What does “lux” mean?
Lux (1/10 of a foot candle) is a standardized method by which to measure a security camera’s sensitivity to light. The lower the number, the less light it will take to reproduce a clear image. For example: A securtiy camera that sees down to 1 LUX, means it generally has the ability to see an image during early evening hours or just before dusk. A security camera that’s down to .1 has the ability to see an image in let’s say, a well lit parking lot. A rating of .05, the ability to clearly view an image in a dimly lit area at night. A .05 image can usually enable a security camera to actually see better than the human eye at night!
• “Lux” is a technical term used throughout the lighting industry and is used to measure the amount of light energy in lumens falling on 1sq.m. A “Lumen” is a unit for luminous flux (the flow rate of visible light energy) and is also used to measure light. Typically in a home, you need approximately 250 lux and in an Office or Classroom, you need approximately 450 lux.
