Signal Tech is a specialist in electronic access control systems, offering installation services across a wide range of products and technologies designed to restrict physical access to selected areas and resources while maximizing security. To gain access, individuals must provide one of three key elements: something they have, something they know, or who they are. These principles underpin the use of access cards, keypad readers, and biometric scanners, respectively.

Manual locking mechanisms have been employed for centuries as humans strive to combat security challenges and theft. A significant drawback of traditional manual locks is the risk of losing keys, which can lead to unauthorized access if they fall into the wrong hands. In contrast, digital access control systems utilize credentials in the form of access cards or biometrics, securely stored within the building's system. Each time a user enters the premises, their credentials are verified to grant access.

If an access card is lost, its credentials can be quickly revoked from the system, and a new card can be issued. Biometric systems, which utilize body parts such as fingerprints and facial recognition through face and iris scanners, offer the additional advantage of being impossible to lose or duplicate. These systems can also be used in combination with access cards to provide multifactor authentication.

An access control system consists of keypads, card readers, fingerprints, facial recognition, and iris scanners to detect and authenticate individuals, granting them access. At the heart of the system is a controller unit that can be linked to management software via a network for user events storange,area configurations and policy implementation.
