These manual iris lenses are ideal for fitting to analogue traditional style CCTV cameras.

Suitable for most indoor applications as the amount of light entering the camera can be manually adjusted using the lens iris ring. If the light level is too bright, the iris can be closed slightly, if too low, it can be opened.

As this adjustment is manual and not automatic, this lens type is not recommended for external applications where the light level varies greatly from day to night time.
