What are the pre-purchased items of the security department of the property company?

You take a pen and notebook to look at the booths in other communities, first give cigarettes to the security guards, then talk slowly and write down everything in their booths. For example, patrol sign-in book, visit registration, electric fan this summer, winter heater, flashlight, baton, walkie-talkie, telephone, water shoes, raincoat, uniform water dispenser, etc ... almost enough, hehe.
