Since　surveillance　system　plays　an　important　role　in　security　management,　IP　(Internet　protocol)-based　surveillance　systems　are　widely　used　by　now.　The　emerging　Internet　of　Things　effectively　promotes　the　development　of　multimedia　network　techniques,　in　which　applied　to　intelligent　surveillance　is　one　of　the　most　successful　applications.　This　paper　deals　with　an　intelligent　surveillance　system,　which　includes　entrance　guard,　SMS　(Short　Message　Service)　alert,　network　and　video　analysis　modules.　The　key　technologies　of　this　system　include　RFID　(Radio　Frequency　Identification),　IPv6　-　IPv4　exchanges,　and　the　SMS　auto-warning　technology.　The　surveillance　system　has　been　successfully　applied　to　the　telecommunications　field,　and　is　also　an　IPv6-based　application,　completely　integrated　to　RFID　technology　and　SMS　(Short　Message　Service)　alert　module.　The　simulation　results　show　that　the　system　achieves　the　target　of　real-time　tracking　and　detection.
