The Door Keeper works like a smart doorman and turns existing door locks into active protection devices for the home. With an integrated lock-detection system and an intrusion sensor, the smart, motorised lock permanently monitors the front door and triggers an alarm as soon as vibrations indicate an attempted forced entry. Elegant and ergonomic in its aluminium design, Door Keeper provides a reliable solution to protecting entrance doors without impacting function. The powerful motor is compatible with all common lock systems and is easy to operate with the Somfy Keys app.
