Cerberus is a wireless system designed to allow the owner to view visitors and allow them to enter without the need to be present. Using a security system, the owner is able to log into the server either on the website or Android application to view the status of the system. Upon a visitor knocking on the door, the user is prompted and can either send messages to the visitor or allow them to unlock the door using either a secret knock or keypad code. A motor operated mechanism then turns the lock in either direction to allow or deny access.
