As useful as Nest's Dropcam is, it isn't the best looking home monitoring camera. Still, there aren't many of them that do a better job design-wise. Silk Labs, a startup founded by Mozilla's former CTO, Andreas Gal, sees this as an opportunity to offer something different. Enter Sense, which is similar to Dropcam in functionality but also comes with a few notable differences. For example, it's said to be smart enough to recognize multiple faces; that can be used to let you know if it thinks a stranger is in your home, or play music based on a particular individual's taste.
