CCD (Charge Coupled Device) and CMOS (Complimentry Metal Oxide
Semiconductor) refer to the image sensor in the camera. Cameras that use
a CCD as the image sensor produce a better image than ones that use a
CMOS sensor, particularly in low light, but they are more expensive. An
article on them can be found here:
http://electronics.howstuffworks.com/question362.htm
This article is about digital cameras, but the info is still relevant to
'webcams'. Technical details on the difference between the two devices
can be found at the links at the bottom of the page.
Possibly the 'cheapest' CCD camera is the Logitech Pro 4000, but it is
not a network camera.
Probably the 'best known' CCD network cameras are Axis and Mobotix, with
Mobotix being the better of the two (in image quality), but both brands
are very expensive. Maybe do a search for either 'Network cameras', 'IP
cameras' or 'CCD cameras'
There are some good quality CCD network cameras around that won't 'break
the bank' (Axis and Mobotix would break mine!!!...especially because of
the prices they want for them here in Australia)
An example of the quality of them can be found here:
Axis:

Mobotix: http://194.129.55.90/
Basically it it depends on how much you want to spend and what you are
using it for. Personally, I would be happy with images of the quality
that Graham is getting. It is also a question of finding a 'balance'
between image quality, purpose of use and price!
Technically, there should NOT be any difference between the quality of
wireless or LAN images from the same camera.
Sorry if all this has only confused you
