Axis’s Lightfinder technology is an in-house system-on-chip tech that carries extreme light sensitivity. It’s used for day-and-night cameras, kicking into gear whenever light is dim or quickly lowering. Basically, this technology is an exemplary version of the low lux technology found in most cameras. Lux is a measure of lamination and when cameras speak of lux they’re referring to the lowest illumination possible at which it can maintain a visible image. It’s hard to say what, exactly, gives Axis the edge here. It’s little surprise the manufacturer is hesitant to reveal all that it has. As a user, the utility of Lightfinder becomes immediately obvious the second one runs into a low light scenario.
Lightfinder incorporates a CMOS sensor with light sensitivity beyond ordinary sensors. Of course, the sensor itself is not pulling all the weight. Axis’s software developers have maximized performance as well. What we have here is a front-end sensor pulling a lot of weight by itself, and the back-end software squeezing out whatever’s left, giving super crisp images in lowly lit lighting conditions.
Given that the cameras which use Lightfinder are digital, you can band the technology up with other advances such as video intelligence analysis and video surveillance systems. From our experience, cameras that are equipped with Axis’s Lightfinder produce very sharp images. It’s a combination of night-vision, Lightfinder, WDR, and noise reduction. If a camera has all three, it’s extremely well suited to virtually any lighting condition, day or night.
