Sunrise's main business is signing clients and installing GPS devices to track their vehicles. The users also have access to their own cars' location data. Other companies already offer this service, of course – what makes Sunrise so interesting is that it then goes even further in an effort to get its customer's property back.
First, the company uses closed-circuit television systems that can snap photos of thieves. However, if a vehicle is stolen, then the owner has an easy solution. Sending a special text message immobilizes the car until it can be retrieved. To be drivable again, it just takes dispatching a second message.
As CNN points out, even this immobilization-by-text technology isn't entirely unheard of. But it's still an intriguing example of someone like Macharia seeing a local problem and finding a way to craft a business around solving it. Scroll down for a video from CNN that delves deeper in the story behind Sunrise Tracking.
