北京文安科技從2003年開始籌辦，2005年正式成立，主要從事智能視頻分析的係統與產品開發。智能視頻分析的核心在於計算機視覺（Computer Vision）和機器學習（Machine Learning）

，簡單來說就是機器看到東西能像人一樣接受信息
，理解
、判斷，最後行動。公司成立後專注於做智能視頻的核心分析，開始主要集中在智能交通這個行業
，研製開發出了車牌識別、電子警察
、智能停車場等產品，並在實際的行業應用過程中
，取得了一致的好評。直至2005年底公司開始進入安防行業
，逐步建立起如金融、零售、軍隊等重點行業解決方案；也ye參can與yu了le平ping安an城cheng市shi建jian設she的de一yi些xie工gong程cheng
