Hi, guys. My parents want to replace their old security system with a new one. But I do not really understand why they are going to buy another old DIY system that is absolutely the same as the previous one. What for? I am trying to prove them to invest in a professional system like Ajax. Could you please share your experience in using such products? As for disadvantages, of course, prices are higher. But, if we analyze the period of exploration and the quality of products, we understand that it this more reasonable to pay for that once than to buy new cheap systems every five years. What are your thoughts about it?
