I will surely play around with this option
CPU sounds right, but used memory seems low. Maybe I run a poorly configured Win10 but I couldn’t imagine a plain install of win10 alone using that little memory. I’ll check at home, but my work computer has soaked up 10GB for just outlook and some spreadsheets.
10 GB seems ridiculous much to me.
True, Rectangles won’t help you know what isn’t triggered, but it does to help know how it is being triggered.
Yeah right, that's also true. I think most missed triggers were caused by focussing to much at size and contrast, and less at travel distance. Imagining what is about 100 pixels for that certain camera, makes you realize some motion can easily stay within that radius, within the make time. Also I had the wrong perception of the word 'object'. It made me think of cars and other large stuff, rather than just a person walking by. So, there was less awareness of the relevance of these settings, concerning missed motions of people.
As for TimG’s comment that there are tons of options and easy to get it messed up, you can create a new camera using an existing used video source to “start over” on the settings and see if that helps. The JesseWeb link above does well to describe a basic and optimized camera configuration.
I'll keep that in mind.
