It offers multiple ways to unlock and is built with a zinc alloy material for durability. 

Key features

The Dahua DH-ASL7112R provides a range of security and convenience features: 

• Multiple access methods: You can unlock the door using a Mifare 1 card, a password, a fingerprint, or a traditional emergency key.
• Privacy protection: The anti-peeping password feature allows you to input extra random numbers before or after your actual password, preventing others from observing your code.
• Mode selection: The lock includes different operational modes, such as "Passage Mode" for free entry and exit without needing a password and "Non-disturbance Mode," which only allows an administrator to unlock the door.
• Auto-lock: The system automatically locks after a series of failed attempts to enter a password, card, or fingerprint.
• Low power alert: The lock notifies you when the battery power is low (below 4.5V) so you can replace the batteries.
• Emergency power: If the batteries die, the lock has an external emergency power supply option, typically a 9V battery.
• High capacity: The lock can store a large number of access credentials, including up to 100 cards, 100 passwords, and 100 fingerprints.
