ᐅ Protect windows from break-ins using external metal bars or security grilles

Hello everyone,
I have three wide but not very tall basement windows without shutters. A potential burglar, if slim enough, could break the glass and enter my townhouse through these windows. I want to prevent this in advance, hoping that such a burglar will move on to my less-liked neighbors and empty their place instead.
The house has external thermal insulation, which means the windows are recessed about 20 cm (8 inches) inward. I don’t want to simply screw a grille onto the exterior wall, as that looks too much like a prison. My plan is to saw a typical stainless steel handrail (maybe 8 cm (3 inches) diameter) and place it centrally in front of the window, horizontally or with two vertical bars.
Is this a good idea? What is the best way to install it? Should I use a hammer and chisel to remove the insulation and plaster/masonry, lay the bar inside, and then cover it with plaster so the bar can’t be removed? Unless, of course, the slim burglar also has a long chain and an all-wheel-drive SUV, then none of this would help.
I hope you understand my problem and would appreciate your advice!

...that all sounds very amateurish!And that’s exactly what it is.

Why not from the inside? That way you wouldn’t have to damage the insulation/façade in specific spots.As Gartenfreund already said, doing it from the inside would be impractical.

Hello MaxPower90
I planned the security of my house in cooperation with the Police Advisory Service.That’s also a very good idea!
I’ve attached a photo of the corpus delicti here. I was thinking I could drill a larger hole with a big drill at the spot where I marked the red dot. I would do the same on the opposite side, but a bit deeper than necessary. Then I would insert the steel rod from the outside, center it, and fill both sides with cement.
Without having measured yet, there should still be enough solid material on the outside before the thermal insulation starts, so that no one could "pull out" the rod.
What do you think of this plan?

Yes, that definitely sounds feasible.

Cutting a typical stainless steel handrail (maybe 8cm (3 inches) in diameter) and placing it centrally in front of the window, either horizontally or two vertically.Hmm, I cut through the handrail with a manual metal saw in under 60 seconds.
I’ll do the same on the opposite side, just a bit lower than necessary.How far should the pipe go into the wall on both sides? How do you plan to get cement behind the pipe? Otherwise, I could just push the pipe back into the hole, and the contact between pipe and cement won’t be very good.
The first step should be to ask someone who knows about this (like the police).

Otherwise, I could just push the pipe back into the hole, and the contact between the pipe and cement won’t be very secure. Maybe about 10 cm (4 inches) on each side. I’ll pack it in as well as I can using a trowel. Once everything has cured, I’d say the pipe won’t move much anymore. Cutting it through is of course possible, but that makes quite a lot of noise at first. Since I live in a terraced house in the middle, hopefully the neighbors will notice. Also, the glass would have to be broken in the process.
Contacting the police is a good idea anyway.

Would you use plaster, cement, or what would be best?
