This 3.5-8mm varifocal CS-mount lens for CCTV cameras makes a great replacement or upgrade for a damaged, vandalized or broken varifocal
CS-mount lens. Is has an auto-iris for dynamic exposure control
based on available light.
Designed for Board Cameras
This lens is designed for board cameras (it is not a C- or
CS-mount style lens).
Since it uses an auto-iris to control lens aperture, it works
best with a board camera that auto-iris control circuits (there
is no way to adjust the lens' iris without auto-iris control).
