What is a CAM?
Top Up TV CAMCAM stands for Conditional Access Module. Some set-top boxes have a CAM slot, which means that you can plug a CAM adapter into this slot, and plug a TopUp TV subscription card into the CAM adapter slot.
At the time of writing, using a CAM means that users of a NetGem I-player (not the BT version), the Nokia 221T, as well as certain models of iDTV (integrated digital TV sets), can make use of a CAM to get Top Up TV.
The CAM adapters cost around £40-£50, and are in addition to the cost of a set-top box and a Top Up TV subscription. To order a CAM, go to Currys , BT Shop, Empire Direct or try Ebay.co.uk.
Latest: Currys are selling a CAM plus TopUp TV card in one package for under £50 , which may save you money
