STI_v3STI’s Wireless Outdoor Motion Detector Alert with 4-Channel Voice Receiver (STI-V34750) alerts a user when the sensor detects movement. When activity is detected, the sensor sends a wireless radio signal to the included indoor-channel voice receiver. The voice receiver offers 10 tones/ tunes and 53 selectable words in English or Spanish. Four tones or words can be programmed to identify which area requires assistance, such as front motion alert or pool motion. The water/weather resistant STIV34750 operates up to 1,000 feet (line of sight) between sensor and receiver.
