A smart alarm system uses the WiFi network to send its notifications. Smart alarm systems can be linked to an app, which you install on your smartphone or tablet. Through this app, you get a message when the alarm detects activity. Smart alarm systems can often be linked to more devices than motion sensors, such as IP cameras or smart lamps. If you receive a notification of the alarm, you can view camera footage directly in the app with a smart alarm system. Due to the internet connection of the alarm, it doesn't matter where you are.
