INFALLIBLE SECURITY SYSTEM?

[Graham Cooper]

My ex worked as security manager of a big department chain, her beeper
would always be going off in the middle of the night, assigning guards
to smashed doors, getting safe experts from interstate to follow
diagrams to cut holes in explosive safes..

She was quite interesting and told me a lot of the tricks the crims
use!

Like a battery powered alarm in a stairwell can be defeated on long
weekends!

How to sit at tables and cover both exits, how 2 tail somebody with 2
cars and a CB, how early PIR detectors with a flashing LED you could
learn how to walk directly towards them without crossing the beams..

Anyway I bought a SOLAR POWERED PIR ALARM and screwed it into a tree
trunk near my car. Here's a simple method to cover an entrance area
without being tampered with.

2 PIRS that cover each other! Try to smash one and the other picks it
up!

All you need on top of that is a light signal from each PIR so 1 PIR
detector also detects when the other PIR has stopped working.

i.e you won't be quick enough to shoot BOTH of them with a gun at the
same time!

To be guaranteed secure, the "LIGHT-ON-DETECTOR" lights could have a
narrower beam than the PIR beams, so you couldn't learn the ON-SIGNAL
with a Light Sensor. Beware people borrowing your car keys and using
a Learning Remote on them!
