Major introduction

Using engineering and technology to solve public safety challenges, making cities safer and investigations more efficient.

Program overview

Public Security Technology is an applied discipline under the engineering field. Simply put, it's about "using technology to protect safety." At the graduate level, you'll learn how to use tools like computers, electronics, chemistry, and biology to prevent crime, investigate cases, and handle emergencies. Core courses include: Network Security and Forensics, Video Image Analysis, Explosive and Drug Detection, Big Data Police Analytics, and Security System Engineering. Chinese universities have strong practical features in this field—many labs collaborate directly with public security departments, giving you access to real cases and the latest equipment. It's ideal for students who are hands-on, logical, and interested in crime-solving or safety systems, especially those who enjoy applying technology to "catch the bad guys" or "prevent risks."

Major prospects

现在全球都在搞智慧城市和数字治理，公共安全技术越来越重要。中国正在大力推动“科技强警”，从人脸识别到无人机反制，从网络诈骗追踪到交通事故重建，都需要专业人才。国际学生学这个专业，回国后可以参与本国警务现代化，或者进入跨国安全公司。另外，中国在安防设备、视频监控、大数据警务方面的经验很丰富，这些技术在很多国家都有需求。如果你对网络安全或电子取证感兴趣，这个方向尤其热门，因为网络犯罪是全球性问题。

Career prospects

毕业后出路挺广的。最直接的是进公安或司法部门的技术岗位，比如网安支队、刑侦技术科、物证鉴定中心，做电子取证、痕迹检验、视频分析等。也可以去安防企业（如海康威视、大华）、网络安全公司（如奇安信、360）、司法鉴定所，做研发或技术支持。还有一部分人进高校或研究所搞教学科研。薪资方面，在中国，体制内岗位起薪约8-15万人民币/年（含福利），企业岗位10-20万，有经验后更高。国际学生如果回国，技术能力会很有竞争力；如果留在中国工作，需要留意签证政策，部分岗位可能要求国籍。
