Access Control

As a leading Wholesale Reseller and Installer of ZKTeco, Suprema, Honneywell, Anviz, Matrix, and Rosslare Access Control Systems in Nairobi Kenya, our range of products varies from single door access control and standalone web-hosted access control to integrated systems capable of managing thousands of doors and alarm monitoring points globally.

Access control is a solution that is absolutely required in all fields and scales as a basic element of security. From research institutes, data centers, and secure areas to factories, apartments, offices, construction sites, hospitals, schools and banks, it is widely used at places that are trying to physically protect property or information from unauthorized people. 

An access control system determines who is allowed to enter or exit, where they are allowed to exit or enter, and when they are allowed to enter or exit. 

How Informed Systems Biometric Access Control works

When a credential is presented to a reader, the reader sends the credential’s information, usually a number, to a control panel, a highly reliable processor. The control panel compares the credential’s number to an access control list, grants or denies the presented request, and sends a transaction log to a database.

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. 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.

There are three types (factors) of authenticating information or access:

  • Something the user knows, e.g. a password, pass-phrase, or PIN
  • Something the user has, such as a smart card.
  • Something the user is, such as a fingerprint, is verified by biometric measurement.

Components of Access Control Systems.

  • An access control panel (also known as a controller)
  • An access-controlled entry, such as a door, turnstile, parking gate, elevator, or other physical barrier
  • A reader installed near the entry. (In cases where the exit is also controlled, a second reader is used on the opposite side of the entry.)
  • Locking hardware, such as electric door strikes and electromagnetic locks
  • A magnetic door switch for monitoring door position
  • Request-to-exit (RTE) devices for allowing egress. When a RTE button is pushed, or the motion detector detects motion at the door, the door alarm is temporarily ignored while the door is opened. Exiting a door without having to electrically unlock the door is called mechanical free egress. This is an important safety feature. In cases where the lock must be electrically unlocked on exit, the request-to-exit device also unlocks the door.
