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.
