据华商报，本周三，中国陕西省的一名4岁女孩在失踪77小时后被找到，而功臣正是一台无人机。韩城市警方在一条深沟中发现了失踪的女孩，女孩除受到几处划伤及脱水外，并无大碍。9月13日，警方发现了一条人员难以进入的深沟，并决定使用无人机展开搜寻。

Police in Nanjing, East China's Jiangsu province established a drone squadron last year. The squadron, consisting of seven drones, is responsible for city patrols, crowd monitoring at major events, chasing crime suspects and disaster relief.
中国江苏省南京市警方在去年就组建起了一起无人机小分队。该分队由七架无人机组成，主要负责城区巡逻、大型事件人群监测、追踪嫌疑人及灾难求助。
The drones, equipped with HD cameras and 4G transmission technology, can reach a height of over 100 metersand fly about 20 minutes uninterrupted. In June, police in Southwest China's Sichuan began to use drones to detect traffic violations, such as illegal parking and occupying emergency lanes. The drones also are used to monitor traffic jams to help direct traffic flow.
这些无人机都配备了高清摄像机，采用4G传输技术，可以在100多米的高空飞行，连续飞行时间约为20分钟。6月，中国四川省警方也开始利用无人机来监控交通违法，包括违停及占用应急车道等。同时，无人机也被用于监控堵车路段，帮助引导交通。
