Title: Seems to work good
Review: This was purchased for our driveway because we live out a ways and I got tired of being "surprised" by visitors at my door with no warning. So far it works good, except maybe not as well in colder temps. It has failed to go off several times when my husband leaves for work on a cold 30 +- morning in a cold vehicle. This isn't a problem for us since I am mostly concerned with people coming in off the road, just wanted to note it. This could also be due to the distance it is mounted from the driveway (20'+). So far we have had no "false" alarms due to animals or whatever. The little buzzer sound the unit made was faily quiet. Wish it had an adjustment for loudness as well as length of time it buzzes. My husband hooked a doorbell chime to it and it works well for both of us no matter where we are in our multilevel house. Pretty good buy for the money.
