Additional snooze option

Anyway having the wireless door sensor or a optional wireless button made so it snoozes like the doorbell when someone goes outside to sit for bathroom break for dogs or a smoke break so it snoozes automatically when door contact open or push of a button like from smartthings?

You can do most of that with the keypad. Set up a custom mode that turns off what you want and then hit that Cus button on your way out. You will have to hit the Home button when you come back instead of having it turn on at the end of some interval, but its doable.

Would that include specific cameras associated with the home base or would it be all that are associated with that base station?
