Visitor Management System, an Overview

Thursday, September 1st, 2011

Visitor Management System Gone are the days of primitive visitor management! Electronic devices for the process are the need of the day. Areas with a large number of visitors adopt the services of this system to keep a track of the people checking in and out of the building. Schools use the system to prevent… 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 >>

What is Fiber Optics: Data is of no use if the storage and transmission is not proper, transmission of Data is the main concern behind every Security System. An administrator can access and control his/her system from a long distance across seas. The long distance data transmission requires a special channel. One of the long… Read more >>

Serial transmission technology is increasingly used for the transmission of digital data. A large number of up-to-date communications networks apply serial transmission. The numerous applications include computer networks for office communications, Access Control, building and manufacturing automation, Internet etc. Serial data transmission implies that one bit is sent after another (bit-serial) on a single transmission… Read more >>

Over the years, the use of thermal cameras has expanded. Once widely used only for surveillance and security, the current technology has made these cameras serve many other useful purposes. The infra red technology which detects heat energy can detect the minute temperature changes and this is generated as an image on a screen. The… 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 >>

­Switches are the most fundamental part of network. Switches allow different nodes (a network connection point or a computer), i.e- a switch is an intermediate station which interconnects the communication links and subnetworks to enable transmission of data between the end stations. Switching involves transferring information, such as digital data packets or frames, among entities… 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 IMAGE SENSOR: An image sensor is a semiconductor device that converts an optical image into electrical signals. A CMOS image sensor is a device that converts an optical image into electrical signals using MOS (metal oxide semiconductor) transistors. The CMOS image sensor sequentially detects electrical signals of each unit pixel in a switching… Read more >>
