Please recommend cctv dome camera

["wdoe999@xxxxxxxxx" <wdoe999@xxxxxxxxx>]

Hi - I have a small security camera system.  I have purchased several
cameras from ebay.  Usually some cameras around 70 bucks.  I'm not too
crazy about the image quality.  Can someone give some tips on what to
get, and how much I have to spend to get that next step in quality.

The claims for the cameras that I have already purchased are:
Vandal proof dome (it's just a metal housing)
1/3 Sony CCD
480 lines
3.6mm or 4mm lens
IR LEDs (I don't really need this)
Priced around $70

You definitely cannot read a licence plate with these cameras and
you'd be hard pressed to ID a face.
I've purchased box cameras with CS lenses (with the same price and
specs and 4mm lens) and they seem to have a better picture (I'd
estimate 30% better).


So any recommendations for a dome camera that would have the same
image quality of the box cameras?  And how much does it cost to go to
the next step (and is there even a next step or is that as good as it
gets for small cameras).

Thanks
