IR-EO Cameras & Systems Co., Ltd. is one of the most reliable manufacturers and suppliers of photoelectric turret for maritime rescue in China. Our factory offers high quality products made in China with competitive price. Welcome to contact us for customized service.
Features
This product is a photoelectric turret that integrates observation capabilities and acquisition of target feature measurement data. The product has the ability to stabilize the visual axis. And it is equipped with LWIR thermal cameras, MWIR thermal cameras, and visible light televisions. The LWIR thermal camera and the MWIR thermal camera simultaneously output an original 16-bit characteristic measurement video (the video contains calibration parameters that can be used for characteristic measurement calculation) and an 8-bit video for observation.
Function
System Features
The product has the function of collecting characteristic data of targets on ships, sea surfaces, islands, and reefs, and has search, identification, tracking, and other targeting functions.
The details are as follows:
1) With search functions of manual sweep, automatic fan sweep and automatic weekly sweep;
2) With designated tracking function;
3) With functions of collecting thermal imaging datas LWIR, MWIR from the target;
4) With azimuth target and itch angle output functions;
5) Ability to report data such as current line-of-sight position and angular velocity of line-of-sight movement;
6) Equipped with the function of calibrating the visual axis of TV and thermal images;
7) With digital video image freeze function;
8) With automatic equipment monitoring and fault location functions.
LWIR Thermal Camera Function
1) The brightness can be adjusted manually and automatically;
2) Contrast adjustment can be done manually and automatically;
3) The cross grid can be shown/deleted/moved, and the moved cross grid can be saved in the moved position after saving;
4) Equipped with non-uniformity correction function;
5) The integration time can be changed between preset gears, and at least 4 gears of integration time can be preset;
6) It can output original 16-bit video and 8-bit Cameralink video (two Cameralink outputs at the same time). The original 16-bit output video data has a fixed circuit gain;
7) It can output the temperature of the lens (part of the front lens, part of the rear lens) and the temperature of the detector;
8) Video status information, including integration time, frame rate, etc., can be generated through images.
