Hi! I also think it's better to buy a good modern security system. It seems to me that you should learn more about Ajax because I have installed this security system for myself and I really like how it works. By choosing Ajax, you get comprehensive protection, easy to manage, protected from unauthorized access and instantly responding to attacks. You can purchase and add additional devices to the system separately. Detectors can be connected with a few taps in the mobile application. I wish you good luck!
