Security cameras are one of the easiest-to-justify devices when it comes to adding connected devices to the home. But simply shooting footage is not all that helpful. What you want is a camera that can alert you when there's unexpected activity, let you look at that activity in real-time and store the footage easily just in case you need to let the cops know there's been an intruder. The Netatmo Welcome ticks those boxes but needs just one more feature to bring it closer to perfection.
