@verticalspin is correct. I worked alongside one of the Capitol 429s for several months at night this past season and they don't have cameras. The BBC article is written by someone who's never been near a fire and full of inaccuracies.
NVGs help in seeing through smoke up to a certain point. Just like shallow fog, they can get you in trouble and will slowly shut down the thicker the smoke gets. This is why adopting a scanning technique that includes looking under the goggles will help identify areas of heavy smoke.
