Access Control System
From homes to factories and offices of any size, our access control/intrusion systems meet the most rigorous international standards and include the most advanced security technology. Typical products and systems includes access control readers, this includes; card, card and keypad, biometric, Card and Biometric, Iris/Face recognition Readers. Intrusion detectors/alarms, transmission equipment plus Local Security Network (LSN-Bus) equipment. We help organisations make sure they are not leaving themselves exposed to unnecessary and excessive business risk as well as the inevitable financial pitfalls.
Access Control System Operation
Credentials are something you have, such as an access badge or password, something you are, typically a biometric input. or your face. when this is presented to a reader, the reader sends the credential's information, usually a code, to a control panel, a highly reliable processor. The control panel compares the credential's code to its access control list, and grants or denies access base on the presented credential. When access is denied based on the access control list, the door remains locked. If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the door, also sends a transaction log to a database. . The control panel also ignores a door open signal to prevent an alarm. Often the reader provides feedback, such as a flashing red LED for an access denied and a flashing green LED for an access granted. The above description illustrates a single factor transaction. Credentials can be passed around, thus subverting the access control list. For example, Barrack has access rights to the server room but Tony does not. Barrack either gives Tony his credential or Tony takes it; he now has access to the server room. To prevent this, two-factor authentication can be used. In a two factor transaction, the presented credential and a second factor are needed for access to be granted. The second factor can be a PIN, a second credential, operator intervention, or a biometric input. Often the factors are characterized as
- something you have, such as an access badge or passcard,
- something you are, typically a biometric input.
Access Control Door Wiring
There are two options for connecting door hardware to the system:
Typical access control door wiring
- "Home run" (typical) configuration: non-intelligent readers that simply read card data are used, all components connect directly to a control panel. Advantages: since the interface between a control panel and a reader is standard, almost any type of reader may be used regardless of the identification technology or manufacturer. Disadvantages: generally there is more cabling to be done and the closet or cabinet containing the control panel may become jammed with cables coming from multiple doors; in case a control panel fails, all doors connected to that panel will be affected.
- Distributed configuration: All components connect directly to a reader,intelligent readers are used,. Advantages: there is less cabling work, maintenance and troubleshooting tasks are usually simpler; in case an intelligent reader fails, the problem is limited to just one door controlled by that reader. Disadvantages: Intelligent readers are usually bigger and more space is required behind the reader for connecting door hardware components; selection of intelligent readers is not as wide as selection of non-intelligent ones.
Access card or badge can be rfid tags. This is widely used not just in human, vehicular access but also in asset monitoring. contact us to know more about this.
