ONVIF Analytics

I wanted to explore more features of my webcam (TV-IP311PI). Apart from probing and streaming it can also do “video analytics”. That is the ONVIF name for motion detection.

From a system architecture point of view, it makes more sense to have each camera analyse its own view field and only then send image data. If we have a central system analysing data from many  cameras the data volume is much larger. Obviously the central system needs to receive image streams from all cameras in order to analyse them.
