What is a CAM or conditional access module? (aka card slot)

CAM stands for Conditional Access Module. It is a device into which you can slot a smart card that allows you to view encrypted channels.

Some digital boxes & TVs have a socket where you can plug in a CAM if you want to watch channels whose transmissions are encrypted.

As it is only pay per view channels that are encrypted you do not require a CAM to receive Freeview. Freeview does not have any pay per view channels - all Freeview channels are free to view.
