I am just back from a visit to the IFSEC in london and saw a cctv system called CCHDTV.
In a stand they showed 4 1080p camera's over one and the same RG59 wire (in a string). They used a camera with a module built in to simulate an televisionnetwork so every camera was an TV channel. The recorder then recorded every channel seperate. They said they also visit the ISC West in the USA but I can't find anything about them. I have there documentation but its strange that there is nothing to find about them in the media. Anybody ever heard about the system.
