Camera Lense Capture Size

Hello Guys,

for a tracking system (ceiling -> floor) I would like to use the Unibrain Fire-I board-camera with a 12mm Telephoto Lens:…-e-i-BC.htm…-pf-id=2041

The distance of the camera is ca. 480cm and it should also capture the width of ca. 500cm, I figured that this would work with that lens.

Does anybody have some experience with this to comment on that, and maybe what else is to take care of?

Great thanks!
