Smart locks work by using wireless technology, such as Bluetooth or Wi-Fi, to communicate with a user’s smartphone or other authorized devices. This allows the user to remotely lock or unlock their door, monitor access, and receive notifications on their phone. Some smart locks also offer features such as voice control, geofencing, and time-based access.
In addition to wireless communication, most smart door locks use various means of biometric authentication, such as a password, fingerprint, or facial recognition, to ensure only authorized individuals can gain access to the lock. Some locks can also integrate with other smart home devices, such as security cameras or thermostats, to offer a more comprehensive home automation solution.
