An auto-iris lens automatically adjusts the iris (or aperture) in order to regulate and optimize the amount of light or infrared energy a camera receives. This is ideal for outdoor video surveillance cameras, as they often have to deal with changing light conditions and high-contrast situations. The iris is not a digital image process but is a physical opening built into a lens that is controlled by a small servo motor and is frequently used in tandem with DSP image processing such as WDR; HLC and BLC. It allows security and surveillance cameras to adjust and optimize the image on the fly based on the changing light conditions.
A varifocal lens is a camera lens with variable focal length in which focus changes as focal length (and magnification) changes, as compared to a par focal (“true”) zoom lens; which remains in focus as the lens zooms (focal length and magnification change).
The TV2712D-MPIR from Hikvision is a Varifocal Auto Iris DC Drive 3MP IR Aspherical Lens.
