If the aviation industry is one thing, it is stubbornly conservative. Took like until about a year or two ago to finally get unleaded fuel approved for GA piston engines, and most of the piston engine designs in new production are like over half a century old because no one wants to go through the effort to certify any modern engine for aviation...
Yeah, I know, and I know about the leaded gas situation.
The thing about cameras, though, is you can buy an HD dash cam for $100 that records in a loop. Buy it, plug it in, and point it at the runway. It doesn't need anything beyond a wall socket.
If I was an ATC sitting in the tower, I'd probably just install one myself.
TBH there's enough of a "planespotting" hobbyist community who would love to have good quality camera footage of takeoffs/landings to probably finance great quality cameras at all major airfields covering all the runways/ramp areas/etc. just from ads from streaming. Also insurers (I actually work with a bunch of the guys at Lloyd's syndicates who do hull insurance for aircraft; I can ask them in a few weeks how much this data would be worth to them. For ramps, it would be "who backed into my aircraft while it was parked" issues. I worked on an airbase where someone drove a pickup truck into a super high end "one of two" high altitude long endurance drone, destroying 50% of the US Government surveillance capability in theater for about 4 months...)
I wonder if you could get an additional market of "plane X taking off from/landing at airport Y at time of day Z in weather W at time of year U" clips for TV/movies, or if they already have enough of that stock footage.
