How to detect hidden cameras and microphones?

Posted by Dante on Feb 12th 2020

Cameras and microphones can be hidden in all kinds of spots to spy on people. In most places, it is illegal for anyone to record without providing proper notice, but that does not mean that you are not being kept track of. If you have a feeling that you are being tracked, conduct a physical search using the technology available here to detect hidden microphones and cameras. Let us have a look how you can detect these recordings.

Conducting a Physical Search

1. Listen for a clicking noise or quiet buzzing to detect any recording device. The recording hidden devices are designed in a way that they stay discrete, but many still emit a tiny sound while operating. Keep the area in pin-drop silence and walk around to listen out for a slight clicking noise or any buzzing that may come from a hidden microphone or camera.

2. Investigate the smoke detectors and different electronic devices. Surveillance cameras being nano-sized can be kept hidden inside devices that require electricity like a smoke detector. Bring down your smoke detector from the ceiling and search for a camera or microphone within. Check your lamps, speakers, and other devices for signs of meddling and tampering.

3. Search for decorations that are out of place or seem strange. The most common way of hiding a camera or microphone in a room is by placing it in something inconspicuous like a vase of flowers or a teddy bear or something that always stays in the room. Look out your suspicious decorations like visible lenses or glassy surfaces that may indicate hidden cameras.

4. Look for peculiar wires that lead nowhere. There are some surveillance devices used for a short period, and they require some power supply. Check your power outlet and electronics for wires that lead into things that don’t need any power or wire that you don’t recall.

Search for Electrical and RF Signals

1. Sweep the area or your whole room with an RF detector. You can scan for frequencies using an RF detector, that transmit from microphones and hidden cameras. Get your RF detector from and sweep it around the places you think are bugged. The detector will crack or make a beep sound when it receives any radio frequency.

2. Carefully listen to any interference when you are on a call. Microphones and hidden cameras tend to make an electromagnetic field because they transfer data. When you make a call using your mobile phone, take a walk around the area while talking. If you suspect any clicking, buzzing or cracking on the phone, it may be a signal that you have entered in a field where any surveillance device may reside.

3. Use a smartphone or digital camera to search for infrared lights. Many digital and smartphone cameras have the ability to see infrared light that the naked eye is not able to spot that can be used for recording purposes. Scan the camera around the area and check through the display for any unanticipated flashes or light source that may point out a hidden camera.
