DYS30G619 is a professional zoom dual optical integrated system integrating a 30x optical zoom camera, 640 * 512 thermal imaging, and a high-precision 2- axis stabilized gimbal. The PTZ adopts high-precision encoder FOC control scheme, which has the characteristics of high stability, small volume, light weight and low power consumption; The visible light camera adopts a low illumination SENSOR with effective pixels of 2 million; The thermal imaging adopts 640*512 resolution vanadium oxide detector. The system supports RTSP output, picture in picture modes switching, multiple pseudo color display, and supports the global temperature measurement. Both the serial port and the network can control the camera and PTZ, and support local TF two-way video recording and photography. The thermal imaging lens of this model is 19mm focal length.
