The phone tap is one of the more common types of surveillance
activities. The military, government agencies, and police use
phone taps to listen to conversations. Additionally, there are
private investigators and amateur spies who each use some sort
of phone tap to obtain information. It is even possible for
regular people to participate in phone tapping, if they have the
right equipment. This can be helpful in amassing evidence in
divorce cases that my include allegations of infidelity or in
instances of feeling threatened by someone else.
In order to set up an effective phone tap, however, it is
important to know what types of taps there are, as well as what
each kind of phone tap does. You should carefully consider your
situation and your budget, and then choose the type of phone
surveillance that works best for you.
Soft. This type of phone tap is becoming more and more prevalent
as technology advances. This is because a soft tap uses special
listening software. The idea is to tap into the phone system of
a company or a home. Even tapping into the software at the phone
company (even many land lines are now serviced at the phone
company by digital lines) can be done. By modifying the software
that acts as the “switchboard and eavesdropper can obtain access
to conversations. It is fairly easy to find this sort of phone
tap, as long as you have unrestricted access to the system that
is affected by the tap.
Hard. The hard phone tap is one where there is actual physical
contact with a wire. For instance, a secondary wire is attached
to a PBX cable or to a transfer box containing the desired line.
A third location receives the signal via a bridge. There is no
way for the parties on the line to detect any interference, and
it is very difficult to use a bug sweeper to detect a hard phone
Transmit. A transmit phone tap is one that sends information
using airwaves. This means that there is no hooking into a line
and there is no need to hack into a software system. However, a
transmitter gives off a great deal of RF energy. Nearly any
person can use a bug sweeper to detect this type of phone tap.
