Review: STI-34100 Solar Wireless Driveway Alarm System

sti-34100Summary: The STI-34100 wireless driveway has a decent solar powered sensor that detects cars only. However, I recommend the Dakota 2500 because it has a higher quality motion sensor (accurate and no false alarms).

The packages include 1 chime receiver, 1 receiver antenna, 1 solar powered motion sensor, mounting hardware, AC adapter and 2 AA rechargeable batteries.

How It Works

Whenever the solar powered magnetometer sensor will detect a vehicle, it will send a signal to the receiver. You will then be notified be notified by a chime and a flashing LED.

Installation Tips

  • The sensor should be at least 25 feet away from roads in order to avoid false alarms
  • Mount the sensor in an area with partial or full sunlight
  • Do not install the sensor more than 3 feet away from the driveway

Bottom Line

The STI-34100 wireless driveway alarm features a solar powered magnetometer sensor. In comparison to other alarms, the sensor does a decent job detecting cars. However, you will get false alarms every now and then. I recommend the Dakota 2500, which has a state-of-the-art motion sensor.
