Digital Key is a device that integrates and supports communication between the already existing opening mechanism in a door and our mobile that acts as a remote control. Digital Key can coexist with conventional controls, not invalidating them. The device communicates with Bluetooh technology. Digital Key requires electrical power, and is available in 230VAC and 12-24V depending on installation requirements. The APP is managed by an administrator (the person who registers the device at the time of installation), granting permissions to other users.
