have you ever heard of RICOM a mdel of high resousion lens from RICOM EV0922DB.HR 9-22mm board mount 1/2inch

hwo about purchasing cctv lens separately?

i'm wondering the shutter speed of auto aperture depends on how the DC driver works,for the advantage,comparing to manual iris,it could be more convenient and just two status,close or open,but once you installed the camera with manual iris at a hard-touched position,it seems simlilar to auto iris given the stable light.

focal length:3.5-9mm IR format:1/3 board mount aperture:F1.2 aspherical lens this is a special lens with IR function

awesome spherical lens are easier to get into this problem. btw provided somebody wanna set up the surbeillance system for a region as wide as the football field,what kind of lens should be installed?

have you met with the problem of dark corner frequently appearing in the screen.
