The spec sheets themselves note that the camera can do color with 0.009 lux minimum illumination. Most of Dahua's other Starlight entries claim around. 0.005 lux minimum illumination, which makes this one of their weaker entries in the field for what they consider Starlight... Strange entry in the field, especially since this only available for the branded product line in the USA.
It seems forced since all the other Starlight products are still 2-3MP. The jump to 5MP feels like they are overclocking the chip and throwing caution to the wind to pose an answer to other "Starlight" products out there that are falsely claiming the title with 0.01 lux minimum illumination for color images.
Still, this is weird. Very, very weird. It seems like a hastily thrown together beta.
What chipset firmware was it using? Rhea? Eos? Nova (not likely)? It'll give some insight as to how they threw this one together.
Dahua tends to have three tiers for their cameras. This seems to fall into the mid-tier. Top tier includes more advanced features like audio in/out, alarm in/out, larger chasis, and better IR. Trying to discern thier product design is like betting on the horses — it’s just a big guess. This does appear to be an in-between camera tier. Let’s see what the next 5mp starlight offering is with a larger dome and better features.
