About Safety Technology International, Inc. STI-34151

Safety Technology International, Inc. - STI 34151 Sensor for battery wireless driveway - transmitter. If you have a long driveway and need more coverage. This battery-powered STI Wireless Driveway Monitor Sensor extends the detection range of your STI monitor system. Multiple sensors are ideal for long or wide driveways that reach beyond a single sensor's 12-foot detection range. Simply add sensors where your existing sensor can't reach. The small, rugged, waterproof sensor easily mounts next to your driveway on the included stake. When sensor detects a vehicle, it signals the receiver (STI-32530 sold separately) to alert you by chiming and flashing. Driveway sensor uses a patented magnetometer sensor system. Movement of any large metallic (iron or steel) object with a magnetic field causes the sensor to transmit to the receiver. People, animals and shadows will not trigger the driveway sensor. Sensor operates up to 1000 feet (line of sight) away from the receiver in your home. For best performance place sensor within 500 feet of receiver. Contents: battery powered sensor, mounting kit, wall mount, screws. Note: requires the STI-32530 wireless chime receiver (sold separately). Requires two C alkaline batteries (not included).
