Plenty of options exist when it comes to home security systems. But at least three things are true about most of them: They are expensive, require a contract, and are limited what they can detect via movement to trip an alarm.
That’s why Denver-based startup Notion created its home sensor: a non-intrusive, cookie-sized device that can be placed on any surface to detect changes in light, sound, and a variety of other elements. A set of the devices, when combined with a Wi-Fi-connected hub, offers traditional monitoring–movement, broken windows, opened doors–as well as the ability to notice subtler aberrations like temperature changes and water leaks. The system sends all of these alerts directly to your phone.
