The Nuoptic VIS-1040 Series 40W Covert Varifocal IR Illuminator is used with both analog and IP day/night video security cameras. A varifocal illuminator with a maximum illumination distance of up to 359' (109m), features 940nm high-efficiency LEDs and uses precision optics, enabling you to set to any value between 9 and 95°, without having to change a single part.
With up to 64 presets for integration with PTZ applications, this illuminator can store illumination and brightness levels that match the camera’s field of view. In addition, its field of illumination can be set to match the setting of the camera lens. It can do both wide and narrow settings with the VIS illumination technology, thereby eliminating the need for two separate illuminators.
Installation is facilitated by control knobs located inside the unit’s environmental cover or by using the RS-232, RS-485, or Pelco D interfaces.
