Surveillance and Security for Correctional Facilities

Prisoners are segregated in different wards. But it is the tendencies of a few bad elements to leave the barracks on the pretext of availing medical services, canteen services and telephone services etc., and going to some other barracks to receive or distribute prohibited articles. To overcome this situation, a system is proposed for the surveillance of the prisoners, using biometric sensors for monitoring purpose. This project overcomes the limitations of the existing systems of correctional facilities. In this proposed method the finger prints of the prisoners are taken as input and the other parameters that apply are the source and destination along with the time difference. Thus, the proposed system will make prisons more secure. This work provides more secure and efficient way to eliminate the wrong traversals and to inform the officials about it when this happens. The biometric sensor along with LED display, the alarm, RF receiver, RF transmitter is integrated with the PIC microcontroller. The fingerprint module takes the input and identifies the prisoner and then displays the details in the LED screen. Source controller RF and the destination RF interact, as soon as the prisoner checks in, the timer starts to function and counts until prisoner reaches. If the prisoner does not reach before the average time taken, then the alarm goes on and the official can know along with the prisoner ID on the screen. Thus the proposed system gives a better monitoring and control over the prisoners.
