I've used allot of hikvision cameras on various installs and I like them but I have the need for some higher zoom cameras but have a hard time finding anything reasonable that has more then a 8mm lens. The cheaper cameras like the 2CD2085 / 2CD2385 or the less MP versions of those come up to 12mm but even those are hard to find in the US. In this case I really need something more like 24mm+. A couple years ago I seen a site that was selling a lens you could swap into the turret I think that converted a 8/12mm into a 24mm or so but I can no longer find it. What fixed lens higher zoom cameras are out there that are not $500?
