    Would anyone be able to easily explain "LOR" better know as Light Output Ratio (I think:confused:). I'm trying to understand the difference between different CCTV cameras, decribed as having 350 LOR, 550 LOR, 420 LOR ...etc. Searchs in google return very complex explanations, which have made little to no sense.

    The following link is where I have been looking at buying a camera. They don't seem to explain what "LOR" is, and all their cameras seem to be advertised with the ratio. http://www[dot]scdlink[dot]com

    I'm guessing that the higher the "LOR" - the better the image in low light. In a low light condition, such as at night, would a camera with a high LOR be able to display an image without any IR leds?

    Any thoughts or insight?

    I think LOR refers to "Lines of Resolution" not Light Output Ratio in this case

    Well now I feel dumb! Thank you nanovate - that makes much more sense.

    I guess I caught up with the idea I was looking for something to see in the dark.

    Thanks again!
