How secure would an office premises, or industrial warehouse facility feel if one was able to facilitate an automated approval for strictly authorised individuals to enter, via a security portal, without the need of a physical security guard present? Incredibly secure, and it’s possible if you install a security access control system.

Access control systems are a set of electronic networks that restrict the access to security portals. A security portal is an entry into or out of a security boundary. It can function as an intrusion alarm system, and consists of field equipment, decision modules, a communications network, one or more databases, and one or more computer workstations.

From a common pedestrian’s point of view, an access control system typically includes a door, a credential reader (like a card or a buzzer in an apartment), an electronically-controlled door lock, a door position switch and a request-to-exit sensor.
