- Wall holes
- Indoor plants

- Electrical outlets and any suspicious crack.
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 buzz when operational.
Night Vision Camera Detection
To find a hidden spy camera with night vision you should have a 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 for the production of clear images. The step-by-step procedure to find hidden spy camera is:
- Close the curtains and turn all lights off
- Check for any sort of light. It might be from camera LEDs.
This trick works to find both wired or wireless CCTVs.

- 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 you will pass by a camera.
Be Pro! Use hidden camera detectors
RF signal detectors to multiple camera bug detectors are available to effectively find a hidden camera. 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 keep in mind 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 to look 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 can host spy cameras. To find whether the mirror you are looking into is see-through or not, place your finger on the mirror 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 be watching you or recording you by putting a camera on the other end.
Actions you need to take after finding a hidden spy camera

Conclusion
Cameras are getting longer battery lives, the ability to connect wirelessly, and smaller sizes with advancements in technology. The same rise in criminal mindset is also observed.
