Crown Plus is a smart door lock equipped with a camera which can record videos and unusual incidents at the front door. The lock offers a range of access options to cater for different lifestyles including fingerprint recognition, NFC, password or card. Together with the Wulian Smart Home app it also allows for bidirectional communication with visitors. Moreover, it can also be linked to an existing smart home system – a simple touch on the screen is enough to activate the “home scene”.
