Do you feel like you're being watched? Maybe you just want
to make sure your privacy is protected. Here are some different ways to locate
hidden cameras and microphones.
EditInitial Sweep
1.
1
Do a physical search
of the premises. This involves a
slow, meticulous sweep of the room or building you suspect is wired.
·
Look around for
anything that seems different or out of place, such as flower arrangements,
pictures on the wall out of level or in unusual areas, or lampshades that don't
look normal. Check for smoke detectors you didn't add, look for a speaker that
might have a camera in it.
·
Look inside flower
pots, light fixtures, and other places where a microphone transmitter can
easily be hidden.
·
Look under couch
cushions, table tops, and shelves. Underneath shelves and table tops are
excellent places for miniature cameras.
·
Look for wires that do
not seem to go anywhere, such as an appliance or other familiar device.
"Hardwired" (that is, not wireless) spy equipment is less common with
modern technology, but is still used for permanent surveillance in commercial
businesses for loss prevention.

Listen as you walk the entire room quietly. Many small, motion-sensitive cameras
make an almost inaudible click or buzz when they operate.
EditUse Darkness
1.
1
Turn off the lights
and look around for tiny red or green LED lights. Some microphones have "power
on" indicator lights, and if the person who sets it up is careless they
may fail to cover or deactivate this feature.
2.
2
While the lights are
off, grab a flashlight and carefully examine all mirrors.These can be made transparent from one side so
that a camera can see through, but they rely on the observer's side being
darker than the area observed in order to keep the other side of the mirror
reflective.
3.
3
Search for pinhole cameras in the dark. A pinhole camera might have a charge-coupled device (CCD)
sitting behind a tiny opening in a wall or object. Get an empty toilet paper
tube and a flashlight. Put the tube over one eye like a telescope and close
your other eye. As you sweep the flashlight over the room, pay attention to any
small glimmers that reflect back at you.
EditUse a Signal Detector
1.
1
Buy an RF signal
detector or other bug detector. If you seriously believe you are being spied on, buy an RF
(radio frequency) detector and do a sweep of your room, building, or home.
These portable devices are small, simple to use, and fairly inexpensive.
However, there are bugs that use multiple frequencies in rapid sequence called
"spread spectrum" that an RF detector will not pick up. These bugs
are used by professionals and require a spectrum analyzer and an experienced
technician to find.
2.
2
Use your cell phone to pick up an
electromagnetic field. Place
a call on your cell phone, then wave the device around where you think there
might be a camera or microphone. If you can hear a clicking noise on the call,
it means your phone might be interfering with an electromagnetic field.
·
Can cameras
in TVs be used to watch someone?
o
If a device is wireless connected to
the same signal, the camera can be activated from the TV, transmitting the live
broadcast from that camera.
·
Are squeaky
or buzzing sounds possible signs of hidden cameras or microphones?
o
It's possible, but some cameras work
via cable and power from an external adapter and record on a remote DVR.
Wireless cameras may emit the sound.
