM | FI86xx/98xx compat.", but the sub-stream is not detected. Went to the CTRONICS site, but can't find anything on the sub-stream.
Also below on the "Network IP camera configuration" page, it says "ONVIF Source". Checked the manual but it's unclear what this is used for. Anyone?
Whats the best way to figure this out?
