<br/><br/> In daily life, the potential of readily available energy sources is often overlooked. Simple<br/>actions like walking, creating vibrations, or even the natural presence of sunlight hold<br/>immense untapped potential for generating electricity. While these sources may seem<br/>ordinary, they can be innovatively harnessed to sustainably and reliably meet energy<br/>demands and power critical systems, such as security infrastructure. This paper presents an<br/>anti-theft security system powered by a hybrid energy solution that combines solar panels<br/>and energy harvesting technology. The system utilizes solar energy during daylight hours,<br/>while mechanical energy from vibrations, such as human activity or motion, is captured to<br/>supplement the power supply. Each platform incorporates 20 piezoelectric PZT (lead<br/>zirconate titanate) transducers, which not only contribute additional energy but also serve<br/>as vibration sensors. The prototype was installed on the third floor of the PPET Building<br/>and tested over a seven-day period. Results demonstrated that the hybrid system efficiently<br/>powered the 50W security system, with the battery ensuring continuous operation. The<br/>hybrid power system, combining a solar panel generating 20W and a piezoelectric<br/>generator delivering 3.7V, was supported by a 12V, 20Ah battery. Three trials were<br/>conducted per category: hybrid power, CCTV functionality, piezoelectric sensor, and<br/>messaging and alarm performance. The sensors detected vibrations accurately across all<br/>trials, activating alarms within 2 seconds and sending alerts within 3 seconds. This hybrid<br/>system is especially suitable for critical security applications in urban areas, where high<br/>foot traffic and sunlight availability can maximize the energy generated by both solar<br/>panels and piezoelectric generators.<br/><br/>Keywords: anti-theft system, piezoelectric generators, solar panels, hybrid energy,<br/>renewable energy
