*Only a recomendation to investigate
These guys 2BSecurity, look like maybe they're OEM'ing some motorized fuji lens with somebody else's PTZ control. Still, an effective focal length of 2000m makes it worth mentioning.

Who makes super long motorized zoom lenses? Kowa, Pentax, Fujinon, Computar... anyone else?
As an engineer who has custom-integrated similar very-long-range camera systems, the detailed specifications of the Cohu look very impressive to me. The support for VMS interoperability via ONVIF is key, assuming that the specs are accurate. It's one thing for a vendor to put together different components (heavy duty high-accuracy PTZ, pressurized enclosure, big zoom lens, IP camera) but another thing to integrate them all under a single standards-based interoperable network API that actually works. Doing this custom cost tens of thousands of dollars in components, and was usually integrated into fully custom recording systems. Getting the cost of the hardware as well as the integration effort down will be very helpful for border and port security applications.
I would encourage integrators to test a demo unit of such a device with their desired VMS before committing to such a project. Besides just control protocol interoperability, subtle things such as the minimum pan and tilt speed of the VMS user interface can make or break the usability of extreme zoom systems.
Videotec does offer Pan&Tilt unit for application for large lenses. Videotec's ULISSE MAXI is not typically equipped with camera/lens combo but it offers the capability to take some of the largest lenses on the market.
This is typically offered in two flavours:
- Analogue set-up ULISSE MAXI. Several application with large motorized zoom lenses. Some customers even used with Fujinon 60x.
- IP set-up ULISSE MAXI NETCAM. For Network Megapixel cameras compatible with ONVIF protocol, Profile S. Tested with some 33x (15.2 - 500.0 mm) megapixel lenses. VMS (ONVIF protocol, Profile S compliant) will see the combo as a single IP address. It will still possible to tunnel and access original web-browser interface of the installed camera.
