So you want to take your door intercom to the next level? DoorBuzzing happens to be an interesting system that answers the phone when you have a new visitor and opens your door automatically during business hours. It can also ask for a pin, call backup contacts, and even send SMS alerts. You don’t need an additional piece of hardware to start using this solution.
DoorBuzzing notifies you when a PIN code is used. It also stores entry logs. It lets you forward calls to multiple people or your emergency contacts during outages. You can find out more about this solution here.
