I used to be very skeptical about security systems because it seemed to me that they did not work and were not needed at all. But when I was robbed and almost my entire house was taken out, I immediately had to start watching the alarms and after reading the reviews, I stopped at Ajax because everyone spoke positively about it. I ordered it for myself, too, and to be honest, I really liked how it works and liked that you can also separately purchase sensors that are responsible for fire and flooding. I wish you good luck!
