Smart IR, no IR-saturation effect

For testing its day/nigth surveillance performance, we put this PTZ camera into dark room, we will adjust the brightness of light for testing its images under different illumination environment. When it's in 10.66Lux, slight noises are emerged from images, but overall images keep clean and crisp, white balance is accurate. Continuing decrease the brightness, when illuminometer indicates 7.34Lux, the camera automatically switch to B/W (night) mode.

B/W mode under 4.21Lux

Additionally, we also tested the smart IR function. When testers constantly approaching to camera from a distance, the dome camera will adjust the brightness of the illuminators, therefore to avoid IR-saturation. At B/W mode, the tester's facial details are clearly identified, the quality of image is excellent. Coordinating with pan/title/zoom features, the camera can adjust its IR level for different distance and zoom times. During the testing procedures, day or night, the camera can provide accurate PTZ rotation features and no preset offset phenomenon, PTZ performance is quite good.
