Gps Based Handcuff

The main objective of this paper is to simplify the surveillance system in the jails without any human error using GPS and GSM. In general when police authorities and law enforcement agencies need to monitor movement of some suspected person or when a suspect is prohibited from moving out of a particular geographical system, it is very difficult to keep a constant watch on the suspect. Even it is difficult to track if any prisoner among the huge number of prisoner’s escapes from the prison through underground tunnel or by hiding in some kind of opaque objects. For such situations we propose a GPS and GSM based handcuff system that will keep the track of the suspect. Now the prisoner is allowed to move within a particular geographical area. When the prisoner moves within any geographical area the system on prisoner is in range of the prison/house or facility system and it does not track him. This is done by using RF wireless system. Now as soon as prisoner goes out of the specific geographical area the system detects that the receiver is not receiving signals from the transmitter mounted in the prison. The system sends an alert message to the receiver indicating the escape of prisoner. Then the GPS tracks down the prisoner by sending the real-time location of prisoner through GSM module by sending SMS. Thus this system automates the entire process of surveillance, house arrests and for patient monitoring using a PIC family microcontroller.
