The utility model relates to equipment arrangement of frontier ports, in particular to an infrared thermal imaging body temperature video monitoring system which comprises a monitor and an infrared detection head installed together with the monitor. The monitor is connected with a video display through a wireless communication module, a focusing zoom assembly is arranged inside a monitor machine case, and the infrared detection head is arranged on the focusing zoon assembly. A signal processor of the infrared thermal imaging body temperature video monitoring system sends converted standard infrared image information to a cloud computation application service platform through the wireless communication module and receives auxiliary decision information obtained after an expert database system of the cloud computation application service platform analyzes and processes the image information. A user can objectively know the existing state of an object according to the information, accuracy is high, and scientificity is good.
