This page may seem unusual for a website about communication. However, bugs and taps are devices used for surveillance of activities and communication. The word surveillance is a French word that means "to watch from above." Surveillance usually means that people, telephone calls, etc. are observed from a distance by means of electronic equipment such as bugs and taps. Bugs are hidden microphones that secretly pick up sound and conversations and send them to a transmitter or receiver. The sound is usually recorded so that the spy can hear it over again or send it to other spies or officers. Did you know that some bugs could be made from parts of hearing aids? The tiny speakers in a hearing aid can be converted into microphones to make a bug. Bugs can be very small so that they are easy to hide. Some bugs are much smaller than a pencil eraser. Taps are similar to bugs. Actually, they are a type of bug that is usually connected to a communication device like a phone or wire. They listen in on conversations. Did you know that taps can only hear a phone call but no other sounds in the room? This allows the message to be clear without interference. Bugs
and taps are best hidden in everyday objects.
These objects can include walls, lamps, phones, pocket calculators,
or on people. The type of bug
carried on a person is usually called a “wire.” You may have heard
this term on police One of the most famous bugs in history was hidden in a gift to the United States. It was a replica of the seal of the United States given by the Soviet Union. It was hung in the U.S. embassy in Moscow. It contained a vibration sensitive bug that was eventually discovered by U.S. officials.
Most
bugs are built to be used for a short time, then abandoned at the site
where they are used. They are usually abandoned because the people
planting the bugs are more likely to get caught trying to pick up the bug
than install it. Taps differ from bugs in an important way, because they may not have to be hidden on a site. Many times a phone line can be tapped miles away from the person being listened in to. Another
similar item that is not really a bug, but is often used with a bug is a
We all know that spies use bugs and taps. What other people use them in their work? a.)
Spies What
type of information do these groups gather by using bugs and taps?
Mostly, they want to know secret information that they can use in
some way. Private
investigators may use bugs and taps to spy on people suing companies or
individuals. They also may work for businesses that want to find out what
competitors are doing or planning. Not
all of these uses of bugs and taps are legal. Police need permission from
a judge before they can tap a suspect's phone or place a bug on the
suspect's property. Many times when businesses spy on each other it is illegal,
but sometimes hard to prove or prosecute. Citations Print
