STI-34759 STI Wireless Outdoor Motion Detector with Single Slave Receiver

The Wireless Outdoor Motion Detector Alert lets you know when the sensor detects movement in a monitored area.
The transmitter is a high grade professional motion sensor engineered with the world's best components and materials. Special Dual-Frequency infrared (DFIRT) opto-electronics provide the highest level of false alarm immunity available in a passive infrared motion sensor.
When motion is detected, the device sends a wireless radio signal to an indoor receiver, which lets you know someone has arrived. Range is 33' (10M) with a 90 degree field of view (45 degrees to each side). If the supervised transmitter is removed from the door, stolen, loses signal or battery is low, the receiver will produce a single beep once a minute. Sensor uses one CR123A battery (included), with an average life of 6-8 years in normal use. To conserve battery, when sensor is tripped it will not activate for three minutes.
Designed with pet immunity to allow the presence of pets without signaling an alarm (100 lbs./45 kg. or lighter). It includes a special micro-element lens array that produces much stronger optical signals for humans than for pets 100 lbs./45 kg. or lighter. The optical sensitivity of each STI-34752 is factory calibrated to ensure accurate discrimination between humans and pets. See install for more details.
