Access Control & Entrance Security Systems

Access Control & Entrance Security Systems

Physical access control is a matter of whom, where and when. Access control systems determine who is allowed to enter or exit, where they are allowed to exit or enter and when they are allowed to enter or exit. Historically, this was partially accomplished through keys and locks. When a door is locked only someone with a key can enter and/ or exit through the door depending on how the lock is configured. Mechanical locks and keys generally do not allow restriction of the key holder to specific times or dates. Mechanical locks and keys do not provide records of the key used on any specific door and the keys can be exactly copied or transferred to an authorized person. When a mechanical key is lost or the key holder is no longer authorized to use the protected area, the locks must BE physically changed.

Electronic access control uses the power of computers to solve the limitations of mechanical locks and keys. The electronic system determines whether to grant access to the protected area based on the credential presented and when it is presented. If access is granted, the door is unlocked for a predetermined time period and the transaction is recorded. If access is refused, the door remains locked and the attempted access is recorded.

The system will also monitor the door and declare an alarm if the door is forced open or held open too long after being unlocked the door remains locked and the attempted access is recorded.
