Hello dear forum community,

Due to recent events, I would like to ask how new and experienced homeowners think about burglary protection and what measures they have installed or are planning to install. Also, whether anyone has had good or bad experiences with certain products.

Now, regarding the current situation: last week, there was a break-in at our immediate neighbors’ houses and then at two houses behind us.

In one case, there was an attempt to lift the front door, but the triple locking mechanism held... then the intruder tried the terrace door (security level WK1), which gave way.

At the other house, an attempt was made at a small window behind the house (WK3), which also failed, and then at the terrace door (WK3). Here, the roller shutter was torn off and the triple glazing was smashed.

In summary, jewelry, electronics, and all small valuable items were stolen, as well as coats and similar items. Larger items were left behind, but everything was thoroughly searched and violently broken into.

The day before yesterday, another break-in occurred a few streets away… all around dusk, about 5-6 pm.

We have WK2 windows, and I will now upgrade them to WK3 (already ordered). But what about the glass? I won’t be able to replace all panes with laminated glass, it’s just not feasible. Has anyone had experience with films that are applied from the inside (300 mil)?

Besides that, we have video surveillance all around... We are now installing ten 20W LED floodlights around the house, which turn on when motion is detected and stay on for a while (directed away from the house).

Additionally, a siren will be installed on the roof, connected to the KNX alarm system, which will activate in case of glass breakage or unauthorized window opening. (I still have to buy the glass break detectors).

For the large windows, I have also ordered rod locks because the weak point is in the middle where there is no central bar.

Well, then you can never, ever open it. I’m not sure if you want to make such final decisions. The savings will probably be minimal, right?

For me, it was more about the appearance than the savings. Without a handle, in my opinion, it just looks better.

Not just the handle. For us, there are two large window sections, which, due to their design (laminated safety glass, soundproof glazing), could not be made as a single unit for opening, but only as two separate sashes.

On Wednesday, our new P4A glass finally arrived, and the windows now have mushroom cams installed wherever possible.

What is that small black thing? An alarm contact?

Yes, a reed switch... misused for:

  • Alarm system
  • Opening of roller shutters / blinds
  • Indicating the window status (open/tilted/closed) there is another one below

Interesting. I'm too clueless to understand everything that is possible.

We also have contacts on everything that can be opened.
It is also possible to distinguish, meaning to display the status of the window (open/tilted/closed), and this can then be connected to an alarm system.

I didn't know it could be combined with roller shutters.
