You may not care much, but the phenomenon of small hidden cameras is spreading widely and without

 making any media fuss. The phenomenon of using spy cameras locally began in late 2018 at the most

 all corners of the room so that it is dark, and this will enable you to see the lights, but only in the event

 that the camera works in infrared (used for lighting in the absence of light, capture it The camera is not visible to the eye.)
