How Do Put A Players Camera In FirstPerson?

Just like any horror game, you need a FirstPerson script. But the problem is: how do I do that? Any Suggestions?

I believe this will work.

game.Players.PlayerAdded:connect(function(player)
    player.CameraMode = "LockFirstPerson"
end)

while wait() do
if script.Parent.Parent.Character.Humanoid.Health~=0 then
script.Parent.Parent.CameraMode = 1
else
script.Parent.Parent.CameraMode = 0
end
end

This script is to reset people's cameras to normal on death and FPS on respawn, THIS MUST BE PUT IN A LOCAL SCRIPT UNDER STARTERGUI OR STARTERPACK.
