Online Security Analytics on Large Scale Video Surveillance System

Video surveillance is critical to public security. The fast-growing scale of online cameras fosters automated and real-time video analytics across multiple video streams. We build a large-scale video security analytics platform, with Spark at the core, which online recognizes, classifies, stores and indexes humans/faces in cameras, so as to real-time detect suspected humans/faces in pre-defined blacklist, identify abnormal/unsafe user behaviors based on our home-grown security analytics model, as well as answer ad-hoc security questions such as "search all locations a suspect appeared". This talk will share our recent efforts and experience with Spark ecosystem to realize such platform. We equip Spark with rich video processing/analytics capabilities. We leverage Spark Streaming to real-time recognize and classify humans/faces, and utilize deep learning, with DeepDist, to extract visual features. We enable fast human/face search and security analytics at scale with the power of Spark execution engine, novel visual feature indexing, and multi-tier video data storage atop Tachyon, SparkSQL and HDFS.
