What you REALLY want is fewer breakins. That means activating something
BEFORE the breakin. Maybe put a screen door on the outside of the door
they come thru, that turns on lights and sound effects when they open
that, while your security perimeter is still unbroken.

If the walls don't give clues, have you checked above 8' and on the
roof for access potential?
My dad used a Popular Mechanics (or Pop Sci) article to design an
inductive sensor for his yard (cats breaking in) eons ago. (Everyone
hates tomcats pissing on the bushes in front of their homes, making
them smell like downtown alleys, huh?) He ran a simple wire around the
top of his fence perimeter and
Google up "inductive alarm system", Tom. Then build/buy one and use it
to rim the building, activating a 5-camera surveillance system on
alarm. One camera on each wall outside and one behind the TV to catch
_faces_. X-10 will work for a budget system with any old VCR, or send
it to the Internet for home monitoring if you're connected at work.
Or "tag" 'em with something like this for tracking. <bseg>
Nah, a 40mm projectile tag might be a bit too much for food theft,
but it would certainly get their and their friends' attention.
This might be your way to get away from ADT's bungling:
Rig up something like this
to the fridge and cameras so you catch the thieves in the act.

(with cameras/vcr/etc.) will help you catch them on film.

Do the guards have access to the inside (key)? Long ago I installed
alarm systems. More than once the minor problems were the guards
themselves. Just a thought.
Surprising that ADT isn't more helpful as your situation is not a
At my parents cottage my Dad installed a motion light and then hooked up a
large radio and big light to it. It was only ever activated twice and
nothing was missing. Try the same thing except add an audio tape that starts
when the power is activated, thief's hate voices. Activating the motion
sensor should work with a light.
I think the motion detector works or changes in the infrared levels.
So a person ( warm object ) will trigger it, but a fan will not. But
if you had a infrared emmitter placed so the fan blades modulated the
levels that the motion detector saw............ So how about a light
placed so the fan blades cast shadows on the motion detector. Easy to

No go. What you're going to need is an IR source plus a fan with
IR-reflective blades. "Your" motion detector turns on the fan and IR
source, which causes IR to be spewed around the room, and should trigger
the ADT detectors (If they aren't the "sonar" type...)

Does the ADT motion detector require movement of a "heat" signiture?
I know many of the stand alone motion detectors, (like those that work
turning on lights), will not work with just motion, but require a
"heated" surface to be moving from one zone to another monitored by the
If motion only is the need, use an occilating fan with streamer ribbons
tied to the grill, place it where it will move between two of the
spacial zones that the sensor monitors, and it should trip the sensor.
If HEAT and Motion is needed, you could use a heating pad suspended in
the air by two strings, have the separate system trigger a relay to turn
on both the heating pad and a occilating fan aimed so it passes by the
heating pad and causes it to move and swing. Maybe that will trigger
the ADT motion detector.
You asked for "any ideas?" these are free, you get what you pay for.
;-) Hope you solve your theft problem
If you own the system, install your own sensors where they will do the
most good on the premises. PIR or microwave/PIR can be seriesed with
the existing sensors. They are more than likly NC switches. Just cut
one wire, extend the loop out through the new sensors NC contacts,
splice the 12vt DC power lines and voila..new/additional sensors on
the same zones. I might even have some NOS PIRs kicking around. I
know Ive got a number of NOS photo electric beam units still in the
boxes and at least one RACAL long range microwave sensor system 1000'

why not have them add a door sensor somewhere (e.g. bathroom door) and then
use an electromagnet to close it (leaving hte door open) then you can
unpower the electromagnet when you want to trigger the alarm
Tom: We've already established that your problem is ADT themselves.
If you have told them that there are constant break-ins at the
building, and they can't figure out where they are getting in, and how
to detect them either before or after they get in, it's time to fire
them and get in another security company. While they have some real
smart people at the large security congloms, a lot of them are (to be
charitable) not the brightest bulbs in the chandelier.
Not to mention that they overcharge on the monthly rates to cover
the "Free" equipment and "Free" service, and they don't drop the rates
when the contract is fulfilled - TANSTAAFL.
Does the alarm have supervised arm/disarm? That'll pinpoint it if
it's an inside job, because the alarm company will have a record of
who armed or disarmed the system - and when. Often, the building
fire/theft insurance company will insist on supervision.
The problem is, if you have ADT put in the panel they use
proprietary crap that only they can program, or monitor. You have to
rip out the panel and start over - which is probably a good thing.
Serious suggestion: Go get one or two TV cameras or Webcams,
installed on a weekend when you're alone, and aim one of the cameras
at that refrigerator. Borrow a time-lapse VCR or use a video capture
card in a PC.
Or for a more permanent solution that (if you have a highspeed
connection at the shop and at home) you can watch from home, go down
to Costco and pick up their security system for about a grand. One
color monitor with a quad switcher and a DVR hard-drive recorder with
internet interface, and four cameras. Anything moves, and it starts
recording every frame.
Hell, you could have a raccoon living in the neighborhood that
figured out how to get inside the shop and raid the breakroom fridge.
That would explain why the PIR/MW motion sensors are never tripped,
it's under the size/mass threshhold.
If nothing else, the footage you get would certainly qualify for
entry at America's Funniest Home Videos...

I took over a contract when I purchased a house. That was the biggest
mistake I made. ADT is not the service you should have. Change when your
contract ends.... Make sure you can get out and expect to be hounded and
threatened after the contract runs out. I was!
