Smart smoke detectors not only notify you of danger indoors, but also at any location. That way, you always know what's going on at home and you can have your smart cameras turn on automatically so you also have footage of what caused the fire, for example. That's because they're linked to your WiFi network. Via an app on your smartphone, you'll receive a push notification that a hazard has been detected. This way, you know what's going on at your home, no matter where you are. You can take action right away.
