The hotel saw the white spot with the camera. Is it a camera?
Turn on the radio of your mobile phone and walk around the room slowly with your mobile phone. If there is interference, it proves that there is a radio signal. The stronger the interference, the closer it is to the interference source (the transmitter of the camera).
Wired cameras are difficult.
There is also a general method:
Turn off the lights and darken the room. Then take the flashlight next to you. If you encounter something that reflects light (such as the lens of a camera), it will turn white.
In addition, the general camera consumes a lot of power, so many of them use the power supply in the room. So, if you are still worried, just turn off the switch. (This is not absolute)
