A low-light camera is a surveillance camera that still captures sharp images at lower illuminance. Most cameras are mostly at 0Lux or 0.1Lux.
Illuminance, or light intensity, is a physical term that refers to the energy of visible light per unit area. Unit: Lux Lux, Jane Lx. The illumination mentioned by the security industry is indicated by Lux.
0Lux means that it can be shot without light. Generally, most cameras are at 0Lux or 0.1Lux. The illuminance value depends on the aperture size (F value) of the lens. The smaller the F value, the lower the illuminance required.
From color cameras from 0.0004 LUX to 1 LUX, black and white cameras from 0.0003 to 0.1 LUX (or 0 LUX with infrared). The industry believes that the illuminance can be as low as not only depending on the aperture size (F value) of the lens, but also under what conditions can the LUX value be indicated. Otherwise, it will have no practical significance if it flows on the digital surface. . In terms of aperture size (F value), the larger the aperture, the smaller the F value it represents and the lower the required illumination.
Low illumination camera minimum illumination level:
0.1Lux: dark level
0.01Lux: Moonlight level
0.001Lux and below: Starlight
A CCTV camera that can work under extremely faint light. A closed circuit television system that can operate in low light conditions with normal visual response.
Illuminance is expressed in Lux. 0Lux means that it can be shot without light. Generally, the camera is mostly at 0Lux or 0.1Lux. The value of the illuminance depends on the aperture size of the lens (F value: F is the ratio of the focal length of the lens to the diameter of the aperture. The smaller the ratio, It means that the larger the aperture, the larger the amount of light passing through), the lower the illuminance required for the smaller the F value.
Cameras range from 0.001Lux to 1Lux. There are many different opinions. When the Lux value is 0.001, the star-level illumination is basically reached.
As the name implies, a low-light camera is a camera that can still capture clear images under low illumination conditions. There is no uniform standard for the technical specifications of the CCTV industry. Therefore, it cannot be defined as the minimum illumination. The value can be called low illumination. Camera. Moreover, the value of the minimum illuminance is related to the aperture size (F value), electronic sensitivity (ELECTRONIC, SENSITIVITY), and infrared switch state of the lens. Therefore, it is necessary to examine the minimum illuminance of the camera under the same test conditions.
