Negative Positive
Title: Alert System review
Review: Device does not perform as advertised. I purchased system primarly for a drive way alarm. The sensor does not pick up a car or truck if it is traveling faster than a person walks. It does pickup a person or animal walking. The inside alarm device is not very loud. The range of the device as advertised (900 feet) is also questionable. I could not get it to work over 100 feet even with new batteries.
Is the review positive or negative?
