that is designed to perform locking and unlocking operations on a door when it receives a prompt via an electronic keypad, biometric sensor, access card, Bluetooth, or Wi-FI from a registered mobile device. These locks are called smart locks because they use advanced technology and Internet communication to enable easier access for users and enhanced security from intruders. The main components of a smart lock include the physical lock, the key (which can be electronic, digitally encrypted, or a virtual key to provide keyless entry), a secure Bluetooth or Wi-Fi connection, and a management mobile app. Smart locks may also monitor access and send alerts in response to the different events it monitors as well as other critical events related to the status of the device.

Some smart locks work with a smart doorbell to allow the user to see who and when someone is at a door. Many smart locks now also feature biometric features, such as fingerprint sensors. Biometrics are becoming increasingly popular because they offer more security than passwords alone. This is because they use unique physical characteristics rather than stored information. Smart locks may use Bluetooth Low Energy and SSL to communicate, encrypting communications using 128/256-bit AES.

Industry smart lock

Industrial smart locks ( passive electronic lock) are a branch of the smart lock field. They are an iterative product of mechanical locks like smart locks. However, the application areas of industrial smart locks are not smart homes, but fields that have extremely high requirements for key management, such as communications, power utilities, water utilities, public safety, transportation, data centers, etc. Industry smart locks mainly have three components: locks and keys, and management systems. Similarly, the key is no longer a physical key, but a special electronic key. When unlocking, the unlocking authority needs to be assigned before. Through the management system, the administrator needs to set the user, unlock date and time period for the key. Whenever the user unlocks or locks the lock, the unlock record will be saved in the key. The unlocking record can be tracked through the management software. Industry smart lock cylinder

At the same time, industry smart locks can also remotely assign permissions through mobile app.

Security

Due to the inherent complexity of digital and wireless technologies, it can be difficult for the end user to confirm or refute the security claims of various product offerings on the market. The devices may also gather personal information; representations by the vendors involved concerning the care and handling of this information is also difficult to verify by the end user.
