Pelco’s Spectra® Pro IR Series can see in absolute darkness. The infrared illumination (IR) has proportional brightness based upon zoom, creating visible pictures without any light up to 150m from the camera. The IR wavelength is 850nm giving an almost undetectable light source in locations where visible light is undesired or light pollution is regulated. The Pro IR Series offers a wider tilt range giving the camera the ability to look above the horizon 15° (center of field of view).
