"When the main character talks to the camera, is that 3rd person or another technical term for point of view?"
No – it is neither of those things.
"Point of view" usually refers to the point of view of the narrator, which can be omniscient, limited third-person, first-person, etc.
If a character breaks the fourth wall in a film – I emphasise "character" because I am assuming he doesn't stop being the character and become omniscient, or, even stranger, become the audience – then he's speaking. This is different from dialogue, different from a soliloquy too in that he's not speaking to himself, and it's different from introspection, but it's still a character speaking, and I'm assuming (see preceding sentence) he is speaking in his own voice. He may be telling us what happened yesterday, he may be speaking from the future and saying "At this point, I didn't realise X", and he may be addressing us as "you". But he is still a character. When he is speaking we don't hear the voice of a narrator, and the idea of "Nth person narrative point of view" doesn't apply.
That the fourth wall is being broken doesn't tell us anything about the narrative point of view. There may be no explicit narrator, given that this is a film. If there is an explicit narrator, perhaps only heard in the soundtrack, it could be a third-person one, or it could be a first-person one.
