Safety Technology International STI-34150 Battery Powered Wireless Driveway Monitor
Safety Technology International - STI-34150 Battery Powered Wireless Driveway Monitor. You can always be assured that the driveway monitor kit will notify you when a vehicle enters or exits your driveway. This small rugged waterproof sensor is easy to install. Plug the receiver into any standard electrical wall outlet next to your driveway. When sensor detects a vehicle, it signals the receiver to alert you by chiming and flashing. Effective range of up to 1,000 feet (line of sight) away from the sensor. The 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. Sensor offers sensitivity options of low, medium, and high. Sensor is battery operated and will require 2 C Alkaline Batteries (not included). NOTE: Maximum optimal range for vehicle detection is 12 feet; multiple sensors (purchase the STI model 34101 separately to increase range) may be required for driveways exceeding this width / range.
