Constant temperature of infrared hemispherical camera

Due to the configuration of high heat value of the infrared lamp, after the infrared lamp is started, there will be heat concentration at the front end of the infrared hemispherical camera during the whole working period (calculated by 12 hours), that is, the temperature at the front end of the cavity is high, and if it cannot be evenly radiated, it will affect the normal work of other components such as the camera. China-Shandong Communication Company has solved this problem well by designing and using automatic heating and cooling air conditioners with forced heat dissipation and forced cooling.

The automatic heating and cooling air conditioner adopts the Peltier effect principle, which can automatically adjust the temperature control circuit to keep the temperature in the protective cover within the normal working temperature range of the camera. When leaving the factory, the temperature in the protective cover is set below +5℃ when heating and above +40℃ when cooling. Experiments show that the infrared camera can work normally in the outdoor natural environment of -40℃ ~+70℃ (direct sunlight).
