You have to sign a document before you get equipment. Part of that document is you acknowledging that you read another document that outlines what you can and cannot do with company equipment and what the capabilities of said equipment are. We even tell people to close the physical camera shutter on the laptop whenever they aren't on a video call if they want to ensure privacy. There is also a code of conduct document they need to read and sign. Using company property for lewd acts and to conceal adultery broke a number of agreements.
