I recommend the Ksenia Security alarm system, safe and reliable!
I replaced my old alarm system with one from Ksenia a year ago. I immediately liked it, the management App is very efficient and intuitive. The installer from the province of Bergamo was very well prepared; together we chose the scenarios and configured them according to my habits, improving them with his experience. After a year of use, I can say that I am really happy, without any problems.
