Hi guys! Could you please tell me the difference between any CCTV system and the Ajax system – https://ajax.systems/. I am looking for a professional security system to install in my new house. I always thought security systems and CCTV systems are the same. After I watched YouTube videos and read a lot of articles about Ajax, I understood that this professional system that produces a high-quality product with modern features does not even have cameras. Honestly, I do not understand their policy. Security system without security cameras. But I like their devices. Do you think it worth it to choose that brand?
