What is a listening device?

A listening device is often referred to as a bug. Essentially it is a device that can be used to listen to conversations or sound in its area of use and self contained. All tend to be made from solid state technology in recent years and have reduced in size over the last few years greatly. Previously bugs also used miniature radio transmitters with a small microphone for eavesdropping. However, the frequencies that these used were regulated in many countries. As such these were illegal to use unless they were authorised by the relevant authorities. For this reason, we do not recommend or sell listening devices that work on radio frequencies.

The use of listening devices (bugs), referred to as bugging, is a common technique used in surveillance, eavesdropping, espionage and investigations. Recent technology has allowed professionals and now the general public to overcome this issue by using GSM technology to dial into the device. This is referred to as the ‘roving bug’. It is possible to remotely activate the microphone in the GSM device, even when a call is not being made, to listen to conversations in the vicinity of the phone. It is just like calling up a mobile phone in the area of use.

The best and most efficient way of secretly listening, spying or recording something is a listening device (common names are a bug, spying device, etc.). Nowadays, these spying devices are at an affordable price for everyone for their personal or professional use.

Choosing the best listening device for your project isn’t just about just recording the audio as you only get one chance to capture that sound.

What is a good listening device?

These are the parameters that should be considered for a good listening device:

  1. The size of the device: As it is a spying device, obviously the size of the device should be small. The smaller the device the more discrete it will be so you can hide it in secret places, without it being spotted.
  2. The appearance of the device: In the case of spying devices, the device should not appear like an audio recorder as it will immediately raise suspicion. This is if the person is looking for such a device. A person has a reasonable expectation that you will not record them in a private place.
  3. Listening capability of the device: This is an important aspect of a listening device. The audio should be clean and clear even though the device is small and covering a large area. For example, the device should be able to record audio on every corner when the device is placed inside the room.
  4. Good Range: Finally range, recording the audio is not enough, it is equally important that you can listen in when necessary via GSM. A GSM device will allow you to call from anywhere in the world.

Now, by considering the points above, here are the best listening devices currently:
