Looking For Long-Range Camera Solution

I have a customer looking for a long-range camera to meet the following specs :

16.7-1000mm lens (60x optical zoom), 1080p resolution w/ starlight/lightfinder/equivalent and PT enclosure with wiper, heater and blower.

I had planned to use the VideoTec Ulisse Maxi with an Axis Q1635 and a Fujinon 16.7-1000mm lens, however I don't have enough space in the housing. Ulisse Maxi has 432mm space available, Axis Q1635 (136mm) + Fujinon lens (377mm) = 513m. Have had zero luck finding a suitable camera less than 136mm, or a suitable lens less than 377mm or a PT housing with wiper larger than 432mm.

Has anyone had any experience with long range cameras? Seems like this is a custom solution - the only thing I could find online was a website selling an analog solution with an Axis IP encoder for $65k USD. Any help would be appreciated.

Here's one to look at, it's discussed a little at the end of this thread.

I think that Ulisse enclosure is made from aluminum. I'd try contacting a higher-end auto body shop. You should be able to cut the enclosure and lengthen it in the middle by ~3.2 inches to gain the extra clearance.

You're right, what you're after isn't off-the-shelf, and is going to be costly. The added cost of the enclosure modification (cut, TIG, paint) shouldn't be more than $350-$500.

Your other potential option is to open up the Axis camera, and see if you can separate the sensor and lens mount from the body a bit, and flip the electronics around so they end up above/below the lens instead of directly behind it. That'll take a little bit of custom work, and will also depend on total clearance inside the enclosure.

@ C - I would prefer to not cut it open just in case that introduces water leaks in the future - I was able to check with the factory and it looks as if I'll gain a little bit of clearance at the back since the massive size of the lens means the camera will be lifted higher up and the back end will clear the PT motor and allow a bit more length. We'll see.

The suggestion by @A using a Cohu HD camera was really nice because they have a fully prepared package that meets all requirements. Am leaning towards a packaged solution instead of rolling the dice on having enough space inside a 3rd party enclosure. Also in my experience the minute you involve multiple vendors, each vendor's tech support blames the others culminating in a never-ending blame loop. Dealing with a single company is just so easy.
