There are generally two ways to support event notification, as defined in ONVIF spec
- Basic notification
- Pull-point style notification
Due to the reasons stated here, Genius Vision NVR does not support basic notification. So you should use pull-point style notification only, in order to pass our verification.
P.S. According to the spec, there is actually a third way to support event notification using RTP, but since we haven't seen any vendor has supported it, we won't be able to support it.
