A driveway detector / chime system based on a buried probe that detects moving metal eliminates many false alarms and is good at detecting vehicles, but of course it won't detect people unless they're packing an awful lot of steel.smoothoperator wrote:I agree in the example you gave where breaking the beam sets off an alarm that notifies the cops. However, something that rings a doorbell chime inside the house and/or triggers a driveway light is a different story. For me, the occasional false alarms aren't a big deal. Just from the convenience factor, it's nice to know the UPS driver is coming, and having my driveway light up when I come home after dark.papajohn1964 wrote:I wouldn't put a beam anywhere outside. They can be set off by dogs, cats, birds, grass being blown in the wind etc... You would have to run wiring out to it for power anyways so put a magnetic door contact on it instead.
I like both visible and hidden cameras, and for different reasons.

Re: pros & cons of obvious security vs. hidden
Unfortunately, life isn't that simple.Moby wrote:Most criminals are cowards and the thought of being photographed or filmed is very powerful. There are easier targets.
I own a small business in a commercail metal bulding of 5 units. I have video cameras and if you look throught my glass door you see yourself on camera.
Both units on either side of me have been broken into, not mine. A game camera can be placed high enough so it cannot be reached without a ladder.
A flash indicating obvious survailance will deture all but the most determined criminal. I say this from direct expeirience. Not theory.
VIDEO WORKS! Also put up ADT type alarm stickers. And make sure you actually have an alarm. It just says GO AWAY to criminals.
(and lock your back gate)
Research on cameras that simply record (as opposed to those constantly monitored by police) is inconclusive regarding a deterrent effect.
While an individual criminal may be camera shy (which commonly happens when he is well known at the target location), most are not.
Keep in mind that every video you see on the evening news showing a convenience store, bank, jewelry store, or pawn shop robbery was filmed by obvious, conspicuously placed surveillance cameras.
