Missing motion capture

Similar to a few other posters, outdoor stick up captures some arrivals and exits, but rarely both, even on the same route. I have seen dustbin on driveway, next thing it's empty and on the road, but no sign of bin lorry in either direction. Cars can drive up to house and park and suddenly are just there on the event, but no approach. Cars passing the house are all picked up. Postman can walk up and get captured, but not on exit, or vice verse and uses the same path! Can't see me signing up for this Ring Protect Scam if half the stuff is not recorded. Will be returning before the 30 day trial runs out at this stage. Have tried moving and changing angle, but I don't understand how walking in one direction is different to walking in the other!
