My wallet was stolen in Nanjing 1912 bar. Is there any monitoring in the bar? Is it clear?

it is monitored and can be seen clearly. The surveillance of the bar is night vision. The principle is not clear, not as green as in war games, but as the overall brightness increases, and the black clothes worn by many people show white in the monitoring. . .

However, such a small thing as a wallet may not be noticed by the monitoring.

if you report a case, it seems that it is impossible to file a case if the value does not exceed 5, yuan. Failure to file a case means that JC can look for it or not. So, I don't think we should expect anything. Unless you know someone and ask someone for help, someone will try their best to help you find it.
