The SIP-3020WF is a low-current, wire-free PIR sensor with a 30m x 20m range, ideal for temporary or remote sites. It features an intelligent detection system that adjusts sensitivity based on ambient temperature and illuminance. With two independent detection zones (far/near), anti-masking, and vandal-resistant design, it is perfect for triggering CCTV systems and protecting long, narrow areas like fence lines, buildings, and alleyways.
