The area I want to move in is known for its heightened percent of home invasions and burglaries. So I don't know, maybe it is excessive. I just don't want my life savings to fall into the hands of a random burglar.

Why keep your savings at home? For anything critical I use a safe deposit box.

My bad for using bad figure of speech. Of course most of my savings won't even be physical (bank / cryptocurrency / investments etc.) -- I meant that I'll have all my possessions there (expensive computers, TVs, furniture, kitchen tech, what have you) and I would like to avoid having them stolen while I am grocery shopping in the nearest city, you know.

Is law enforcement in the area such that cameras would be a real deterrent?

No clue. But I am accepting another commenter's idea that having very visible cameras (on purpose!), solid fence and 1-3 guard dogs should be enough to deter 99% of the potential home invaders.

To me excessive would be automatic tracking turrets with really nasty things mounted on them. I recall someone made one that fits in a briefcase and uses paintballs. It had something like 90% accuracy on fast randomly moving targets. But for some people that might not be excessive, probably depends on the circumstances.

Reminds me of the hotel scene in the book "Altered Carbon". The Netflix series did a good job visually with this scene.

That is a great show and I agree, that hotel is a perfect example. I really hope they keep the show going.
