How do you make a unit not give vision to it's surroundings?

I want to make the only thing you can see is a region that will be centered to the unit, but I don't know how to stop the unit itself from naturally having sight range. How do I do this?

There's a category called Line of Sight for the unit in the Object Editor.
Just set the value to something like 0.

Thank you! I guess I didn't look hard enough..
