The induction door lock is a kind of door lock that can be sensed by ultraviolet or infrared rays. This kind of door lock can achieve the effect of opening and closing the door through these hurriedly. The anti-theft effect of the induction door lock is relatively strong, because this kind of door lock is similar to the fingerprint lock, and the induction door lock will remember a certain kind of ultraviolet or infrared to realize the opening and closing of the door.

The door lock circuit board is made of three-proof treatment according to military standards, which is anti-corrosion and durable. The lock core of the door lock adopts a five-bolt structure, which is anti-insertion, and is safer.
It has a completely independent mechanical emergency unlocking mechanism. The emergency unlocking mechanism and the electronic unlocking mechanism adopt two completely independent transmission devices, which greatly improves the reliability of the door lock.
The open interface facilitates the connection with the hotel management system software and provides hardware card reading equipment to realize the all-in-one card.
