Detect hidden camera in trial room

[parad0x]

Actually, it was posted on my timeline on Facebook and it is of great use as in some places like malls, garment-shops where dressing/changing rooms are present so that you can try the clothes you want to buy. But some of them have hidden cameras to make MMS of women and girls.  So, here is how you can detect a hidden camera is present or not.

How to Detect Hidden Camera in Trial Room?

In front of the trial room take your mobile and make sure that mobile can make calls........
Then enter into the trail room, take your mobile and make a call.....
If u can't make a call......!!!!
There is a hidden camera......
This is due to the interference of fiber optic cable during the signal transfer......

Please forward this to your friends to educate this issue to the

public......To prevent our innocent ladies from HIDDEN CAMERA...........

Can anyone verify this? I find it hard to believe that a fiber optic cable messes with a cell signal... a microwave, sure. It broadcasts micro-waves which can cause interference. But a fiber optic cable? I'm finding that one a bit hard to swallow... no offense intended parad0x, but i'd like a 2nd opinion/source on this please

I think its bullshit.
The frequency used for GSM signal is restricted for other devices.
This is another typical fairytail, dont believe anything you read on the net.
