Access Control Systems

Types of Access Control

PC Based:

A PC based access control system, gives you complete control over who gains access to your business or site. The key benefits of centrally controlled PC based access system are:

  • Central Control - All doors can be controlled from one place.
  • Reporting - An event is generated every time a token is used to gain access.
  • Complete flexibility - Access can be granted to users according to time and place.
  • Remote Sites - everything can be controlled on a remote site in exactly the same way as at your Head Office.
  • Roll call & muster reporting - is a means of checking staff at a central point if an alarm activation requires the evacuation of a building.
  • Time sheet for time and attendance - shows the number of hours worked by each employee. Check at a glance, who is in who is out.

Intercom Based

Have control over who gains access with an intercom entry system.

Integrated audio, video or telephone based door-entry systems enable you to monitor and control visitor access into any premises – a door entry system can be interfaced to work with gates / barrier automation and other associated access control systems.

Systems can range from the simple one way analogue telephone entry, typically seen on residential and small commercial buildings comprising of a door panel, lock release and handset, to the far more sophisticated digital systems including Multi-way Video and audio systems, or remote access systems used for large commercial premises or blocks of apartments.

Audio Entry Intercom Systems:


Audio Entry Systems provide audio communication between the protected and unprotected side of an entrance, allowing you to verify the identity of a caller before granting access. Access is usually achieved by triggering a lock release or similar locking mechanism by simply pushing a button located on the receiving handset. This type of system would normally incorporate a door station and an internal phone style handset.

Video Entry Intercom Systems:


The video door entry system is the same as the audio door entry system but includes the added benefit of providing live video at the door station. The video telephone allows the resident to view callers at the entrance, speak with them and then grant access, which would be achieved by triggering a lock release or similar locking mechanism on the telephone handset. This system would be the same as that used for the Audio system but will include a small camera built in to the door station and a small 4” monitor in the telephone handset.

Telephone Based Intercom Systems:


Some larger sites, especially those which are monitored from a central station, would utilise a telephone based entry system. These systems would usually be installed in conjunction with other security products, but can also form part of a stand-alone system. These systems would be linked to a standard telephone line or PABX system, when the button is pressed the unit will dial a pre-programmed number. Upon answering the phone, audible communication can be held between the door station and telephone. Access can then be granted by pressing a pre-programmed button on the telephone handset. This type of system could be used for commercial properties requiring controlled access for out of hours deliveries.
