Back to Color Security Cameras
Security Camera Resolution Security camera resolution is a measurement of the security cameras clarity. A security cameras resolution is determined by the number of horizontal video lines (like 400 or 430 lines) that the security camera needs in order to reproduce the desired image. The higher the resolution number, the sharper the image will be. Although resolution is important when considering which security camera to purchase, the quality of the security cameras components is much MORE important. We only sell high resolution, name brand, quality security cameras.
LUX How it affects picture quality
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 security 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!
