I would like to ask for a piece of advice. What security systems for your houses do you guys use? Can you name me several brands that produce quality products, such as fire detectors and motion sensors? I want that to be modern. I mean, I would like to control it remotely and see what is happening in a backyard at the moment. So, it seems I also need cameras. By the way, I have heard about Ajax. So you not if their system worth it? I will be very thankful if you name me at least two companies I can call.
