Access control is the ability to permit or deny the use of a particular resource by a particular entity. Access control mechanisms can be used in managing physical resources such as a door or a gate, which only certain users should be able to access.

There is a wide variety of access control devices, some are more familiar like an Intercom systems or magnetic cards and other, more complex devices include Biometric Fingerprint and Iris Recognition devices.

When a credential is presented to a reader, the reader sends the credential’s information, usually a number, to a control panel, a highly reliable processor. The control panel compares the credential’s number to an access control list, grants or denies the presented request, and sends a transaction log to a database.

When access is denied based on the access control list, the door remains locked. If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the door. The control panel also ignores a door open signal to prevent an alarm. Often the reader provides feedback, such as a flashing red LED for an access denied and a flashing green LED for an access granted.

As a leading Access control System integrators, we install regularly the following systems:

1) Proximity Cards
2) Fingerprints systems
3) Iris Recognition systems
