The camera provides a specially designed ring structure to prevent blurred pictures and diffused reflection from particles on glass (patent pending). The 1/4" Sony super HAD CCD delivers clear color pictures during the day and automatically changes to black-white at night. It has a removable IR cut filter (day: one lux, night: zero lux), optical 26X zoom (optical 26X, digital 10X), auto focus, auto iris and 180 built-in IR LEDs for more effective illumination. The camera features a separate control board for infrared LEDs, prolonging their life span. It illuminates only when dark thanks to the built-in CDS sensor. In addition, the optimum circuit-board design lowers heat from infrared LEDs. Moreover, it is equipped with a vandalproof case with polycarbonate front glass. The weatherproof housing contains a built-in cooling fan and heater (KIR-100ZAH) or just the fan (KIR-100ZA).
