Looks at the regulation and access control procedures of persons entering certain areas.
“Access control is the regulation of persons entering a certain area. Access control can stop or at least slow down unauthorized entry and therefore crime. A good access control system can eliminate the potential for internal and external theft, a huge problem in American business. The security of a building and everything inside of it is dependent on controlling those who enter the building. The most basic form of access control, keys, has been around in one form or another since long before the supposed birth of Christ. Other electronic access control systems have been around for approximately twenty-five years. In the past, identification of personnel was thought to be a strictly human function. Security guards and bank tellers were responsible for identifying all the people they came into contact with. The cost of using a person to recognize and identify other people is high and isn’t economically possible in all situations. It’s been estimated that over a one year period it takes five security guards to cover one entrance, twenty four hours a day, allowing for a five day week and the normal vacation and lost time. Human guards are not perfect. They get tired and can make mistakes. In some cases they even collaborate with an intruder. A system is needed that can automatically identify authorized persons, or assist the guards that are responsible for the identification. “
