From VOA Learning English, this is the Technology Report.
Kenya is East Africa's largest economy. Its capital Nairobi is growing quickly. But so is the city's crime rate -- the Nairobi Metropolitan Crime Observatory says thieves steal an average of 10 cars each day.
Kelvin Macharia has invented a tracking, or following, 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 chief executive officer 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 surveillance system uses a computer or mobile phone to tell owners where their car is. Mr. Macharia says if a car is stolen, the owners can find it using his tracking device. Owners are able to send a command 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 devices. When he was satisfied with the design, he outsourced the building 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 Nairobi have targeted these vehicles. Mr. Wanga bought trackers for each of his vehicles. The trackers cost $250 each. He says the tracker tells 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.

这里是美国之音慢速英语科技报道。
肯尼亚是东非最大的经济体，其首都内罗毕发展迅速。但该市的犯罪率也增长很快，内罗毕都市犯罪观测站称平均每天有5起盗车案。
开尔文·马查里亚发明了一种追踪装置，这种装置使用电脑和无线科技来让车主知道他们车的位置，如果被盗还能找到车。马查里亚今年才24岁，但他已经是Sunrise Tracking公司的首席执行官。
他2012年开始从事这项发明，他使用自己积攒的300美元，改善了现有的寻找被盗车辆的系统，他的监控系统使用电脑或手机来告诉车主其车在哪里。马查里亚说如果车被盗，车主就能使用追踪装置找到车。车主能通过短信向车辆发送指令，指令能立即让车辆停止行驶。专家称这就显示了使用移动技术的安全解决方案的神通。
马查里亚利用在肯尼亚可获得的材料制作第一个追踪设备，当他对设备感到满意时，就让中国一家工厂负责设备的外包生产，他说他的公司现在价值10多万美元，已有100多家公司客户。
托尼·万加就是他的一位客户，他拥有三辆小巴的士，内罗毕的盗车贼现在瞄准了这种车辆。万加为他的每辆车都购买了这一装置，每台售价250美元，他说追踪设置能告诉他车辆在哪里，他说当汽车上安置这种追踪器后，他就能坐在办公室里跟踪车辆的行踪。
马查里亚继续开发其他的安全产品，其中包括汽车警报器和隐藏在钢笔中的摄像头，他说他在设计一种无线安全摄像头，能储存长时间的视频信息。
马查里亚希望他的科技发明能给客户他们想要的安全保障。
