ONVIF camera support of VMS

We test several VMS to check which ONVIF functions are supported. The camera is AXIS P3301 with firmware version 5.40.9. The result is same as our ONVIF v2.2 for DM368.

Milestone XProtect Go is the leader. It support all the functions we listed. Most important, it supports motion detection and input port events well. Both exacqVision and Avigilon claim supporting ONVIF motion event but they are not working in our test. Maybe event topics used by P3301 are not recognized.
