1·1/3” SONY CCD
High definition infrared color camera
2. Use 12 imported IR LED lights to project light sources at different angles to make the image clearer
3. Infrared automatically turns on when the light is below 10Lux; shooting distance is more than 15 meters
4·Imported lens lens, waterproof gas affects image
5·Flat wall installation / corner 90 degree installation two appearances
Infrared camera technology is divided into passive infrared camera technology and active infrared camera technology. Passive infrared camera technology uses the principle that any object emits infrared light above absolute zero (-273 °C). Since the infrared light emitted by the human body and the hot object is strong, the red light emitted by other non-heating objects is very weak, so nighttime monitoring can be realized by using a special infrared camera. Passive infrared camera technology is not used in night vision systems because it is expensive and does not reflect the surrounding environment. Active infrared camera technology uses a special "infrared light" to artificially generate infrared radiation, which produces infrared light that can be invisible to the human eye and can be captured by ordinary cameras. It radiates "lighting" scenery and environment, using ordinary low-light CCD black-and-white cameras or using "daytime" Color nighttime automatic black and white "camera or "infrared low-light color camera" to feel the surrounding environment
Infrared light reflected back to achieve night vision.
Light is an electromagnetic wave whose wavelength range is from a few nanometers (1 nm = 10-9 m) to about 1 mm (mm). The human eye only sees part of it. We call it visible light. The wavelength of visible light ranges from 380nm to 780nm. The wavelength of visible light is divided into red, orange, yellow, green, cyan, blue and violet, and the wavelength is shorter than violet. It is called ultraviolet light, and the wavelength is longer than infrared light, called infrared light.
