The calibrator is a part of project-based approach of Hikvision.It means that the wholesale price of the camera depends on the characteristics of the proposed project and is subject to negotiation.
The DS-2TE127-G4A is a device for precise calibration of Hikvision thermographic cameras dedicated for precise temperature measurements. The calibrator imitates a perfectly black body (absorbing all thermal radiation from the environment) and emits heat with a constant, unchanged temperature. When used, the module ensures very high measuring accuracy with only +/- 0.3°C error. The module is controlled by an interface with an LCD display.
Principle of operation and advantages of thermal imaging
A thermal imaging camera is a perfect complement to visual monitoring in the reflected visible light and near-infrared radiation. Analog or IP cameras used in video monitoring enable correct identification and recognition of people during the day and at night with the use of infrared illuminators. A thermal imaging camera does not need any lighting for proper operation. Its operating principle is completely different than in the case of traditional cameras. Any body with a temperature above absolute zero (0 K = -273.15°C) emits infrared radiation. Due to the existing relationship between the temperature and radiation intensity, a thermal imaging camera, receiving the far-infrared radiation, calculates temperature values based on the wavelengths of the radiation. So, a thermal imaging camera can show the temperature distribution on the surface of the examined body and measure the temperature values.
