Huawei built Africa's first modern "Safe City" system in Kenya using new information and communications technology. As part of this project, Huawei deployed 1,800 HD cameras and 200 HD traffic surveillance systems across the country's capital city, Nairobi. A national police command center supporting over 9,000 police officers and 195 police stations was established to achieve monitoring and case-solving. The system worked during Pope Francis' visit to Kenya in 2015, where more than eight million people welcomed his arrival. With Huawei's HD video surveillance and a visualized integrated command solution, the efficiency of policing efforts as well as detention rates rose significantly. The regional crime rate has since dropped by 46%. In 2016, the number of international tourists travelling to Kenya rose by 13.5% year-on-year. Even Kenya's president spoke highly of this project on Facebook.
