Passive Perception is an excellent mechanic and solves the problem that many game systems have, namely, if everyone in the party always rolls, then nothing will ever be hidden, as with the dice variance, someone will roll high. The hobbits can't hide on the mountainside if 1000 passing orcs each get to roll to check to notice them. It solves a lot of problems.
You would just roll a group perception check for the orcs.
What problems does PP actually solve? If you look closely, you will find it only causes problems, imo.
