Access Control: An Introduction To Access Control
The Problem
Your building is secure at night, but during the day there are several doors that have to be open. Anybody could walk in. What can you do?
The Solution
You need an Access Control System.
What is an Access Control System?
Access Control is an electronic security system which permits or restricts access to specific areas of a premises. It not only protects property against unwanted visitors but ensures the safety of both the property and of the people inside.
In simple terms, an Access Control System provides control of entry (or exit) through nominated doors via a control panel and some form of electric locking facility.
An Access Control System can be as simple or as complicated as you wish but in each case, the solution will always provide an easy passage for permitted persons around the building.
Door Entry or Access Control?
Door entry is commonly associated with a single door or gate, whereas access control is more suited to multiple doors or entry points.
Access Control can also incorporate a host of other features which enhance other areas of the business.
Access Control / Door Entry Technology
There are a number of ways that a permitted user can open a door that is fitted with a system.
PIN Code Entry
The most common unit is the keypad system. This comprises a control unit with a series of numbered push buttons, or a touch-sensitive pad, connected to the lock release mechanism via a control unit located at the entrance.
Magstripe (also called Swipe Card) Readers
Each entry point has a card reader and the user “swipes” an encoded card similar to a credit card to gain entry.
This technology is widely used and there are many choices of manufacturers.
Proximity Readers
Rather than swiping the card or tag, it is simply presented to a reader which typically will see the card at a distance of about 100mm. This is a fast, non-contact, method of entry.
