Overview of the STI Wireless Alert Series with Voice Receiver — driveway monitors, mailbox alerts, garage sentry, and motion detectors, all paired with a 4-channel voice receiver.
The STI Wireless Alert Series with Voice Receiver (STI-V34xxx) pairs a wireless sensor/transmitter with a 4-Channel Voice Receiver that speaks programmable voice alerts when a monitored site is tripped.
The Wireless Alert Series wirelessly monitors up to 4 different STI devices from a single, convenient location. When the included 4-Channel Voice Receiver detects a tripped site, it sounds a programmable voice message identifying which transmitter activated. The receiver offers ten tones/tunes and 53 selectable words (English or Spanish), is supervised for low battery and signal reception, and operates up to 1,000 ft. line-of-sight. Typical uses: open/closed garage door, mail delivery, a car in the driveway, a fence gate, a medicine cabinet, or indoor/outdoor motion.
Detects a vehicle entering or leaving the driveway; movement of any large metallic object near the sensor triggers the receiver.
Sounds a voice message when the mailbox door opens.
Sounds a voice message when the garage door opens, and reports open/closed status.
Alerts when a monitored site is tripped — medicine cabinet, fence gate, window, shed, etc.
Water/weather-resistant button, up to 500 ft. line-of-sight range.
Sends a signal on detected motion; will not re-trigger for three minutes after tripping, to conserve battery.
