The equipment available for surveillance has come on in leaps and bounds over the last 5 years. It used to be that you could listen into conversations using either airband or UHF transmitters which sent the audio out of the room where the bug was hidden and to your receiver which in the case of airband transmitters was only a matter of yards and with the higher power UHF possible a few hundred metres if you were lucky.
However all that has changed with the advancements in mobile phone technology and our desire to have everything pocket size or indeed smaller. You can now install a tiny matchbox size listening device into a room and listen into conversations around the device from literally anywhere in the world.
You can buy a GSM Bug for as little as £149.00 at www.active-spy-shop.co.uk and they can be installed into clocks, plugs, even picture frames.
The devices work with a Sim card and you effectively dial into the sim and the device answers as would a mobile telephone. The high grade microphone then activates allowing you to clearly hear wht is being said in the room.
With a standy battery life of over 7 days this amke the GSM Bug the new kid on the block and is becoming very popular as more and more it gets discovered by those that need to spy.
