Uses for Private Investigator Surveillance Equipment

High-powered zoom lenses help PIs photographs subjects from afar.

People pay private investigators (PIs) to track other people. PIs are
licensed professionals who help their clients learn a target's
whereabouts and information about his activities, transactions,
conversations and documents. Spying and surveillance of this kind can be
occasioned by divorces, business problems, lawsuits and deadbeat parents.
Often people use PIs to find out whether their significant other is
cheating. To track their targets, gather information and document events,
PIs use a number of surveillance tools -- some high-tech.

Global Positioning Systems


* Part of surveillance is keeping track of the target. PIs use
global positioning system devices to keep tabs on where their
targets go. Many devices are made to stick discreetly under cars,
and some are small enough to slip into a purse, briefcase or
computer bag. Investigators can then monitor the subject's movements
from a digital screen in their office or car.





Camera Lenses


* High-powered zoom and telephoto lenses help investigators watch
events from a distance. They have the double advantage of being able
to capture images the clients may want. Powerful lenses can be very
large and noticeable, requiring PIs to be careful about where they
position themselves to avoid drawing the attention of their subjects.





Micro Cameras


* Advances in technology have led to very tiny cameras, sometimes
as small as a pinhole. PIs can place these strategically in people's
clothing, particularly hats and coats where they are less likely to
attract attention. In some cases, the investigator may wire himself
with cameras; in other cases it may be a client. Occasionally PIs
covertly attach cameras to their subjects' belongings, desk or --
when possible -- articles of clothing.





Listening Devices


* Investigators have access to numerous types of small but
powerful listening devices. Some are designed for PIs to listen
through doors and walls. Others -- commonly known as bugs -- are
very tiny microphones, both wired and wireless, that can be placed
in rooms, in belongings and on people. These transmit signals to
digital recording devices. Simpler systems require recording devices
to be within short range. More sophisticated technology allows for
long-range transmission to remote locations, which allows
investigators to be off-premises and completely out of sight.
