We have seen lots of Bond movies where you see him spying on the enemy to gather some intelligent information on his whereabouts. The question is how is it possible to hear someone without being present there. The answer to this is a device called a bug transmitter.

There are different kinds of bug transmitters being developed these days. One is a listening bug which receives frequency around a 20 meter radius which enables people to listen to any conversation that is happening at the other end where you cannot be present.

If used in proper and effective manner, you can really use it for the good of the country. That is why lot of intelligence companies are using such devices to catch bad guys and store documents which will help as an alibi against their wrong doings.

Other kind of bug transmitters are in the form of hidden cameras where in you can capture the live feed of the happenings of where you install the bug transmitter.

With a high sensitive GSM surveillance bug transmitter, you are given a sim card and device where you insert that card. Then you can install the bug wherever you want and then using your phone you can dial that sim number and you will able to track the location of that bug. Also you will be able to hear the sounds close to the bug.

This type of transmitter is useful when you are following someone. In case you are following his car so you can out in the back of his car or the best option is to slide it into his pocket.

With the power that these devices possess, they can be used in the form that instead of protecting your country it will be used against it. So with technology also comes the responsibility of using it in a manner where in it is used in a matter of self defense only.
