Does the evidence taken by pinhole camera in dormitory count?

Generally speaking, pinhole camera is an electronic device that is forbidden by the state. It is illegal to install and photograph a dormitory without the knowledge of others. However, in order to obtain relevant criminal evidence, after filing with the public security organ and obtaining the installation license, it can be filmed. The evidence photographed is also very convincing. (It is worth noting that pinhole cameras need to be obtained through proper channels and cannot be bought or sold privately. If it's just to prevent the dormitory from being stolen, it's suggested that you inform your roommate and get his consent to buy an ordinary camera instead of a pinhole camera. )
