A member wants to see farther than what speeddomes offer. Even high end speeddomes (30x, 36x, 40x, etc.) generally have no more than 100 - 150mm max focal length ranges. (Background: How Far Can a PTZ See?)
Let's put together a list of products that offer this. I'll start with one.
The Cohu 8800 has a max focal length of 2000mm, with a 60x zoom from 16.7mm to 2000mm.
That's dramatically longer range than a speedome but has a much narrower wide angle (20 to 27 degrees versus 60+ degrees common for speeddomes).
What else would you recommend?
