The long range ptz thermal camera are usually for defense and surveillance applications. Conventional thermal imagers used for monitoring generally have a resolution of 384×288, 640×512. With the development of technology and increasing monitoring requirements, high-definition thermal imagers with a resolution of 1024×768 have come out. High-quality picture quality and stable performance are gradually being applied to the border and coastal defense industries. Shenrong, after unremitting technical research, has developed its own movement, which greatly reduces the cost of thermal imaging cameras while maintaining fine images, which has had a huge impact on the entire industry.
