Very cool. I do a similar "fail safe" strategy too. Here's the layout of my tripwires - click for larger view

I would love to be able to have a zone crossing setup like yours. Even a simple one that works would make my day. I have been using BI for many years with great success on this pretty robust system. Everything is up to date. I am not presently using AI but I have successfully used just about every feature offered with the exception of one; I have never been able to get a simple AB or A>B Motion Crossing to trigger a recording.

I have my over all 'A mask' (as you have in your image) and then added my 'B' & 'C' masks using the BC or B>C command in the Object Detection window (I've tried it both ways). This is on my driveway so my goal was to have an automobile approach and span 'B' while then entering 'C' which in my mind should trigger the alert and record, but it does not. It triggers the little 'motion' alert icon but not the one for 'record'.

I can trigger a recording if I have just one simple zone on the driveway but I need a 2-zone crossing setup to minimize triggers from deer and the occasional moose. Yup! My idea was this: If I have an overall zone 'A' and then 2 more zones (B&C), and they are spaced approximately 10 ft. apart, a car should be able to cover most of the B&C zones simultaneously and trigger the recording, whereas a deer would not be large enough to span both zones and would not cause an trigger. I also have tried this with the zones almost touching and also with them overlapped. I have my 'Object Crosses Zones' checked and have tried with 'Object Travels'" checked and unchecked, same with 'Black & White' and 'Method: Simple', etc. I have rebooted and redrawn my zones. Deleted the camera a started over, etc. Still no good. Can anyone suggest anything that I may be missing here? Sorry this got so long.

Could you post a screen shot of your driveway?
