Conax has chosen the three largest CAM manufacturers using advanced security to supply CI and CI+ CAMs to our customers. Customers can choose between any of the three manufacturers, and purchase the CAMs directly from Conax. Conax evaluates and grades the CAM to ensure operability and quality. This ensures the security of the product and the integration to the head-end system. There is also a wide array of packaging options that customers can choose from. A CAM is often used as a STB replacement, and is typically used for the second TV, as it is very economic voltage vise, and requires no additional antennas. The CAM is unique in other areas, as there are no cables or remote control.
