Access control gives you control over who has access to your building.
There are different types of units that do this.

One of the most common types of units is the keypad system, comprising a user terminal with a series of numbered push buttons, or a touch sensitive pad, connected to the lock release mechanism via a control unit inside the entrance.

For added security, card entry units allow access when a pre-programmed card is introduced to the terminal and these are generally more secure, essentially because they require the physical possession of an appropriate card or fob.

Door access applications:

• Controlling access and movement in offices and factories
• Screening access to high value retail outlets
• Securing residential apartments
• Tracking movements of staff and visitors within your premises
• Controlling access to car parks, operating barriers or gates
• Visual and audio verification of visitors (commercial or domestic)

PL Systems specialises in the latest growing category of door access, which are proximity systems, so called because they unlock the door when a token is placed near the terminal.

This type of system which can be PC based fulfils additional needs, such as recording arrivals and departures for payroll purposes, finding out who is where in a fire or other emergency, or discovering who went where, when and for how long for investigative purposes. All tend to integrate well with other security measures such as closed-circuit television.
