Access control systems are designed to permit the free flow of authorised movement into any site, whilst denying entry to unwanted visitors.

CAS offers a range of access control systems including swipe cards or pin codes, and proximity readers. Access control systems can be integrated into other systems in the building, such as time and attendance records, and CCTV Systems which will activate when a door is opened to provide usual proof of who is entering the building.

The access system can be integrated as part of a Building Automation System providing control over lighting, air conditioning etc.
