The　paper　proposes　a　design　of　High-Definition　IP-Camera　surveillance　system,　which　has　the　characteristics　of　security,　stability,　cross-platform　transferring　and　short　time　delaying.　The　design,　of　which　Hi3518E　is　set　as　the　core,　implements　the　capturing,　compression　coding,　storing　and　transferring　for　audio　and　video.　In　the　process　of　network　transferring,　RC4　(Rivest　Cipher　4)　encryption　algorithm　is　used　to　ensure　the　security,　at　the　same　time,　the　JSON　(JavaScript　Object　Notation),　which　is　independent　of　the　platform　and　language,　is　adopted　for　exchanging　data　between　platforms　to　assure　that　data　exchange　is　not　relied　on　the　server　platform.　Daemon　is　used　for　detecting　whether　the　device　is　normal　or　not,　to　enable　the　device　has　the　ability　of　self-detection.　The　experimental　results　verify　the　design　is　feasible　and　can　be　implemented　in　many　applications.
