Motion Sensor Triggering flase

@ zeustech possible, as same with direct sunlight. Suggest you do a Google site search on the forums and read up about it as there have been many threads on this topic in the past.

and then continue just changing the end of the search.  You can also call Support for assistance.

Maybe, it's sometimes a bit tricky to know for sure what trips its trigger, so to speak.

I'd suggest setting the motion sensor to Alert Only, then see how it goes for a while. If you get nuisance alerts you can change the location/position/sensitivity.

Just be aware that in Alert Only you get alerts even when the system is "Off" / disarmed. So, if you are in the room and moving about you're going to (or should, anyway) get those notifications.
