A fingerprint scanner is an intelligent device which takes place of a human analyst by collecting a Fingerprint sample and comparing it to other samples on record. It has optical scanners and detectors which scans and record the unique pattern of Fingerprint ridges on the skin. A fingerprint scanner system has two basic objectives: (1)…. Read more >>

What is Barcode: A barcode is an optical machine-readable representation of data. Barcodes represent data by varying the widths and spacing of parallel lines, and may be referred to as linear or 1 dimensional. Barcodes originally were scanned by special–optical scanners called barcode readers, scanners and interpretive software are available on devices including desktop printers…. Read more >>

Limit switches are Mechanical Switch which is used to make or break an electrical circuit during certain positions of a repetitive movement. The Basic purpose of a limit switch is to switch discrete outputs on or off based on the position of a rotating shaft. The point at which an output switches on or off,… Read more >>

Infrared Light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers. They are longer than that of visible light but shorter than that of terahertz radiation microwaves. IR is used in the security system as because Human at normal body temperature radiate chiefly at wavelength around 12 micrometer s. An infrared camera is… Read more >>

The incorporation of computer intelligence and network connectivity into devices and systems—the basic convergence influence—allows systems to be of greater and greater real-time benefit to the systems users. The widespread deployment of personal computers and networks has resolved, for all practical purposes, the connectivity barrier. Driven by relentless customer demand for improved systems, a number… Read more >>

WHAT IS CCD?? A charge coupled device (CCD) camera is an apparatus which is designed to convert optical brightness into electrical amplitude signals using a plurality of CCDs, and then reproduce the image of a subject using the electric signals without time restriction. Charge coupled devices or CCDs are arrays of semiconductor gates formed on… Read more >>
