How it compares

Take Submarine over the D-series face locks when the door is exposed to weather. The D-series is specified for sheltered residential entrances; Submarine trades the video doorbell for an IP68 sealed body.

Installation and use

Set the door opening direction in the lock system at commissioning. Enrol main users first, then standard and time-limited users, so the hierarchy is correct from day one. Press the doorbell key on the lock to send a visitor image to the app.
