Question ID: 19023
Is there a way to interrupt or somehow interfere with a miniature
fiber optic video transmission?  I have recently discovered that
someone has bugged my home with many of these.  As of yet I am
unprepared to bring the police into the matter and would like to find
a way to inexpensively do this --- such as simple home remedies --
does foil work??

Foil will work as this is called a simple gaussian surface, but you
must cover the ENTIRE transmitting device creating a completely
touching gapless surface. By Gauss' Law (I just took Physics III and
it's all about electromagnetic waves) any electric field cannot pass
through a closed gaussian surface, what's outside stays outside, and
what's inside remains trapped inside. This is the same principle of
why cell phones do not work in elevators (well metal ones at least,
glass doesn't count) and the reason why radios don't work in tunnels
(unless there are repeaters installed of course). Another less
practical solution and it might not work depending on the frequency of
the transmitted radio is to turn on and keep on as many electric
motors (read: vacuum cleaners) and place them in close proximity to
the devices, that might generate enough noise to knock out any viable
transmission. Regardless of how you choose to proceed, I would HIGHLY
recommend contacting the police in this situation though, as an
invasion of privacy isn't your only concern. The people who have done
this to you have access to your house, and your safety is compromised.
Should you require security services but do not wish to alert the
police for some other reason, contact local bodyguard and/or personal
security consulting firms in your area. Hope this helps, clarify your
question if you need more info, or rate my ansewr if you feel it's
satisfactory as is. Thank you very much!

Another approach if you know where all the transmitters are would be
to remove the batteries.  Or if they're adjustable you could set them
all for the same frequency so they interfere with each other.

refering to your question which includes "fiber optic wireless video
miniature cameras" just a point but doesn't the phrase "fiber optic"
mean these cameras are wired by a "Fiber Optic" Cable. or is that just
me.

Now if it was me personally. i would remove the cameras, which
incidentally would be worth a reasonable amount of money and sell
them, which would proclude that chance of this happening again.

if this does happen again, then sell them again. and the Person(s)
responsible would soon give up.

also you do not need to stop a camera transmitting, you only need to
block its sight with the use of black spraypaint etc...

hope this give's some usefull insight along a different train of
thought :)

Cheers
