If there a way to detect if a unit has seen another unit's HEAD/FACE

[Mastership 0]

I've recently undertaking a bit of a challenge(I'm new to scripting, but getting the hang of it as I practice), and I have been wanting to script an SCP 096 like scenario. I'm sitting in the Virtual Reality world to set up an SCP 096 character, and am having trouble with some scripts. I'd much rather see if the player has seen this unit's(in this case my poor example of 096's) face/head. I would like the detection(script: player distance SCP > 10; player targetKnowledge SCP select 2 > 0; ) to reset faster as well. Just need a bit of a nudge in the right direction, or perhaps alternative ways of accomplishing this goal.
