Digital transmission will soon reign in all facets of video. In fact, Congress has mandated that, after February 17, 2009, full-power television stations will stop broadcasting in analog, and will continue broadcasting in digital only. Digital is a more efficient transmission technology that allows broadcast stations to offer improved picture and sound quality, as well as offer more programming options for consumers through multiple broadcast streams (multicasting). While this movement is affecting CATV, CCTV is also running a parallel course. Digital IP cameras for security is the fastest growing trend because of its ability to connect to cameras to the network for instant viewing through Ethernet. Digital security cameras will have the best resolution as megapixel technology evolves.
However, it is not only the cameras and the receiving equipment that create quality pictures, cable selection is a key variant, too. Going from a previous coaxbased world to UTP and/or fiber for digital transmission, brings a new set of parameters. The old adage of “Just slap a BNC connector on the ends of a coax cable and connect the camera and it will work fine,” will not hold true. Cable is no longer a commodity when it comes to digital video transmission. And if you think cable does not make a difference, just bend the cable in your own home and see what happens to the picture on your TV.
