Different Types of Access Control System Available in India

Technology plays an important role to enhance safety and security of your premises. It also helps to maintain the record or attendance of entry and exit of people from your premises. The methods to identify and provide authentication to a person depends upon the design and technology used behind Access Control System. Such systems are of several types such as:

  • Vein Pattern
  • Finger Prints
  • Hand Geometry
  • DNA
  • Voice Pattern
  • Iris Pattern
  • Signature Dynamics
  • Face Detection

The article will cover the types and functioning of various Access Control Systems. These systems are consisting of biometric sensors which convert the biometric treat of a person into an electrical system that’s why these are also known as biometric systems. Each access control system has a built-in scanner or camera or microphone to sense iris and vein pattern, face and voice respectively to sense human traits. Some popular access control systems are:

Finger Print Recognition: It scans the fingerprint image of a person and records the features like arches, whorls, loops with outlines of edges, minutiae, and furrows. The Fingerprint Access Control System matches a fingerprint in three ways like minutiae, ridge and correlation.

Face Recognition: It is used to identify a person by comparing and analyzing patterns formed in a digital image. The latest facial recognition system can recognize 80 nodal points on a men face. Nodal points are endpoints which are used to measure variables on person’s face including the length and width of a nose, cheekbone shape and depth of eye socket.

Iris Recognition: It is a type of Home Automation System used to identify a person by identifying its eye retina. It is based on a single pattern using a ring-shaped surrounding the pupil of an eye. The iris consists of colours such as blue, brown, grey and green with different patterns that can be noticeable upon closer inception.

Voice Recognition System: The system produces various speech patterns by adding behavioural and physiological factors that can be captured by processing speech technology. Such a system uses several properties for speech recognition such as nasal tone, fundamental frequency, inflexion, and cadence. Voice recognition can be separated into different categories depends upon the kind of authentication domain like fixed text method, the text dependent method, the text independent method and conversational method.

Signature Recognition: It is used to identify a person by sensing its signing activity such as pressure applied, stroke order and speed. A few Digital Door Locks works in two different ways like static and dynamic. Static mode uses a signature on paper to scan the pattern and a dynamic mode uses a digitized table for signing. Another system uses stylus-operated PDAs to capture the signature style. Some systems can attach to smartphones for identification. A person will sign on its mobile screen using a pen or a finger.

The Door Access Control System is used in numerous companies providing both security and attendance. Now you do not require keeping an attendance record of employees. Such Security Access Control System In India enables you to check the attendance of employees besides preventing unauthorized access.
