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