Lens detection
Once you find the camera candidate smoke detectors, visually check the smoke detector and look for a small black dot and holes with pins that provide perspective to the lens and visual window.
Like any camera lens, it will be reflective and have a special visual appeal.
Use the mobile flashlight at all angles in a dark room. Reflection of light from any point is an indicator of a hidden camera. If there is a camera lens inside, it will light up. If the smoke detector is placed close enough, you can use commercially available and online glare detectors.
Cell phones can detect hidden cameras. “The hidden camera detector can find a camera anywhere, no matter how well hidden. Just press the button, it captures a light infrared beam, and you can see the reflection of each camera lens. “So this which was hidden from now on can be seen with the naked eye.”
How do you know if there is a camera in your room?
If there is a space between the finger and the image, it is a real mirror. If you touch it with your finger and the image from top to bottom, there will be a hidden spy camera in the mirror. You can also use this trick to find out if there are hidden cameras in your hotel rooms when traveling.
