Access Control systems
Access Control provides the ability to control, monitor and
restrict the movement of people, assets or vehicles in, out and around a
building or site. Access Control provides ‘owners’ with the ability to protect
their people, assets and intellectual property. Unlike old-fashioned methods
such as a lock and key, Access Control provides not only security but also a
record of events that have occurred. It also offers the unique identification
of individuals or goods entering or leaving controlled zones within a building
Access Control should be considered wherever there is a need for restriction or control of access. Typical applications include: staff and visitor movement around an office building or site; the controlled movement of assets in, out and around a building. Examples include the entry of personnel into secure areas, the movement of patients, staff and/or visitors around a hospital, or the control of entry into car parks.
Product Options for Access Control
With continuing developments in technology, the variety of products for Access Control has improved to meet the specific needs of the market.
Access Control systems can function as stand alone or on-line systems connected to an operator station.
Products range from token-based systems, digital keypads, through to biometric identification systems.
The increasing complexity of security requirements and the improvement in flexible technology solutions available has led to the integration of
Control products with other security systems. Access Control systems offer
interfaces to Alarm Management, CCTV, Video Badging, Time & Attendance and
Building Management systems, amongst others.
Token-based systems offer solutions for applications including: building or site security, asset tracking, patient protection and vehicle identification. Available token technologies include: Proximity, Hands-Free, Magnetic (Stripe), Wiegand, Biometric, Smart Card or indeed a mixture of these, depending on the system requirements and capabilities.
In this case the token is simply a numeric code entered into a keypad on or near the door.
Codes can usually be set to different lengths and most keypads have the capacity for more than one code.
Biometric systems are used where the highest security is required, or specific personal identification is critical.
In these systems it is a particular aspect of the human physiology that is stored (eg voice, finger print, palm print, iris or retina), and this stored value is then compared against the person whenever access is requested.
Audio/Video Entry systems
Audio (Intercom) or Audio + Video combination arrangements may be deployed where human control of access is required from a remote control point.
are popular in receptionist or security guard environments, allowing direct
human control over entry to selected areas.
On-line systems generally provide real-time operator management facilities. Systems offer graphical and textual display facilities, allowing easy operator control. Multiple selectable reports are available to provide site managers with real-time as well as historical reports of chosen incidents. It is normal that multiple operator positions may be interconnected on industry standard local or wide area networks.
The growing nature of sophisticated Access Control systems make them ideal platforms for integrated systems, providing total security management, with CCTV management and video badging to allow the use of video verifications.
These may be provided on the same operator position as the primary access control function.
