Specialist COVID-19 fighting technology. Beyond Security
With advanced detectors and algorithms, Hikvision’s Temperature Screening Thermographic Cameras are designed to detect elevated skin-surface temperatures, and can thus be used for rapid and preliminary temperature screening in office buildings, factories, stations, airports and other public places, with accuracy up to ±0.3°C.
- One second to detect skin-surface temperature of a person
- Multi-person detection simultaneously
- Non-contact measurement to avoid physical contact
- Immediately alarming to notify operators
- AI detection to reduce false alarms from other heat sources
WHAT’S THERMAL IMAGING TECHNOLOGY
The spectrum of visible light is actually only a small part of a large band of detectable signals, or waves, that travel through matter. The electromagnetic spectrum contains radiation from various invisible wave types, each with a unique wavelength. Thermal radiation is one of these, featuring longer wavelengths than those of visible light, and is therefore generally invisible to the human eye.
Any object with a temperature above absolute zero emits a detectable amount of radiations. The higher an object’s temperature, the more radiations are is emitted. Taking advantage of the temperature differences between objects, thermal cameras make the invisible thermal radiation “visible” in the form of heat zone images.
