| ome of my neighbors have seen prowlers around our residential area

Far more effective would be lights on PIR sensors that switch on then
any person approaches. Much more disconcerting to any prowler. YOu can
get hi-low lights (for incandescent lamps) that have a photocell and
come on dimmed overnight, switching to full brightness when someone
approaches - the best of both worlds.
