Motion detector PCBs are equipped with high-sensitivity infrared, microwave or dual-sensing sensor modules, which can accurately capture subtle motion changes and heat radiation fluctuations within the monitoring range. Through precise signal screening and data logic judgment, they effectively filter invalid interference signals and quickly trigger linkage actions such as alarm sounding, camera recording and automatic light activation. Featuring small size, low power consumption and fast response speed, they are widely used in indoor anti-intrusion and outdoor regional security monitoring systems.
