About Us

CellNock® was conceived in 2007, and a patent was filed in April of 2010. The whole concept was to add convenience and privacy to any home or business by installing a device on your front door or entrance that would alert you by cell phone when a visitor pushes a button on the doorbell or peep hole unit. This would allow you to see and talk to the visitor without opening your door no matter where you are, even if you are not at home.
