I did reply to this yesterday, but you deleted the thread so I scrapped it!
Anyway, I was going to point out that when I looked a few years back, most camcorders didn't have video in, or it was disabled to avoid the duty applied to VCR's, which was higher at the time. I expect even if one does have it disabled then it could be re-enabled without too much trouble.
Also I have found
www.henrys.co.uk to have a good choice. I believe the Exwave Super HAD cameras are best, but I don't know if they are available in bullet form. You might find that for a little more money you could get a normal CCTV camera and ruggedise that a bit.
