Good day to all. Tell me, is there a reliable security system that I can use to ensure that my home is safe while I'm in another city? I've heard several reviews about Ajax and Frontpoint. However, the Internet always writes a lot and not still to the point. I'm not sure what I should choose, as I don't understand this issue well enough. Are there any people among you who use such systems? Can you recommend a reliable company with a mobile app that you have tried for yourself, maybe?
