This research paper sets out to explore various border intrusion detection systems but with emphasis on wireless sensor detection method. The system described in this paper relates to the detection of human beings in particular but also offers ways of detecting non-human intruders such as objects and animals. Thus, the study aims at ascertaining the intruder crossing a specified border or perimeter under surveillance before raising an alarm. It also looks forward to provide intrusion detection mechanisms for other forms of objects that are considered to be intruding to a specified perimeter. The application is being developed for border intrusion detection problems that are mainly focused on human and any other intruder. As such, the system will focus on all forms of intrusion including objects. There is also need for an intrusion detection system to ascertain the identity of the intruder.
