Good afternoon everyone who is reading this post. I extremely need your recommendations regarding choosing a reliable security system. Not a long time ago I bought a house, that was quite old, but it was the only variant I could afford. Now I have some money to invest in it. I've already renovated several rooms, changed windows glasses and painted walls. The next stage is to install a security system. I even do not have any fire detectors here. I've heard about the Ajax brand. They produce modern systems to provide a high level of security. Has anyone here heard about them? What security systems do you use in your house?
