Card Based Access Control System A card based technology usually includes
magnetic stripe, bar code, Wiegand, 125 kHz proximity, 26 bit card-swipe, contact
smart cards, and contactless smart cards. Also available are key-fobs which are
more compact than ID cards and attach to a key ring.
It is known for their high durability as well as hassle free work performance; our
products are mostly demanded in various sectors such as residence, corporate offices
and restaurants.
Biometric Based Access Control System Access control where the identification
process is made through biometric parameters. Biometrics is a general term for the
verification of individuals using unique biological characteristics (i.e. fingerprints,
hand geometry, voice analysis, the retinal pattern in the eye). It is more secure
as compared to the conventional card based technology because of the exclusive fingerprint
for every entity. This biometric based technology eliminates the administrative
cost involved with the conventional Cards.
Network (IP) Based Access Control System
The IP based system connect to the network using TCP/IP protocol and even allows
you to add one door at a time. You can easily grow your system to hundreds of readers
over time.
This is a very easy to install door access control system since it uses your existing
Ethernet network. It can also be integrated with IP cameras used in security and
surveillance systems.
- Single & Multi-door Controllers: The door controller will be an intelligent control
unit that is used to process and manage the entry and exit transaction through each
of the access controlled doors. There are two types of door controllers- Single-door&
Multi-door Controllers. Both controllers are extensively used in small or big offices,
industries, companies, showrooms, stores and allied places. By single –door controller
you can access through single door. But in case of Multi-door Controller you can
enter or exit through more than one door.
- Readers: A device that "receives" an identification code from a card, key tag, magnetic
stripe card, bar code card, or related item. It refers to the “front end” that a
user must interact with to get an access. Readers can be keypads, card readers,
proximity readers, etc.
- Cards: it refers to an identification device assigned to an individual that identifies
that individual. Typically, it is the size of a credit card. It comes with encoded
information that, when presented to a card reader, identifies the cardholder to
an access control system, allowing that system to determine the cardholder's entrance
and exit rights. Locking devices: A manually operated or automatically controlled
switch or sensor which initiates a signal that can be processed by an access control
system to open / close the lock.
- Anti-Pass back (Anti-Tailgating): This feature protects against more than one person
using the same card or number. It defines each system card reader and card I.D.
number as IN, OUT or other. Once a card is granted access to an IN reader, it must
be presented to an OUT reader before another IN reader access is granted. Cards
will continue to have access to all authorized other readers.
- Distributed Access Control: Access control systems in which all control decisions
are made at the local controllers, independent from a host computer. Local Controller
events are uploaded to a host computer periodically for review and storage.
- Electromagnetic Lock: An electric door lock that uses an electromagnet to hold a
door closed.
- Exit Switch: A switch that is used to initiate a Request to Exit. A push button,
switch mat, proximity detector, or other device which starts a timer in the reader
interface electronics when someone is leaving through a controlled entry or exit.
The timer bypass (shunts) the door-open detector for a selected period of time.
- Fail Safe: On loss of power, access points will automatically unlock allowing free
access and signal the card access system of a device malfunction or loss of power.
- Fail-Secure: An electric lock that requires power to unlock. Also called fail-locked.
- Passive Infrared (PIR) Detector: A sensor which detects the changes in the radiating
infrared light.
- Personal Identification Number (PIN): A unique numerical code used to identify an
individual.
- Reader: A device that "receives" an identification code from a card, key tag, magnetic
stripe card, bar code card, or related item. It refers to the “front end” that a
user must interact with to get an access. Readers can be keypads, card readers,
proximity readers, etc.
- Relay: A device that is capable of opening a normally-closed circuit or closing
a normally-open circuit. When the relay is not energized, the normally-closed circuit
is complete and the normally-open circuit is open. When the relay is energized,
it switches roles, opening the normally-closed circuit and closing the normally-open
circuit. This dual nature of a relay allows for two types of applications: a device
may be attached to the normally-closed circuit so that the device is always on until
the relay energizes to turn it off, or a device may be attached to the normally-open
circuit so that the device is always off until the relay energizes to turn it on.
