Better also put a second camera facing the eyes to make sure the player isn't looking at e.g. a radar monitor just past the game monitor, or something in their lap. Apparently some cheating streamers will put a camera behind them precisely to show their keyboard/mouse/monitor, but then they'll put a phone or small tablet in their lap or off to the side that has radar/wallhack kind of stuff running on it.

over left shoulder handcam can show head orientation. not sure it's a good idea to require that, or crop it out. head orientation is definitely a part of inputs.

maybe popularize baseball hat with sheet of paper taped on the side? elite gamer apparel. privacy is the meta, after all.

then just include full radar as a part of the game! stealth is overrated in pvp.
