ONVIF motion events notifications to NVR

[mattj]

Does anyone know if there are plans to add support for motion event notifications from ONVIF compliant IP cameras? The benefit would be that the cameras handle the work of motion detection, unloading the NVR. Very high res ONVIF cameras are cheap now ($125/ea for 1920p resolution) so this would be a great feature to have.

This guy seems to have figured out how to do it, though I haven't been able to find a copy of his script:

Thank you! This made my day. Do you know off-hand if code changes and a re-compile to ZM are necessary to make it work with this perl script?

I have an ONVIF camera coming this weekend and I'm going to try to figure out how to get this working. I'm technical, but brand new to ZM and not yet familiar with how to integrate add-ons like this.

The fact that this script is not yet in ZM master and is in the author's tree may imply its not fully operational and/or may have gotchas. You may want to directly ask the author.

In general, it looks like this script is registering with the available ONVIF cameras ZoneMinder discovered and is waiting for motion events. If they are received, the author is passing them on to ZM's existing trigger mechanism to start recording. Such operations don't need ZM to be recompiled (see here for a basic tutorial I wrote a long time ago about how ZM triggers work and how your "script" can attach to it, in this case this onvif trigger)
- but I have no idea if this codebase expects certain ONVIF functions in ZM that are not in ZM master.

Thank you very much for the information and the link! I actually stumbled on your pages from the link in your signature and started reading through it, you've got some great info there. I'll dig into it more tonight after work.

I'll upgrade my current 1.29 to 1.30 to get a build with ONVIF features turned on, then see if I can get the script to work. I'm guessing I just execute the script manually after ZM is running? I'm trying to learn as much as I can, maybe I can contribute somehow if I can get it working with the cameras that I ordered.

I sent a note to the author through his wordpress blog, hopefully he will respond.

Thanks again!

This thread is very interesting. I just started with adding ip cameras (ONVIF compliant) to my zoneminder system. If the cameras can somehow push motion detection events to zoneminder (instead of zoneminder doing the calcs for modect), it would be excellent.

mattj, I dont think just running the script will do it. If you read through the two articles on Jan's site titled ONVIF Analytics and ONVIF Notifications, you will see that the script is just one part of the bigger picture. Unfortunately, there is no information yet on how to actually implement this. Hopefully, Jan will post more details on this soon.

Has anyone seen http://zgtk9jlvq.xiagao.us/2014/11/24/1 ... 07267.html. The author claims he/she got zoneminder triigers working with ONVIF video analytics as far back as nov 24, 2014. It does not give any details and text in the page is oddly truncated.

That http link you posted is a little weird.
Here is the actual page, from the original author's site:

The ONVIF probe currently in zoneminder 1.30.0 is a result of alatroca's work. I guess it was a different thread where I stated she has mentioned integrating her work on detecting motion events through onvif in a future pull request. If you want to contribute then the best way to do that currently would be through her blog site.

Well, I feel embarrassed. Apparently, Jan is a guy, not a gal.

Yes, the link seems to be copy of Jan's wordpress blog.

I am a little confused by the current state of ONVIF support in 1.30. Jan says that he has gotten ONVIF probing, video analytics (motion detection) and notification to work but we have to build from his repo to get all this. So where do we stand in the 1.3 release as far as these 3 features are concerned?

[knight-of-ni]

@Khurram See the 1.30.0 release notes

@Khurram See the 1.30.0 release notes

I checked the release notes and I see that ONVIF probing is there, but there is no mention of video analytics or notifications. So I guess these 2 features have not yet made it into the release. Am I right?

I was wondering when you'd figure it out

I had to give him a hint.

I'm still wondering if Jan is a guy's name only in Germany, or if I am just a dumb American. I suspect the latter. I guess I need to travel more.
