There's always a number of these stories after every disaster.
Back a few decades, I looked into firefighting (until it became obvious that, being a white male, that option was unlikely to happen in less than 5-10 years).
Before that point, I regularly perused EMS and fire science magazines, and became aware that one can purchase the exact same type of fire monitor you see on lots of fire trucks driving down the street. And you still can.
For the unaware, a fire monitor is not a video camera, it's the directable water cannon nozzle assembly, used on water trucks and fireboats as well.
They can be mounted anywhere (I'd pick the center of the roof, personally) and rigged to run off of one's pool, pond, or well, provided you also have your own generator power.
The can put out over 1000gpm for a hundred feet or more, and they run a couple of grand@. As opposed to your house, which in the hills and canyons of fire areas, runs $300K-$1M.
That's a real economic poser there.
And it's one helluva lot smarter than trying to fight 100' flames with little vinyl garden hoses.
Trimming trees and brush well away from the house is even cheaper.
Especially because both ground and air fire crews triage houses in the path of these fires, and if they see one that's savable, they'll make the effort, but if yours is an overgrown tinder trap, they'll write it off mentally as a total waste of their finite resources, and after that, you're screwed.
But most of the dumbfucks in the fire-prone hillsides are in their cosmic bubbles more often than not, and don't do the legwork before hand, and then get burned out.
Except for the few smart guys, like the two in this video.
(And this sort of thing doesn't apply to entire small towns amidst fire country, where you have fewer options, nor to renter tenants within them, who effectively have none. When the entire town burns down, you're simply SOL. Have a "go" plan, and stick to it.)
But it astonishes me that people who do have a choice will purchase a home on acreage, and spend years of salary for the view, but not invest a couple of paychecks, and some forethought, to prevent an entirely avoidable loss of everything they own.
Their fire insurance premiums should be 10-20% of the cost of their house, annually.
Triple that for any nimrod who still has a wood shake roof.
Unless they take the steps these guys did.
Learn not to burn.
