@WJA96. I thought I had set the IVS settings correctly (with intrusion, drawing an area), I even selected 'object filter' 'effective object' = Human. However, I have just noticed that my alarm is going off whilst my boiler is running and causing small clouds of white smoke. I've just disabled my intrusion rule and enabled the smart motion detection again and its stopped causing that to go off.
Any advice?
P.S I noticed that before when I was testing the intrusion alarm, it would not always set the alarm off even though I was standing and moving inside the area that I drew. Is that normal? Perhaps the camera can't pick me up right at the edges of the drawn area?
