Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock device installed on a door of a condominium, a general house, an office, a shopping district, and the like. The present invention relates to a wireless door lock in which a transmitter can be used to easily open and close the door, and at the same time, a security and alarm device is attached to greatly improve the security.

[0002]

2. Description of the Related Art Most conventional door locks use a metal key and require a key insertion port exposed to the outside. Therefore, a so-called universal key is sometimes used to intrude into the exposed key insertion opening without permission, so that the security is deteriorated, and foreign matter may be forcibly inserted or damaged by an unreasonable operation.

[0003] On the other hand, without a key, the fingerprints and pupil characteristics that make the best use of the individual differences of the entrance and exit are recognized, and if they match, the entrance / exit door opens or closes, or the door lock is equipped with a keypad, and the secret code is input. There is also a door lock that opens and closes the entrance door if they match. Since these door locks do not carry or use the key, there is no need for a key insertion port, there is no need for imitation or copying of the key, security is improved, and it is also necessary to copy as many keys as the number of authorized visitors. There are advantages such as no.
However, the structure is complicated and expensive, there is a high risk of malfunction, and there are drawbacks such that unauthorized persons who are not registered cannot enter or leave alone. Some door locks have a keypad, but since the keypad is exposed to the outside, there is a risk of damage and unauthorized operation by an intruder. There is also a problem of lack of security. If there is a slot on the front door where milk, newspapers, etc. can be thrown in, there is also a problem that a tool is thrown in through the slot to operate the locking device to open the door.

[0004]
