Tamper-Resistant Motion Sensor Triggers Custom Alerts

Receive custom voice alerts when motion is detected indoors with the STI Wireless Indoor Motion Detector Alert Kit with Voice Receiver. The motion detector senses movement up to 44 feet away within 90 degrees (45 degrees to each side). When the sensor detects motion, it signals the receiver to alert you with voice messages.

  • Detects motion up to 44 feet away within 90 degrees
  • Voice receiver sounds programmable tunes or voice alerts
  • Wireless range up to 1,000 feet
  • Supervised for low battery and signal reception
  • Receiver supports up to four sensors

The battery-powered motion detector installs indoors either on a flat wall or in a 45-degree corner with the included screws. If the detector's 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.

When the Voice Receiver is activated by the motion detector, it sounds your choice of 10 tone/tunes and 53 words (available in English or Spanish). With four channels, the receiver supports up to four sensors (additional sensors sold separately). Each connected sensor can trigger a different selectable alert.

How to Create Custom Voice Alerts

The receiver's library of selectable words can be programmed in sets of up to four to create a custom message (i.e. "Emergency + Exit + Side + Door", or "Front + Door", or "Pool + Gate", etc.). There are also four LED zone indicators (latching or momentary) to further help you identify which sensor was triggered.

The receiver plugs into any indoor power outlet with the included adapter, up to 1,000 feet away from your wireless sensors. It can be mounted on a wall, or simply placed on a tabletop. Programming is simple with voice prompts.
