Ok, here is what i know.
You must have either CHR (Certified High Rank), be PC (Prison Commissionor)+ or have spec perms (Spectator Permissions) which is obtained by buying, or the options listed above.
PC’s with EHR (Elevated High Rank) Perms may exepmt 1 extra person to specate, even if they do not have the requirements.
BoG without EHR may exepmt 1 person to spectate.
BoG+ with EHR may exempt an UNLIMITED amount of people to spectate, even if they do not have the requirements.
CAC with EHR may spectate without spec perms.
Also, I believe that being inside of OC will allow you to spectate, reguardless of spec perms.
I hope this helped !
