Qumulex will connect and stream video from any Costar/Arecont that supports ONVIF Profile S.
However, the modern ONVIF method for getting events from cameras (using PullPoint) is not supported in any of the older series, Megaline Arecont cameras. The only cameras, per Costar/Arecont, that support Pullpoint are devices in the Contera line.
What this means is we can connect and record Continuous for Megaline cameras, but motion detection and any other event generation are not in a format we can use. So it will be continuous only.
