Hidden Surveillance In The Real World

Video surveillance isn't the only thing available to the public that is useful. There is audio technology that can come in handy for various different groups. When a secret surveillance task must be performed, wearable spy equipment can come in very handy. The regular eye is normally unable to view it and they are often times just as powerful as a device that is larger. Small audio surveillance equipment such as phone bugs, distant audio recorders, or cellphone-like devices are simply ideal for use in secret spy missions. In a lot of different situations video surveillance is important, but it isn't always what is needed.

Audio surveillance equipment sometimes is a must when monitoring something. For example, private investigators and police officers often use these devices to tape crucial conversations over the phone or face-to-face that is in turn used against the criminals. These devices can come in any form. For example, a button on a man's coat or even a common hat. Even simple items such as a pair of sunglasses or a lighter can be audio devices. The largest advantage to each of these listening devices is that they can be used to record valuable data without even being worn.

A good example would be someone putting down a cigarette lighter and accidently forgetting it while they walk out of a room. No one would suspect that the lighter is recording everything that happens within the room. In these cases an everyday item with one of these spy devices in it can come in extremely handy. There are even microphones that are so tiny, they are hard to see from a distance so they don't need to be hid really well.81 There are some as small as 1/8 of an inch in diameter. That means you could take a piece of gum out of your mouth and place a device beneath a table to record conversation without anyone even noticing.

An audio device could even be incorporated into a person's clothing or other personal accessories such as a purse, earrings, or even hairpieces. The most commonly known about audio surveillance device is a phone bug. The term bug has already been heard by most people from movies and television where it is used quite often. A phone bug is simply an audio device placed on or inside of a phone that is used for surveillance on conversations. It in turn sends the signal to a device that streams audio of the suspects voice. Often times phone bugs aren't even placed within a phone.

The device is usually placed around the phone and imitates some other everyday object such as a clock, a watch, etc. Another useful feature that some bugs may have is they no longer record nonstop. They can be set to only come on when there is a conversation taking place. Also you can hear only recorded voices on some and don't have to strain through background sounds. Audio surveillance can be useful when needing to hear private testimonies.
