Smart Doorbell™

Smart Doorbell™

How can we make doorbells more interactive?

Traditional doorbells don’t allow a homeowner to remotely engage with those at their door, preventing communication with visitors or deliverers and risking the security of the home.

The Solution 

With the interactive system Smart Doorbell™, users receive real-time updates and can communicate directly with their visitors. 

A motion detector and humidity and temperature sensors recognize when a person has approached the door. The visitor’s face is photographed and they are given an option to send a voice message to the user. The user can decide to respond with a predesigned template message or customized voice or text message. Visitor photographs and messages are saved in a log, so users have a recorded history of who came to their door.
