What is an encryption lock?

The lock refers to a number of door security devices. While there are combined locks, intelligent card locks and key locks, the mechanism known as the cipher lock is open by a programmable keyboard and - by definition - is not a real lock. There is also a specific type of cipher lock called Cypher Lock®, which was developed by Continental Instruments, now the Napco security group.

The US Army distinguishes the use of encrypted locks and key locks and states that the purpose of key locks is to maintain physical safety, while the purpose of cipher locks is to control access, reduce incapable disruption or undeserved entry into specific areas of equipment that are sensitive. Cipher locks are used to manage access to areas such as airport towers, computer rooms, corporate offices, embassies, areas of financial institutions, research and development laboratories and storage areas that hold weapons, etc.

It can have four or five buttons, depending on the manufacturer. Even with five buttons, the code can be on one to five digits. After setting the cipher unit, the code is programmed and shared with authorized staff. It can be changed at any time.

Cipher Locks are available in various metal colors and can be equipped with either a button or a lever. The system can be mechanical, as is the case with Simplex or electronic lock locks, as well as Cypher Lock®. The electronic system allows you to unlock the door from the room in the room when a visitor who has no code arrives.

especially Cypher Lock® can be combined with a set time to open doors and battery standby. There are three types of alarm system. There is an interface of the alarm of burglary, which indicates when the door of the break is. Alarm errors can reveal someone who is trying to guess the code. Eventually can be SPSnked hostage alarm, which indicates that the input was under pressure.
