Is there a surveillance camera in the cinema lovers' seat?

Cinemas are basically covered by cameras, and their cameras are infrared, so you can see clearly, and there will be someone on duty in the screening hall, so you should pay attention to your manners in the cinema, because you may be photographed. In order to avoid potential safety hazards, everyone should take photos.

Cinema introduction:

A cinema is a place where movies are shown to the audience. In the early days, movies were shown in cafes, teahouses and other places. With the progress and development of movies, there have been cinemas specially built for showing movies. The development of movies-from silent to stereoscopic, from black-and-white movies to color movies, from ordinary screens to wide screens to dome screens and circular screens-has greatly changed the shape, size, proportion and acoustic technology of cinemas.

The cinema must meet the technical requirements of film screening and obtain the good visual and auditory effects it should have. The film became an argument after dinner.
