ONVIF Notifications and ZoneMinder

ONVIF triggers external events in ZoneMinder

I finally put together everything I had learned about ZoneMinder external event triggering and ONVIF VideoAnalytics.

The result is a script zmonvif-trigger.pl that subscribes to events from several ONVIF cameras. The cameras send these events if something moves in their view field.

On reception of an ONVIF event the script generates a ZoneMinder event. Thus the ZoneMinder server does not need to analyze the video streams from several cameras. The cameras themselves watch for any movement. This saves a lot of CPU power and network bandwidth.
