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.

With some models, yes. You need to check the specs re range and angle.
I used one like this

and was able to "aim" it so it only came on for motion in a small area.

*You can aim the sensor according to your needs and some of the better
models have a sensitivity adjustment. It is also possible to mount a motion
sensor remotely from the lights being controlled.

X10 has wireless sensors and motion sensors that can be made to turn
on multiple lights. Have wireless sensors low under branches or on the
shed turning on how ever many lights you want. I use them, as an
example one sensor in my garage turns on lights in garage, outside
garage, on house and in house , all wirelessly. Set it up so a theif
gets hit with alot of light from many areas. X10 wireless sensors are
about half the size of a pack of cigarettes, so they are not seen
easily.

How about a bear trap inside?

A poster mentioned X10. They make some pretty good stuff on the cheap.
Well worth looking into. X10.com

X 10, Leviton, Smart Home, might be compatible, even 3 button car
remotes and GMs can control X10, so you can turn on the coffee maker
from your car if you want.

I've set the sensor for my detached shop to turn on 2 floodlights and to
sound a 120 db warble siren. The system can be controlled from the house or
shop.

Most of these sensors sense changes in heat, not real motion. Branches moving at
night should not affect them significantly.

Many years ago when I regularly traveled to a rural part of South Carolina,
I used to stop at the convenience store at the interstate exit that had a
sign on the door that said:

Fair Warning to burglars. Man with shotgun sleeps in store three nights a
week.

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.

Tree limbs CAN set off infrared sensors. The limbs may have a
different IR signature than other objects in the background, and
motion can set off the sensors, depending on how sensitive it is.

If you can't aim the sensor away, you can use electricians tape in the
color of your choice to blind portions of the sensor as needed.

You can mask parts of the lens with electrical tape. I don't think trees
would cause much of a problem though. Also keep in mind that motion sensors
are most sensitive to motion -across- their field of view. If you walk
directly towards it, it will have a hard time detecting any change in heat,
especially if it's in the summer.

I believe that -passive- infrared detectors (most light switches are
passive) are only triggered by objects emitting heat, such as a person's
body. Active IR detectors emit IR light themselves and might be
triggered by other moving objects.

But in your case, I don't think that the branches will trigger it. But
maybe they might mask movements beneath them... Difficult to tell
without seeing the situation, still there should be line of sight
between the sensor and the person, so no leaves in between.

X-10 is good because you can put the motion detectors near ground
level if you want, although they're not 100% reliable.

Which is why you should probably not use them to power a coffee-
maker-- on rare occasions things turn on or off by themselves. Not a
big issue with lights but with things that produce heat it's a
different story.
