One side of the heat-transfer sheet is tightly connected with the body of the camera and the other side thereof is tightly connected with the low-temperature side of the semiconductor refrigeration sheet. The radiation fin and the fan are arranged on the high-temperature side of the semiconductor refrigeration sheet. The refrigeration system is arranged in any position of the upper part, the lower part, the left part or the right part of the camera. In order to protect the camera against the effect of the refrigeration system, a temperature control switch is arranged on the circuit of the refrigeration system. In order to ensure that the camera works normally under the condition of low illumination or zero illumination, the camera further comprises an auxiliary light source such as an LED lamp, a flash lamp or an infrared emitting lamp. The high temperature-resistant camera can work normally in harsh environment with high temperature and high humidity. Compared with the prior art, the high temperature-resistant camera has the advantages of small overall size, simple fabrication, simple field installation and high performance-to-price ratio.
