I recently bought this to replace a much more expensive motion alert for our drive through. The sensor was easy to install and getting to the batteries just took a small Phillips head screwdriver. The alert part plugs in only taking up one outlet. There is no setup needed! Our sensor is outside about 15 feet from the indoor unit. It alerts consistently to cars without many false alarms. The best part of this unit is that the bell sound is loud enough to hear but is not super long and annoying like many of these units can be. It really is hard to do any better for the value, ease of use, and functionality of this alert system!
