The QX Infinity (QXI) series consists of outdoor PIRs and dual-technology sensors that offer a 120° wide and 12m (40ft) detection area, adjustable through the provided masking strips. With a sleek and compact design, QXI sensors are well-suited for residential or commercial buildings, delivering dependable intrusion and motion detection that is tolerant to animals. This triggers the alarm panel or CCTV camera. The hard-wired model in this series is QXI-DT, featuring anti-blocking and dual-technology capabilities.

The QXI outdoor intrusion sensors offer flexibility in installation. They can be positioned at a high mount, ranging between 2.2 and 2.7m, creating a multi-level volumetric detection pattern that effectively disregards small animals. In environments where larger animals are present, the sensor can be installed at a lower height, between 0.8 and 1.2m, to establish a designated "pet alley."
