Not only does the Netatmo have built in person detection, it also has facial recognition technology. That means that it can differentiate between an intruder, your dog, and your family. It can recognize up to 32 faces!What I like about Netatmo’s facial recognition technology is that it learns over time who should be in your house and who shouldn’t. You’ll only be notified when the camera recognizes someone it hasn’t seen before, saving you a lot of time checking the app. Instead, you’ll be notified via your Apple Watch or cell with the unfamiliar face itself. I love how instantaneous the notification is. As soon as an unfamiliar face comes into the camera’s line of vision, I’m notified and can decide how to proceed from there. But the coolest feature of the Netatmo’s artificial intelligence is its integration with Facebook messenger. Just as you would type to a friend, you can ask a Facebook bot when people entered and exited your home. I love this feature because it takes something that you probably already use, Facebook messenger, and links it with the Netatmo Welcome to create a seamless customer experience.
