How many jobs are there in security inspection?

I passed the security check at Beijing airport, where there is a special plane building security check. The security check of VIPs in the venue is also called lily security check, personal security check, passage security check, airport perimeter security check and off-site property security check. There is also a special type of work, that is, the police assistant, which belongs to the security company, but the command is in the airport branch.

The types of security inspection are divided into starter, hand inspector, verifier, package opener, guide and flight area guardian. Property security inspection is not actually a security inspection, but he belongs to a security company, and I don't know if it is within your scope.
