Hi there! I am going to install a security system in my house. I can't decide which one is better for me. I have already googled a lot. As I understood. there are main two optionsL DIY systems and professional ones. Honestly, I do not want to do anything by myself, but it seems much cheaper. On the other hand, DIY brands do not provide a customer support line. Well, maybe a few of them do. I expect a good quality product at an affordable price. I have also seen the Ajax security company. They seem reliable. Does anyone here know about them? Could you share your thoughts?
