How to Find Hidden Spy Camera

Spy/hidden cameras are making the news. The reason is not their special applications in multiple industries and research sectors but the dark side of their use. Hotels, airlines, agencies, and multiple sectors use hidden cameras to spy on people. 

A piece of breaking news from 2019’s South Korean news was about paid live streams available on the internet from motel, hotel, and inn rooms. South Korean police caught four suspects in this case. A spike in the rise of illegal filming from 2012 to 2017 in South Korea is also a serious concern.

The first step is to be aware of your atmosphere. For this, the only requirement is a proper use of your sensory and visual skills. Look carefully into the items mentioned above, also search for spy cameras in the following spaces:

  • Wall Decor
  • Wall holes
  • Indoor plants
  • Roof
  • Electrical outlets and any suspicious cracks.

Do not miss wires. Unplug all the electrical outlets or adapters that are not in use. Walk in the room and listen carefully as motion-sensing cameras create a buzz when operational.

Night Vision Camera Detection

To find a hidden spy camera with night vision, you should look at the working pieces of one of them. Such cameras come with green or red LEDs, which blink in low lights. The LEDs around the camera turn on to compensate for low light to produce clear images. The step-by-step procedure to find a hidden spy camera is as follows:

  • Close the curtains and turn all lights off
  • Check for any light. It might be from camera LEDs. 

This trick works to find both wired or wireless CCTVs. 

  • Smartphones to Find Hidden Spy Cameras


An android or iPhone can detect a hidden camera even if they do not have detectors. There are two ways to find a hidden spy camera with your smartphone including:

  • Call a friend 
  • Install an app

When you call someone while moving around in a hotel room, your call will be interrupted because of the radio frequency interference with the mobile signals. Where you feel this interference, stop and search for a hidden camera. You can also install an app that will display a glow when passing a camera. 

Be Pro! Use hidden camera detectors.

RF signal detectors to multiple camera bug detectors are available to find a hidden camera effectively. Such detectors are available on Amazon and other online or offline markets with a huge price difference. However, they work pretty similarly. When a turned-on detector passes by a camera, it will produce a beep. The point to remember is the inability of RF detectors to find a camera changing its frequency rapidly. Cameras with rapidly changing frequencies are out of the budget of most people. Thus, detectors will serve best for hotel rooms and public places. The spy camera detectors are of the following types:

  • Lens and RF signal detectors: are best to detect listening, bugging, and camera devices in hotel rooms, offices, etc. 
  • Portable detectors are simple in function and best for looking for bugs or cameras in bathrooms and dressing rooms. 

Find Hidden Spy Camera in Mirrors

Mirrors in trial rooms, bathrooms, and other places can be see-through and host spy cameras. To find whether the mirror you are looking into is see-through, place your finger on it and observe its reflection. If there is a gap between the finger and its image, it is a normal mirror, but if both are connected, it is a see-through mirror. From such mirrors, someone can watch you or record you by putting a camera on the other end. 

Actions you need to take after finding a hidden spy camera

  1. Don’t touch the camera as fingerprints on It will help law and enforcement agencies to reach criminals
  2. Step aside from the viewing angle of the camera
  3. Take pictures for evidence
  4. Call law and enforcement authorities

Wrapping Up

With technological advancements, cameras are getting longer battery life, the ability to connect wirelessly, and smaller sizes. The same rise in criminal mindset is also observed.
