It is no easy task to go through a house, hotel room, or vehicle in the quest for hidden eavesdropping devices. Obviously, these devices are well designed and easy to camouflage, making their search all the more difficult. However, every scientific innovation has a counter innovation. The same applies to listening devices too. This article has some useful tips for successfully locating such devices.

Searching for Discreet Listening Devices

There are so many people who may be interested in keeping track of your private conversations. Be it a suspicious spouse, a competitive colleague, a business rival or just about any person if you happen to be an influential personality. In any of these cases, if you have even the slightest suspicion of hidden eavesdropping devices in your private space, you can use some of the ideas and instruments mentioned below to feel confident about maintaining your privacy.

Popping or Static Sound on Phones
One common way to detect a listening device is by wearing a pair of headphones to cut off all sounds except those from the phone. Now concentrate on the sounds heard over the phone. Do you hear a faint static sound just like the one heard on radios, or an occasional popping noise? If your answer is yes, then it might be the sound of a radio transmitter, proof that you're being discreetly eavesdropped upon.

Checking Phone or Cell Phone Instruments
There are some radio transmitters that are so tiny that they can be easily slipped into a telephone instrument or a personal cell phone while you're not around. These radio transmitters are really small, about the size of a small electronic chip. Make sure you understand the design of mini-transmitters as well as the contents of your phone's instrument. You can now open the instrument and scan the insides for any peculiar radio transmitter like object.

Infrared Camera
You may also use a new-age infrared camera that helps detect electronic bugs by scanning a location for heat waste and thermal conductivity. Cooling the room down first and then scanning it for any of the above signals may help confirm the presence of an electronic listening bug all the more.

Magnetic Fields
You may choose to buy a state-of-the-art magnetic field detection device too. All you need to do is turn it on and move it around the suspected premises. The disadvantage of this piece of equipment is that it is likely to misguide you by picking up signals from your household electronic appliances around you as well.

Some Extra Tips
  • At home or at work you may receive intimation or an anonymous tip about the possible chances of your conversations being heard. Do not panic. There might actually be a few hidden electronic bugs or cameras around you, planted to catch some of your candid private conversations. It is best to personally clean your room and work cabin while no one is around. You might actually end up locating some discreetly placed devices, e.g. behind a picture frame, inside a flower vase, etc.
  • To increase privacy of conversations in your workplace cabin, you may opt for installing some powerful jammers or state-of-the-art gadget identification system at the entry point of your cabin. This will help you disable hidden devices as well as control plantation of new hidden devices.
  • Make sure you're alert while talking to others during your normal conversations. If you accidentally get to hear someone speak about some discreet matters that were not revealed by you to anyone, it is quite likely that you have been discreetly heard.
Eavesdropping and hiding listening devices to invade someone's privacy is an offense. If you find someone is doing this to you, it is your right to get some legal help. In the meantime, you might need to take initiative and use the above tips to make your life leak-proof.
