OPTEX INFINITY VXI-ST Outdoor PIR Motion Detector with Pet Immunity, 12m Range, IP55

The OPTEX VXI-ST stands apart from conventional outdoor detectors by pairing a true dual-element PIR sensor with advanced SMDA logic and double conductive shielding. This combination delivers reliable motion detection even in rain, snow, or extreme temperature swings, while the IP55-rated housing ensures long-term durability in exposed locations. With 18 detection zones split between upper and lower areas, the VXI-ST provides precise coverage and reduces false alarms caused by small animals up to 50 cm tall.

Highlights

• Outdoor IP55 rated housing protects against rain and dust
• Pet immunity up to 50 cm – ideal for households with cats and small dogs
• 18 detection zones (9 upper, 9 lower) deliver precise movement analysis
• SMDA logic and double conductive shielding ensure stable performance in harsh weather
• Selectable N.C. / N.O. alarm output for flexible integration

In daily use

Mount the VXI-ST at a height of 0.8 to 1.2 metres and it reliably covers doorways, pathways and garden perimeters. The built-in masking strips let you tailor the detection area to your property, while sensitivity adjustment allows fine‑tuning for site‑specific conditions. With a wide operating temperature range from -30°C to +60°C, this detector keeps watching through freezing winters and hot summers alike.
