Chamberlain Wireless Motion Alert System

I have had this for a couple weeks now, and am very pleased with it. When I first put it out, I pointed it from the garage down the driveway which is about 250 feet to the street. Well, it was picking up every vehicle that went down the road, which did not make me very happy. I adjusted to switch for distance, but it made no difference. I also had 2 trucks pull into the drive and all the way up to the house, but it did not go off to warn me. Well, I decided that it was not working properly with the trucks coming head on, but catching the vehicles going along the road, so I moved the sensor to a spot in the yard, aiming toward the driveway. Now it catches vehicles coming down the driveway, and not those going down the road. I did have to switch the distance down to the lower level, as I was picking up people entering my neighbors driveway. Now it works exactly as I wanted it to, and nobody comes down my driveway without me knowing about it. I only wish the instructions mentioned something about its placement a little better, but with a little trial and error, people should be able to make it work for their needs.

I purchased this item for my mother to use in her home. It works well inside her home to alert her when the back door has been opened. Easy set up right out of the box, no connectivity issues and seems to do the job. In regard to the volume of the base unit, it isn't that loud as some others have already reported on their reviews. We set it up in the master bedroom for peace of mind at night when my mother is alone and for her purposes it is loud enough to wake her if someone were to enter her home. If you plan on being able to hear the alert tone throughout your entire home you may want to consider a different unit. If you only need to be able to hear the alert tone in a single room this product will get it done. Overall its worth the money.
