Can I sleep at night when I am a security guard at the isolation point?

Generally speaking, night guards are not allowed to sleep, after all, they have to stand guard at night.

But the security in general places is not so strict. After all, it is not a militarized base, nor is it a guard for important materials. So in general, night guards will take a nap.

They will wake up at a fixed time to patrol, but they will not sleep soundly, because people have the habit of being sleepy at night. So people who work at night usually take a nap. As long as things are not delayed and people's lives are not affected. People generally don't care. After all, people understand each other.
