Anybody know a good, efficient way to lock the camera?

while true do
    wait(0.05)
    script.Parent.CoordinateFrame=CFrame.new(Vector3.new(script.Parent.CoordinateFrame) + Vector3.new(script.Parent.CoordinateFrame.lookVector * 16))
end

This is the closest way I found, except I know there are a few other ways. Basically, I want the camera to lock in one position so the player can't move the camera at all.
