Closed circuit television or CCTV is the industries standard in surveillance cameras. CCTV is often a single network of cameras, multiple networks of cameras linked together via switches or the internet, or wide area computer technology. In the instance of using CCTV online, the video is digital and therefore possible to be managed and stored automatically by computers and network storage devices. This technique is often used in areas that require constant monitoring such as banks, casinos, airports, military installations and convenience stores.Another meaning CCTV takes on is the China Central Television. This network provides news and information to the majority of China, and is currently broadcasting the Olympics that are being held Beijing. When you Google CCTV more search results come up for the Olympics rather than closed circuit television because it is much more popular and relevant to what is going on in the community.
When the Olympics are over and much of the hype dies down, the closed circuit television (CCTV) will come back up as number one in Google searches. Google always shows the most recent and up to date news first, even if what you are looking for is a more popular search term. In this case, the Chinese Central Television holds more weight in Google due to its relevancy to the Olympics.

Good point. I see this issue with a lot of surveillance terms. For instance, dvrs and nvrs return results for home entertainment, equipment, video analytics is increasingly being associated with entertainment and online uses, etc. Even when you search for cameras (e.g. pelco, axis), you generally get dozens of people selling them rather than writing about them.
I recently launched a search engine just for video surveillance - http://ipvideomarket.info/search. I think this could help some people get only surveillance related results. It's only been up a week but already over 100 searches are being done per day.
