How does the interaction between a Milesight camera and higher layers of the system work for the advanced VCA functions (Camera <- -> NVR and VMS)? The camera has various options for VCA actions, e.g. local recording to SD card etc. There is also the HTTP notification that is so far the only method for interaction I have seen. However, I have not yet found a counterpart in the settings of the NVR. The NVR has settings for the basic motion detection but how to access the advanced VCA from NVR? How about the security in using the HTTP notification? The protocol seems to transfer also username and password. One nice feature of Milesight NVR is the ability to use simultaneously both continuous recording and motion detection based recording in the timeline. It would be really nice to see also the advanced VCA findings there.
