TH3020 employs 1/2.8 inch high quality CMOS sensor. Resolution is up to 1920x1080 with frame rate up to 60fps 20x optical zoom lens for options. The lens adopts 83.7° wide angle without distortion. Support low-power sleep/wake up, the consumption is lower than 400mW under sleep mode. Tele-education, Lecture Capture, Webcasting, Videoconferencing, Tele-training, Tele-medicine, Interrogation and Emergency command systems. Focus on intelligent image processing, to provide automatic white balance (AWB), automatic exposure (AE), automatic focusing (AF) function, fully automatically adapt to the environment, to achieve the best image effect, perfect trinity image automatic adjustment. Leading auto focus algorithm makes lens a fast, accurate and stable auto-focusing. Low Noise CMOS effectively ensure high SNR of camera video. Advanced 2D/3D noise reduction technology is also used to further reduce the noise, while ensuring image sharpness. Support VISCA, PELCO-D, PELCO-P protocols and automatic identification protocol. Support 255 preset positions (the remote controller is set to 10preset positions). Users can choose infrared remote controller or wireless remote controller according to the environmental conditions.2.4G wireless remote controller is not affected by the angle, distance or infrared interference.
