Today,　Smart　Home　monitoring　services　have　attracted　much　attention　from　both　academia　and　industry.　However,　in　the　conventional　monitoring　mechanism　the　remote　camera　can　not　be　accessed　for　remote　monitoring　anywhere　and　anytime.　Besides,　traditional　approaches　might　have　the　limitation　in　local　storage　due　to　lack　of　device　elasticity.　In　this　paper,　we　proposed　a　Cloud-based　monitoring　framework　to　implement　the　remote　monitoring　services　of　Smart　Home.　The　main　technical　issues　considered　include　Data-Cloud　storage,　Local-Cache　mechanism,　Media　device　control,　NAT　traversal,　etc.　The　implementation　shows　three　use　scenarios:　(a)　operating　and　controlling　video　cameras　for　remote　monitoring　through　mobile　devices　or　sound　sensors;　(b)　streaming　live　video　from　cameras　and　sending　captured　image　to　mobile　devices;　(c)　recording　videos　and　images　on　a　cloud　computing　platform　for　future　playback.　This　system　framework　could　be　extended　to　other　applications　of　Smart　Home.　©　2012　IEEE.
