External trigger (zmtrigger.pl) and object detection

Post by Norknie »

Hi,

I am Using zoneminder in docker.
For a while I successfully used MODECT combined with the object and face detection via zmeventnotification. This worked really fine but I had a lot of false alarm caused by insects or leaves.

Since I own a PIR Sensor, I want to use it as an external trigger to start capturing video frames and detecting objects in this video.
I am able to trigger capturing using zmtrigger and sending “ 2|on+20|1|External Motion|External Motion” via telnet. This works, videos gets captured.

Unfortunately there is no object or face detection any more when using external trigger. I suspect it may result from the high number of alarm frames with the same alarm score (since I only can send one score via telnet, see above). According to the logs frame_id=bestmatch will choose the alarm frame with the highes score. Since all alarm frames share the same score height, maybe it doesn’t work.

Do you have a recommendation what exactly to add to the config files to get object detection working again?

Thanks in advance

Nork
