Genuine ways to detect Hidden Cameras and Microphones

Whenever you are using hotel rooms, trail rooms, toilets, bathrooms, changing rooms etc, do you feel like you’re being watched? These days, you’re probably right—spy cams are everywhere, and more are being added every day. Check out some Amazing hidden cameras you would never guess !!

You just want to make sure your privacy is protected? To help you out here are some different ways to locate hidden cameras and microphones.

Do a thorough physical search of the premises – This involves a slow, meticulous sweep of the room or other possible places you suspect. While the camera may be hidden, the lens can only be camouflaged. The ideal places for hidden cameras are smoke detectors, electrical outlets/ plug sockets, behind wall mounted mirrors, clock, lamps, radio, artificial plants, air purifier, paintings etc.

Checking smoke detector – Use a ladder or chair to reach up to the height of the smoke detector. Then take a torch/flashlight and flash the light on the detector. If you see small glass lenses then watch it, the smoke detector has a camera!!

Checking Electrical Sockets – Check every single plug socket/ electrical outlet. Use every single sockets. Try to charge your cell phone or laptop or any other electrical device. If the socket has a camera, it won’t work.

Checking Wall mounted mirror – A one-way or two-way mirror is typically used as an apparently normal mirror in a brightly lit room, with a much darker room on the other side. People on the brightly lit side see their own reflection—it looks like a normal mirror. People on the dark side see through it—it looks like a transparent window. Do a check for these kind of mirrors when using trail rooms, toilets, bathrooms, hotel rooms, changing rooms etc. There are many ways to test whether the wall mounted mirror has got eyes or not. Do several of these tests to make sure the mirror is safe to use.

  • Take a flashlight and flash the light on the mirror. Take the flashlight towards the mirror until it touches the mirror. If you see the light is passing through the mirror or if you can see across the mirror then that mirror has got ‘eyes’.
  • Put the tip of your finger on the mirror. If you see a distance between your fingertip and the image then that means it’s a normal mirror and doesn’t contains any danger. But if there is no distance between the actual finger and its image then beware…that’s a one-way mirror.
  • Turn out the lights. The two-way mirror only works if light is more intense on one side. With the lights off, you will see through a two-way mirror. It may take a few moments to detect the mirror as your eyes adjust.
  • Because they function as windows, two-way mirrors are generally set into the wall; they are not hung on a wall. If the mirror is not flush with the wall, it is most likely not a two-way mirror.
  • Tap the mirror. A two-way mirror will produce a hollow sound like a window because there is no backing on the other side. A regular mirror will sound dull.
  • Test the mirror. Cup your hands around your eyes and place your face next to the mirror. If it is a two-way mirror, you will be able to see something on the other side-unless there is absolutely no light on that side.

Checking objects for pinhole cameras – You should search for pinhole cameras in the books, paintings, air purifier etc. Here are a list of things that could hold an hidden camera inside them. A pinhole camera might have a charge-coupled device (CCD) sitting behind a tiny opening in a wall or object. Use a torch/ flashlight and check carefully. If you find a pinhole sized hole then it might contain a camera. Also search for wiring for wired cameras. If you see any unusual wire coming out from ‘somewhere’ and going ‘nowhere’ then that can be a part of hidden camera. Check the unusual things in the room. Tilted paintings, oddly arranged artificial plants etc and even any kind of pen already present in the room.

Checking for microphones – Your room may also have small microphones, listening all your talkies!! Check for such near drawers, book shelves, paintings and every possible places. Turn off the lights and check for small red or green light. Some microphones and cameras may have such power-on indicators. Don’t neglect them.

Listen for any buzz or click sounds – Listen as you walk the entire room quietly. Many small, motion-sensitive cameras make an almost inaudible click or buzz when they operate.

Using 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. You will hear a magnetic clicking sound if you are over a product that is emitting an electromagnetic field. (Note – This method will work only if the hidden camera or microphone uses an electromagnetic field)

Buy an RF signal detector or an wireless camera 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.

Beware of False Information - There are information spreading virally over the internet that you cannot make calls in trail rooms with hidden cameras due to the interference of fiber optic cable during the signal transfer.

This is utterly false as Fibre optic cables do not interfere with other electronics, and the camera almost certainly will not be using one anyway. Any interference from the camera/cables is likely to be comparable to the amount provided by the webcam in your laptop, and the various cables at your desk, so they would not affect your mobile signal. While a lack of signal may be evidence of a mobile signal jammer, it may also be the thick walls of the room or crappy mobile network.
