In Access Control System, when a credential is presented to a reader, the reader sends the credential’s information (usually a number) to a control panel, through a highly reliable processor. The controller then compares the credential's number to the pre-assigned access group and then grants/denies access based on the presented request by sending a transaction log to a database.
When an access is denied based on the access group, the door remains locked. If there is a match between the credential and the access group, the controller operates a relay that in turn unlocks the door.
SSI iSecure access control application has the SMS control facility to inform to the authorized person immediately about proxy punching if, an unauthorized person or unknown credential is presented to a reader.
Also SSI iSecure Access Control application has the facility to open all doors as well as particular door in case of emergency from remote location through single SMS if the authorized person is out of company premises.
