I've recently switched from ring and tried setting up my doorbells activity zone to cover just my drive and not capture traffic on the road. I've tried this both as basically and as elaborately as I can to cover just my drive, however it captures random road movement (even well outside the activity zone) but not someone walking directly past the doorbell! There must be something I'm missing but I'm not sure what! I've turned sensitivity right down and right up, turned off vehicle detection but then it just triggers as movement! 
Please help, it's driving me crazy notifying me about random cars but not people stood at my door!!
