Meet Sensor-1: a smart security system that fits in the palm of your hand and detects real time changes in motion to alert you. You can arm it based on your proximity. Sensor-1 does not need a mobile app to work. It logs motion events when you are out of range and can communicate with smartphones, tablets, and laptops.
