The term used to identify the light sensitivity of CCTV cameras is?

The term used to identify the light sensitivity of CCTV cameras is "Lux." Lux is a measurement of illumination that quantifies how much light is available in a given area, specifically in relation to how sensitive a camera is to that light. In the context of CCTV systems, lux indicates the minimum amount of light required for a camera to produce a clear, usable image. A camera with a lower lux rating can operate effectively in lower light conditions, making it suitable for nighttime surveillance or poorly lit environments.

Understanding lux is essential for choosing the right CCTV camera for specific lighting conditions. A camera that performs well in low lux situations is indispensable for security applications where visibility is crucial. The other terms, while related to light and visibility, do not specifically refer to the light sensitivity of cameras in the same way lux does.
