Compared with Wuhan AutoNavi Infrared and Huagong Technology, Wuhan AutoNavi Infrared is better. Wuhan Gaode Infrared and Huagong Technology are two well-known domestic thermal imaging equipment manufacturers. Wuhan Gaode Infrared has mature technical strength and multiple patented technical support. The thermal imaging equipment it produces has excellent performance, high precision and high resolution. High efficiency, high sensitivity and other characteristics; while Huagong Technology's technology research and development is relatively weak, and there is still a certain gap with the industry's leading level, so Wuhan AutoNavi Infrared and Huagong Technology are better than Wuhan AutoNavi Infrared.
