Since I sell security cameras for a living, I can tell u that this camera will be one of two basic colour camera models.
Its either a HD 3mm lense/internet camera (yes, very basic colour web cam) or it will be a security style 1/3inch 3mm colour camera which will be rated around 450TVL. (450TVL means its not entry level, but close to it).
Since they had it hooked up to a 42 inch TV, it could have been a webcam hooked up to a computer, than a output running to a TV, or just a Security Camera hooked up to a Digital Video Recorder that again had outputs to a TV. All very easy to do.
The cost for something like this is less than $100 in my industry.
