I have a tool shed at our cabin which has been broken into twice.

There is an alarm to scare off folks after they break in, and that has
been successful, but I would like to add a motion sensor flood light,
and also perhaps a fake security camera, in order to warn people off
before they break up the door.

Problem: there is a tree overhead with branches which move in the wind.
I have trimmed the tree up to about 12 feet.

Can I focus the range of the motion sensor so that the moving branches
do not set it off?

Thank you very much in advance.

I put one together for a friend some years ago.
I used a standard motion sensor flood light and
hooked a 120 volt AC Edwards fire horn to it.
The trees around it didn't seem to cause any
problems. The motion detector was a PIR (Passive
Infrared) that detects warm objects moving through
it's field of view. It did scare off several
undesirables, in fact, there was blood and torn
clothing on the barbwire fence.
