My sense is that Hikvision’s wholly-owned lens manufacturer is using superior lens material as well as coatings that are optimised for low light, and possibly a simpler internal design to reduce attenuation of light passing through the lens to the sensor. The wide F1.2 aperture on a lens with a focal range of 6-136mm is going to be contributing to low light performance, too.

Importantly, a lens that works well in low light is not necessarily a great lens in backlight or in daylight but the Darkfighter PTZ, like its full body sibling, handles daytime as well as any other 1080p camera.

Something else Hikvision claims is that the new camera allowed license plates to be read at distances of hundreds of metres and yes, I can confirm this is true.
I saw the unit resolving license plates effortlessly at 200m and apparently the Hikvision Australia team expects performance to be at least 300m, which is really something. The company talks about getting colour(!) images down to 0.0005 lux, which is way less than the 0.002 lux of starlight. I didn’t see this sort of see-in-the-dark low light performance in our test though I can confirm the full body Darkfighter is very strong down to 5 lux in street surveillance applications, giving face recognition to about 5m at 7 lux. And with 200m IR capability, Darkfighter PTZ brings some big guns to the party. Important for a camera with designs on dominating external applications, Hikvision’s DarkFighter PTZ is protected by an IP66 rating against rain and dust, as well as being rated to IK10 against vandalism. This latter is rather unusual in top-line PTZ of this size. Often the thinking seems to be that these bigger PTZs will be pole or wall mounted well out of harm’s way and there’s truth in this.
But the fact Hikvision went ahead and fussed around with IK10 reflects well on the engineering team.Īccording to Tony Lagan of Hikvision Australia, performance of the Darkfighter PTZ is excellent and the new camera has blown away audiences at recent demonstrations in Queensland and New South Wales. “The Darkfighter PTZ has the full range of smart features – the IVA, intrusion detection, face recognition and smart tracking,” Lagan says. “There’s also line crossing detection and audio exception, as well as an IR distance of up to 200 metres, defog ability and electronic image stabilisation. “The sensor is bigger than half an inch, so it’s a huge sensor and I think that’s what gives this camera its low light ability,” Lagan explains.
