We have one of the Chamberlain alarms and they do work well. We have a couple of receivers, and each has its own alert. Front and rear of the house are discreetly covered.

I change the batteries twice a year, sometimes three, if its a real cold winter.

Even with the alarms, the dogs always seem to know someone is here before they go off. They dont need batteries.
