Looking for a USB camera with small field of view / high zoom
I'm looking for a camera for computer vision that has a FOV of about 11°. To facilitate the design, it would be great if it could connect directly via USB to a computer running ROS.
However all the webcams I'm looking at have a FOV of 70°-120° and all the more advanced cameras either only have analog live output or firewire. I would like to avoid Firewire, since almost no small PC still suppports it.
Does anybody know of a usb camera with a small fov, exchangeable optics or hardware zoom?
