Electronic Access Control
Progression from mechanical locks to electronic locking systems can be from simple keypads through to biometric recognition.
Keypad Systems work on the basis that a four-digit code is entered which, if correct, will unlock the door. These systems are usually used on low security doors.
The next progression is to stand alone Proximity Based Systems which use a unique proximity device for each user; this can be in the form of a token, card or key fob. These systems are for higher security doors and doors that need more control of entry.
These systems then progress on to Full Networked Systems which also use proximity devices, but can use code as well as proximity for higher security, where the user needs both to gain access. They also offer timed entry to buildings to control when access can be gained, and provide a full audit trail of access through all doors, by which user, and at the exact time. These systems are for higher security sites or where full system control and auditability are required.
Biometric Systems can be one door systems or fully networked systems.
Readers range from basic fingerprint readers, to full hand readers, through to iris recognition.
These are for high security sites where total lock-down is required, such as laboratories, power stations, banks or government offices.
