The Ezviz DL01S smart door lock in a modern gray-black design perfectly secures the entrance and allows you to unlock or lock the door with just a click in the mobile application. Another option is to enter a security code or attach a contactless card to the DL01CP wireless keyboard, which is included in the package. The keyboard is waterproof according to IP56 and in the event of an attempt to remove it, it triggers a loud alarm. It is also equipped with a middle button with a bell function, after pressing which the smart lock inside will start ringing. The combination with the supplied EZVIZ A3 smart gate brings a wide range of options and functions, including remote access from anywhere, automatic locking, generating a temporary key for guests, managing users or sending notifications in case of unlocking. Connecting the gateway to the Internet can be easily implemented both by wire via an RJ-45 connector and wirelessly via Wi-Fi. The device is installed directly on the original lock with the key inserted, no intervention in the lock mechanism is necessary. After that, the key is turned automatically, but if necessary, the lock can be unlocked manually using a button. From the outside, it looks like a completely ordinary lock and can be unlocked with a key. The lock communicates with the smartphone and keyboard wirelessly using Bluetooth. It uses Zigbee technology to connect to the EZVIZ A3 smart gate (included in the package) and subsequent integration into a smart home. Both the keyboard and the lock are powered by AA batteries.
