There is a high possibility that you have encountered a camera somewhere in your room, home, or office. However, most cameras are hidden in such a way that you cannot see them, and you only find out about them when you discover a suspicious-looking device in your room or when you are in some other location. There are cameras that are disguised as things like smoke detectors, air conditioners, coffee makers, and more. However, a smoke detector is not the only thing that can be used to disguise a camera. There are many other things that you can use to hide a camera, such as a mirror, a light bulb, a water heater, and even a smoke detector.

It is very easy to use, and it only takes one click to find a suspicious-looking device. After you have found the camera, you will be able to detect its location and see what is happening in the picture.
