Motion detection trigger by camera, not by camera.ui
I am using camera.ui since da few days, seems to work fine. Great Plugin!

Before I used a Synology NAS with Surveillance Station. In Surveillance Station I could configure motion detection by surveillance station OR by Camera. My Cameras (LevelOne FCS-3084) habe built-in Motion detection. In Surveillance Station, the cams are conntected by ONVIF. I had nothing more to configure, it just worked. When I used "Motion detection by surveillance station", I had the CPU always up on 100% and the LAN was on heayv traffic.

How do I have to configure Motion Detection by Camera?
