There is a company that we discuss recently because of their elegant embedded NVR device. I just talk about the private cloud and public cloud roles in the surveillance system in previous article. http://frankuo.blogspot.tw/2013/02/pure-public-or-hybrid-cloud-for.html Smartvue’s product architecture is a case of the hybrid cloud. Let’s see the whole system they define. We can take S9 server as the private cloud server for local storage and playback. If we remove this part, the total system become a pure public cloud type. Although the pure cloud system is simpler, there are still some limitations at this moment. Smatrvue let the high resolution video to be stored on the local server and high or low resolution video can optionally be put on the secure cloud. The reason is obvious that the network environment of LAN is still much clean and fast than WAN and all high resolution video can be saved totally without any loss. Someday, we do not need this kind of device when the public network become solid on bandwidth, however, it’s not now.

After I wrote the Vuzix Smart glasses for just hours, Google launched their glass and built a new web site for this product. Maybe google do not want to be left behind when Vuzix award from CES. http://www.google.com/glass/start/ The page is simple and clear. We could see a video in the link to sense how it feels. All the functions that describe in what it does are totally from audio, video and gesture recognition.

All of the recognition technology have to link with the requirements of people and that’s why google raise a competition for people to write down “what would you do if you had Glass”. Once the idea is adopted, we could become the Glass Explorer and buy Glass with USD $1500. ...
