For the doorbel camera… I have an American Flag on my front porch that waves around in the breezes and will surely set of the alarm doorbell constantly…is there a way to create a sensor zone so the flag does not set off the motion alarm
There no a zone area u can set up but most likely it will set ur doorbell off a lot
Put a Canadian flag 
Probably the new doorbell with the analytics will be able to help with this.
The new Alarm.com ADC-VDB770 uses video analytics, allowing you to specify a ground area for object/person detection. The flag area can be ignored.
