Kenya has east Africa.s largest economy. Its capital city is growing quickly, but so is the city.s crime rate. Thieves in the capital steal an average of 10 cars each day.Kelvin Macharia has invented a tracking device that uses computers and wireless technology to help owners know where their cars are, and find them if they are stolen. Mr. Macharia is just 24 years old. He is the CEO of Sunrise Tracking.He began working on his invention in 2012. Using $300 from his savings, he improved a system that was already being used to find stolen cars. His smart anti-theft system uses a computer or a mobile phone to tell owners where their cars are. Mr. Macharia says if a car is stolen, the owner can find it using his tracking device. The owner is able to send a command signal to the vehicle through a text message. It immediately stops the car from moving. Experts say this shows the power of security solutions that involve mobile technology.Mr. Macharia used material available in Kenya to make his first tracker device. When he was satisfied with the design, he outsourced the making of the device to a factory in China. He says his company is now worth more than $100,000 and has more than 100 companies as clients. Tony Wanga is one of those clients. He owns three minibus taxis. Car thieves in the capital have targeted these vehicles. Mr. Wanga bought trackers for each of his vehicles. The trackers cost $250 each. He says the trackers tell him where his vehicles are. He says when the tracker is placed in one of his vehicles, he can follow its travels as he sits in his office.Mr. Macharia continues to develop other security products. His other security products include car alarms and a camera hidden inside a pen. And he says he is building a wireless security camera that will be able to store video information for long periods of time.Mr. Macharia hopes his technological innovations give his clients the security and safety they want and need.
