It is trivial to secure windows with plastic foil, glass will literally become bullet proof.

Real problem is if attackers would activate ALL alarms in entire city, night after night. Or your "smart doors" would tip attackers that owner is away from home/

This seems to be a mild deterrent at best.

most doors can be kicked down fairly easily. A window with plastic foil is only as good as its framing.

I guess it depends on who is trying to break in and why.

I remember reading a reddit AMA from a former burglar and he said that these windows did stop him, because he would be looking to get in and out as quickly and inconspicuously as possible and these would slow him down enough that he would try elsewhere instead.

So, for a random opportunistic burglar, they may work quite well, but for somebody determined or someone with more time (eg if you live in a secluded area and they know you're away for long enough), there's always a way in. I've watched enough lockpicking videos to know its not that hard and enough defcon talks to know that lockpicking is rarely necessary. If someone determined wants to get into your home, they will.

Deviant Ollam has some great talks on physical pentesting and simple, affordable solutions to common attacks. You can find them on YouTube.

Even the walls of most houses are fairly easy to get through.

Here's some $50k windows that Nordstrom in Seattle was using that used that film. The windows couldn't stand up to Antifa with hammers, which makes me question the bulletproofness claim. It might not be the same exact stuff that you're claiming, but I'm guessing it is due to the description ("due to their thickness and a protective film that internally self-adheres after strikes or damage"), and that this has happened numerous times to them in the last year and I'm sure they're tired of replacing them and went for the best, strongest windows they could. $50k-70k EACH seems quite expensive for a single display window.

Having worked on those very windows. They are also expensive because of other films and treatments to that glass that filter certain light that damages the items displayed behind it. Also they are just really big pieces of thick glass.
