Our phones are incredibly capable devices — but instead of improving personal safety, they tend to serve as targets for thieves and other nefarious types. The Defender Smart Protection Device changes all of that. This slim, pocketable device connects to your phone over Bluetooth, and should you be approached, with a single button press takes a picture using its built-in camera, initiates a flashing light and audible alarm, and dispenses the highest concentration of pepper spray available to law enforcement. In addition, the picture, your GPS location, and any other authorized information is automatically sent to the 24/7 monitoring service, which can then notify the authorities.
Why spend a fortune on smart light bulbs when the ones you have work just fine? That's the idea behind Emberlight. This intelligent lighting accessory sits between a bulb and its socket, giving you the ability to control any dimmable bulb right from your phone over Wi-Fi. And while this gives you the ability to control multiple lights with a single touch, map out preset lighting "moods", and have the lights turn on based on your proximity to home, each unit also sports Bluetooth LE, giving it the ability to turn lights on or off as you enter or exit a room. Now that's smart.
