Operating Principle
 The
SpyFinder hidden camera detector/locator is the
most reliable and easy to use technology on the
market for making sure that your private actions
are not being watched. Its function is based on
the principle of optical augmentation. This technical
jargon refers to the phenomenon where light reflected
from a focused optical system, such as a video camera,
is reflected along the same path as the incident
light. This means that if a hidden camera is illuminated
and viewed with the SpyFinder technology, then a
strong reflection from the target camera will reveal
its position to the user.
The SpyFinder exploits this phenomenon by using
a ring of ultra-bright LEDs arranged around a viewing
port. When a user scans a room looking through the
viewing port, a hidden camera appearing in the field
of view will brightly reflect the light from the
LEDs.
Operation
While the equivalent of rocket scientists thought
up the SpyFinder technology, operating it is not
rocket science. Simply look through the viewing
port (see photo) and depress the button to activate
the LEDs. Slowly scan areas where hidden cameras
are suspected and look for bright reflected spots.
Remember, most hidden video cameras use pinhole
camera lenses, so the spot you are looking for could
be small.
If you see a suspected camera, move your vantage
point slightly. If the location of the reflection
moves as you move, then this is not a camera. If
the location of the reflection does not move, then
it is highly likely that you have discovered the
optics of a hidden camera.
For example, consider a wall clock that has a
domed plastic cover and a pinhole camera concealed
under the numeral six on the clock face. When the
SpyFinder is used to scan the clock, a reflection
will be noted where the camera is located beneath
the six and a reflection will also be noted from
the plastic cover. However if you move your vantage
point just a little, you will notice that the location
of the false positive reflection point from the
plastic cover will move, while the reflection from
the camera remains under the numeral six on the
clock face.
Maintenance
The only maintenance required of the SpyFinder
is to change the batteries. The device is powered
by two AAA batteries, which will provide over two
hours of continuous on time. To replace the batteries,
the screw should be removed from the back of the
unit. The back cover can then be lifted off to expose
the batteries. The old batteries should be discarded
appropriately and fresh AAA batteries should be
installed with the correct polarity show on the
circuit board.
