Good morning Earl,

Many thanks for your explanations and tip.  However, my client is only
interested in risk mitigation so, it is unlikely that they will go for any
technologically sophisticated solution.

Pranav

BS,  if the transmitting part of the camera (antenna) is outside of the mesh
the RF will still be transmitted to wherever. I can defeat situation this in
a heartbeat. GHz is not the only frequencies (note the plural)  that
concealed cameras work on.

Ok so you need a RF broadband sniffer, much like a network sniffer only for
RF.  Another reason Ya'll ought to be Ham Radio operators (in addition to
network engineers) so you understand the fine points of RF (it is not vodoo
but rather hard mathematical science).  You are breaking new ground here as
I am not aware of an off the shelf network connected RF sniffing device.
Check Ramsey Electronics for security sniffing devices marketed as test
equipment devices.  You will need to find a programmer to interface the
device to the network grid for full time detection as these upskirt
characters are in great supply.  This will be an ongoing monitoring venture.
Check the same places that sell the pinhole cameras as they tend to also
have the RF detection equipment.  You can build an RF shielded cage but If I
was to defeat it I would drill the hole for the camera and put the antenna
outside the cage.

I have given you all the information to resolve this so here is the deal, I
know RF and I have a good programming guy if you can't engineer a product in
a reasonable time to meet your customer's needs, contact me and I will build
it for you.

Could such a mesh be installed in an already constructed structure like a
shopping maul?

No need to jam, a wire mesh placed in the walls and grounded will stop most
RF devices cold.
The mesh should be of the same type as screen door mesh (must be wire
though!) to be able to stop any 2ghz signals. The mesh would also need to be
electrically contiguous of course.

Might make it hard to drill as well, the mesh would foul any powered bits
and a hand tool would have great difficulty dealing with it as well.

One thing to do would be to build the room as clean and free from places
that cameras could be hidden etc. ie no benches etc. Make it so that any
tampering would be obvious.
Also, make the walls etc out of something that would be hard to drill a
pinhole in.

Then some of those detectors that you listed could be used-though I can't
vouch for any of them.
Maybe there's a way of jamming signals too?

Hi all,

I have been asked by a client to find a solution for detecting cameras in
dressing rooms etc. The client has trial rooms where customers can try
various garments. The concern is that  some one could plant a camera in one
of these rooms and photograph customers.

I have checked online and have found the following sources;
http://www.brickhousesecurity.com/sf-103.html
http://www.spytechs.com/bug_sweep_equip/vcd_43.htm
http://www.pimall.com/nais/countervideo.html
http://www.intpro.co.uk/pinhole.htm
http://www.intpro.co.uk/camera%20detector.htm
Are there any others? Has any one on this list tried any such solutions? I
have found an interesting reference on hiding and detecting cameras at
