Access control systems are electronic systems used to limit and monitor who, when and where people access certain areas of a site. They can be as simple or as intelligent as required, and are operated via Analogue or IP networks.
Access control systems are widely used in applications such as apartment blocks, offices, colleges and government buildings. Systems can also be utilised on turnstiles, gates, barriers and automatic doors.
A system usually comprises of an electric lock attached to a door, with a reader or pin pad installed. When the correct card, fob, code or smart card is presented to the reader or keypad the intelligent system will check its database of programmed users, and if they are authorised it will grant access by releasing the lock.
