        abstract = {: It can be difficult to keep an eye on inmates under house arrest or on prison property, particularly when ongoing surveillance is necessary. Attempts to flee by covert means, like subterranean tunnels or hiding inside items, become much more challenging to identify. A GPS-based shackle system that automates tracking is suggested as a solution to this problem. This method uses GPS and GSM technology to limit a prisoner's movement inside a predetermined geographic area. The system remains dormant as long as the person stays in the designated area. On the other hand, if someone crosses the border, it identifies the breach right away, sounds an alert, and sends authorized people an SMS with the real-time GPS location so they may take prompt action.
To further improve safety, a laser-based security system is incorporated. An LDR (Light Dependent Resistor) sensor and a laser diode make up this setup. Every interruption, such a person crossing the path, stops the laser beam that is continuously falling on the LDR, causing the sensor to detect a change. After processing this modification, a controller sounds an alert by turning on a buzzer. The intrusion can also be reported to authorities by the system. When combined, these technologies offer a dependable and effective way to keep an eye on inmates and stop escape attempts, guaranteeing better security and control.},
