Do you mean in terms of camera viewpoints?
Because I don't think a '2nd person camera' is actually possible.
You would be totally correct.

In this context, "person" is a term borrowed from grammar/linguistics by way of narrative theory, but it's an imperfect fit, because the grammatical and narrative definitions don't map perfectly onto the "camera perspective"/"viewpoint" domain.
Grammatically, "first-person" indicates word forms that refer to the speaker, "second-person" to the hearer, and "third-person" to those not part of the conversation.
These terms get extended to narrative on the basis of the pronouns used to refer to the main character, and thus relate to the role the main character takes in the "conversation" with the viewpoint "character" as the speaker. Thus in "first-person narrative" the main character is the speaker, and therefore also the viewpoint character; in "second-person narrative" the main character is the hearer, and in "third-person narrative" the main character is neither the speaker nor the hearer.
Now let's look at the case of camera perspective, which is to say viewpoint. If you notice in the section above, there are only two relationships between "viewpoint character" and "main character" - either they are the same person, or they are not. In other words, second-person and third-person viewpoints are the same thing. The difference between second- and third- persons is a matter of who the narrative is being told to, not who's doing the telling.
In other words, if you're seeing the game through the player character's eyes, it's first person, but if you're actually seeing the player character it's third-person -
and it's still third-person even if you are looking at the player character through someone else's eyes.
