Are there any differences between smart home systems and home security systems? I remember times when home security was provided by several independent products like fire alarms. And CCTV systems also worked separately. Now I have an Ajax home security system at home and I wonder how many opportunities it has. According to your picture, I would say that I have both systems in one. I mean, all my devices including cameras work together. And I have an access to them through my phone application. Technological progress goes further and further day by day. So, we don't have to spend much money to secure our houses.
