There are many ways to solve many problems quickly and efficiently with the help of modern technologies. For me, the big find was the Ajax security system that allows me to monitor my apartment and what is happening in it from anywhere in the world. This system is multifunctional and allows you to solve many problems when you are away from home. The Ajax line has sensors that use a microwave sensor to detect heat from a heater or use a camera to transmit a photo to a user and a security company to confirm an alarm. Combined sensors react simultaneously to various types of threats, and "curtain" type motion sensors guard the perimeter, allowing you to move freely inside.
