I think I've got a problem with the motion detector that controls the
lights on the garage. It has always been 'odd'- but now it just
seems to *not* detect anything some days-- and on others seems to be
tripping when nothing is there. [though I can't rule out critters
tripping it]

It has been hanging there for 5-6 years & since day 1 it will let a
car drive right up to the garage [straight at it] and not trip until
the driver gets out of the car. It is supposedly a 180degree
sensor, but 120 would be generous, and the edges seem to wave back and
forth.

The way I have this set up, if it matters, is the sensor is mounted
above the door and operates carriage lights on either side of the
door.

The lights are switched-- but not 3-way.

So is there a *really* good detector that has a wide field of view,
and will detect objects coming straight at it up to about 100 feet
away? [minimum of 50']


I don't have any insight as to the motion detectors, but what happens when a
thief pulls in your driveway and the garage door opens?


Aside from the facts that;
1. my garage door is generally open anyway,
2. the motion detector is just to operate lights,
3.by the time the thief found anything of value in there either me, or
my neighbor would be 'talking to him'
.. . .

I would guess, that if he saw the door open, he might suspect that
someone just opened it, or someone is *trying* to get him to enter the
trap.
