Closed Circuit HD TV (ccHDtv) is a newly developed solution for transmitting full HD digital video in a surveillance system. The core concept of ccHDtv is to deliver high definition video using digital TV (DTV) transmission. With ccHDtv, high definition digital video can be transmitted easily over coaxial cables, twisted pairs, or simply over the air. Multiple 1080p30 and 1080p60 video streams can be easily transmitted using ccHDtv over a single 3C2V/RG59 cable up to a length of 500 meters without any repeater.</p> https://chenfu.ai/en/posts/pure-public-or-hybrid-cloud-for-surveillance/ Sat, 16 Feb 2013 00:00:00 +0000 https://chenfu.ai/en/posts/pure-public-or-hybrid-cloud-for-surveillance/ <p>The pure public cloud is no doubt that we build the web services on public and the hybrid combine the private part. According to the information on wiki, the public cloud aka external cloud is related to the service is provided by third party. There is a picture on wiki can describe exactly what we talk about.</p> <p>Basically, there are four deployment models on wiki. The private cloud can&rsquo;t satisfy the requirements of the surveillance system. We do not talk about the community cloud also because it&rsquo;s not real on surveillance system.</p>
