Alarm system: pros and cons

Then I would still have something for self-defense on hand... pepper spray or something like that... The police hurry anyway when they know you are still in the house....

Ok I have it anyway now, because he is lurking for me....But what kind of alarm system should I take there?? Can you recommend one to me??

I would definitely choose a slightly more expensive one.... They are also the safest.... I wish you all the best in any case.... Take care of yourself...

Yes, thank you very much for all the information.....I will take care of myself and soon a whole police station will do as well.....Thank you

Hello,
I am also considering whether an alarm system might be useful.
There have been several break-ins in the neighborhood recently.
Or whether it is better to better secure doors and windows.
While searching online, I came across this book:

-Selbstschutz- Einbrüche wirksam verhindern
by Siegfried F. Hübner; ISBN-13: 978-3941538504

According to this book, it is probably more sensible to focus on passive security and better secure doors and windows.
An alarm system is of course cheaper than new windows and doors.
The house is from the 60s and the windows/doors are from around the mid-80s.
What to do now?
Best regards, Jenny123
