Turn off the lights and look in the mirror with a mobile phone camera in the hotel. Will a red dot appear like a camera?
Yes, pay attention to many precautions. Turn on the camera without blinking after turning off the lights, and then slowly move the phone to scan the whole room to see if there is any red light or blue light. Then, if you find it, go and see if there is one. This light may be a camera, so you need to check it yourself. Sometimes the TV remote control also has light. Anything that emits infrared rays will glow under the lens. I hope it works for you!
