Ignores Animals Up to 100 Pounds

Designed to reduce false alarms, the STI Wireless Outdoor Motion Detector senses motion up to 33 feet away, while ignoring animals up to 100 pounds. The weatherproof detector also features Dual-Frequency infrared (DFIRT) opto-electronics to further minimize the chance of false activations. When a true alarm is activated, the detector signals your STI wireless receiver (sold separately) to alert you.

  • Senses motion up to 33 feet away within 90 degrees
  • Ignores pets up to 100 pounds (45 kg)
  • Supervised for low battery and signal reception
  • Compatible with any STI Wireless Alert Series Receiver

The battery-powered motion detector installs outdoors either on a flat wall or in a 45-degree corner with the included screws. If its tamper cover is opened after installation, a tamper signal will be sent to the receiver. Additionally, if the unit is removed from the wall, loses signal, or has low battery, the receiver produces a single beep once a minute.
