The security detection system is exactly a method by which something is secure through a system of interworking components and devices. The rate of abduction and theft in the world is growing by the day; this imbibes fears that become a menace to the economy, peace, and development of any country nowadays. It is vital to develop viable technologies that will secure the properties and lives of humans as countermeasures to tackle this kind of problem. With the aid of the latest development in technology nowadays, it is possible to secure the properties and people’s lives using a security detection system that will monitor, guide, and protect the environments that need to be secure against burglars and abductors. A security detection system was developed to watch over the four (4) square walls north wall, south wall, east wall, and west wall. Each of these walls is equipped with a sensor designed using a light-dependent resistor (LDR) and light-emitting diode (LED) whenever anything crossed the walls he or she blocked the light-dependent resistor (LDR) from receiving light from a light-emitting diode (LED) that makes the light-dependent resistor (LDR) to output 0 volts to peripheral interface controller (PIC), whenever the peripheral interface controller (PIC) detects 0 volts it sends a signal to liquid crystal display (LCD) to display that, that particular wall has been crossed, and the system will immediately rotate the dc motor that carries the closed-circuit television (CCTV) camera to stop at the crossed wall to capture a real-time video and send to the buzzer, the function of the buzzer is to sound an alarm informing an intrusion has occurred in that specific wall. If the peripheral interface controller (PIC) detects 5 volts from the entire walls light-dependent resistor (LDR) it means that none of the walls are being crossed, if all wall light-dependent resistor (LDR) output 5 volts the peripheral interface controller (PIC) will display on the liquid crystal display (LCD) “All walls OK”.
