However, the 6026 outperformed other cameras tested, even with the higher F number lens. Performance was moderately better using Hikvision's F0.95 lens compared to the stock F1.5 model included with the camera. However, in dark scenes at longer ranges (~100' distance/150' HFOV), the DarkFighter model easily outperformed the integrated IR camera, since illumination provided was weak at this range. Integrated IR still provided moderately better images, especially in very low light scenes (~0.01 and below) and at shorter range. Here is an example that show the difference (field dark scene, 100' away / 150' wide FoV): In our tests, the Hikvision 6026 DarkFighter's low light performance was the best of all 'super low light' cameras tested by a material margin. We performed testing in multiple low light scenes like the nighttime dark field with a subject 100' away, excerpted here: To see how they compare, we bought their 1080p box DarkFighter model, the DS-2CD6026FHWD-A, and put it up against leading low light models from Axis, Samsung, and Uniview, as well as their own 4132 integrated IR camera. F/0.95 HD lens (instead of the F/1.2, F/1.3 or higher common with HD).The big two differences Hikvision is offering: Hikvision's new offering, 'Darkfighter' targets that market. In particular, Axis started the 'super low light' trend a few years ago with their 'Lightfinder' offerings. However, most do not consider Hikvision to be in the same league for high-end cameras such as Axis and Samsung. The Chinese mega-manufacturer has made a name for itself as a low-cost leader, popularizing $100 HD cameras with integrated IR. Can Hikvision beat Axis and Samsung in pure low light?
