In a perfect world, we wouldn’t have to worry about our homes getting burglarized. We don’t live in that world. But there are security systems you can pick up to monitor your home. The Scout Home Security System uses WiFi / 3G to get the job done. It has motion sensors and an arm/disarm panel. You can buy as many as you need to get started. Users can connect to the system using their smartphone. Each of these set you back $120.
