That only applied to basic Sharingan genjutsu. More advanced ones like Tsukuyomi needed eye contact. I guess Shisui doesn't need eye contact for Koto just because he's so good at genjutsu. For FOV, it's safe to assume he needs to be able to see you clearly, you can't just be some blurry figure in the distance. That's quite possible but I feel like Madara would be able to react to that. EMS Madara is more likely to get caught than TTJ Madara.
