I get constant motion detection notifications when it's dark because of the location of my front door.  When the headlights from cars entering the neighborhood hit to doorbell, it sets of an alert.  I've set the sensitiviny down to 1 and set the detection zones to only include the concreted of the porch, but it still goes off.  I've had to turn motion detection off and rely on person detection only.  I understand that there may be a hardware limitation to filtering out headlights from setting off detection, but how about having the ability to turn motion detection on automatically during certain hours, or perhaps have a setting where it turns off automatically when it gets dark?
