How you can Detect Hidden Cameras and Microphones

WSIPI Iguana Private InvestigatorHave you ever felt like you’re being watched? Just want to make sure your privacy is protected? Here are some methods to locate hidden cameras and microphones.

1 The Initial Sweep

1) Conduct a physical search of the premises. This includes a slow and meticulous sweep of the room or building you suspect his compromised.

  • Look around for anything that seems different or out of place, flower arrangement, pictures on the wall out of level or in unusual locations, or lampshades that don’t look right. Look for smoke detectors you didn’t install, look for a speaker that might have a camera in it.
  • Look inside flower pots, light fixtures, and other places where a hidden camera and microphone transmitters can easily be hidden.
  • Look under couch cushions, tabletops, and shelves. Underneath the shelves and tabletops are excellent places for major cameras.
  • Look for wires or cables that don’t go anywhere, such as an appliance or other familiar device. Hardwired, not wireless spy equipment is less common with modern technology, but is still used for permanent surveillance and commercial businesses for loss prevention.


2) Being quiet as possible, listen as you walk through the entire room quietly. Several small and motion sensitive cameras make an almost inaudible click for buzz when they operate.

2 Use Darkness


1) Turn off the lights and look around for any tiny red or green LED lights. A few microphones have the “power on” option indicator light, and if the person setting this device up is careless, they may not cover or deactivate the light.


2) While the lights are off, grab a flashlight and examine all the mirrors. This is more typical for the business environment than a person’s home. Mirrors can be made transparent from one side so a camera can see through, but they rely on the observers side being darker than the area observed in order to keep the other side of the mirror reflective.


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 reflections or glimmers of light back in your direction.

3 Use a Signal Detector


1) Buy an RF signal detector or other bug detector. Truly believe you’re being spied on, by a RF (radio frequency) detector and do a bug 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 that require a spectrum analyzer and an experienced technician to find them.


2) Use your cell phone to pick up an electromagnetic field. Place a call on your cell phone, then waive the device around where you think there might be a camera or microphone. If you hear a clicking noise on a call, it means your phone might be interfering with an electromagnetic field.
