Wireless security system

Abstract

Today , the wireless technology has become very ordinary. The widespread of this technology makes many applications use it. One of those applications is security systems. Having a wireless security system in such way to protect small residential areas such as small department or rooms , by sensing a person come close will give you warning and enough time to react to the visitor, whether or not to allow him/her to enter. The system will be useful at different situations, for example, consider you are in a research lab that handles highly hazardous material. You don’t want anybody to enter the room, or even come close to the door. Or consider yourself doing something highly confidential in a room that you would like to know if someone is trying to get in.
