Why do hotels routinely check and take photos?

Conduct investigation and evidence collection.

There are generally two situations in police rounds, one is the need to detect criminal cases, and the other is to conduct routine inspections of hotels, nightclubs and other places according to the Law on Public Security Administration Punishment to maintain social order. The main purpose of taking photos is to investigate and collect evidence and archive relevant evidence materials. The routine patrol inspection of the police is allowed to take pictures. Taking photos or taking identity documents is only for evidence collection, scanning to see if it is consistent with the system data.

As hotels and restaurants are high-risk areas of all kinds of criminal cases and one of the key places that the police pay attention to, it is necessary to conduct regular routine inspections. As long as it doesn't violate the law, it won't have any adverse effects on your daily life in the future.
