Idea! Cam sample picture database

After looking at alot of ebay CCTV cameras, its impossible to find out the quality of the camera unless you purchase it & see for yourself.
Wouldn't be a good idea if someone setup a website with a database of cameras & their sample pictures?

If we were to do some kind of database of camera quality, we'd have to have a standard...
Here's an idea: A standard printout placed 50 ft away from the camera... Camera _not_ zoomed in, quality setting set to the highest possible for the camera, but at a default resolution (640x480?). The reference printout would have text of various sizes, and a graphic... and the images would be show as a reference, but not rated... the end user would make their own decision on the quality of the image.
Good idea? Bad? How would we create the image? Can we create an image that tends to have artifacts (As this would test the camera jpeg images the best)?

Has anyone thought of looking at and reading the specs for the cameras?

The Specs of a camera do not guarantee picture quality. And similarly specced cameras may have vastly different end results... the idea here is maybe we can create a database of which one could reference off of.
This might be a lot of work, but if everybody took one picture with some kind of reference image with a standard setup with their different cameras, someone could decide if a more less expensive brand would be good enough for my application vs. a more expensive brand.
They say that a picture is worth a thousand words... Comparing two pictures from different cameras says alot about those two cameras.

The problem is you would have establish a reference (a test plaque, similar lighting, etc.). Without that, the pictures could be misleading. If one person was to manage it it could be possible but for a community would be difficult. The thing to pay attention to is the lux rating and the Horizontal lines (for CCTV anyway) or the resolution (for a IP cam), if it has auto iris (or can be upgaded to auto iris for views out doors), etc.
