Hmm I'm not sure about that, was thinking the same thing, will the 4MP version of this G2 ColorVu produce even brighter picture then this 4k 8MP one? When the sensor size is the same, yes, but I just had a look at the specs on their website:
| DS-2CD2087G2-L(U)
4 K ColorVu Fixed Bullet Network Camera | DS-2CD2047G2-L(U)
4 MP ColorVu Fixed Bullet Network Camera |
Image sensor | 1/1.2″ Progressive Scan CMOS | 1/1.8" Progressive Scan CMOS |
Minimum illumination | 0.0005 Lux @ (F1.0, AGC ON), 0 Lux with Light | 0.0005 Lux @ (F1.0, AGC ON), 0 Lux with Light |
So.... the 8MP has a much larger sensor then the 4MP version, resulting in the same amount of minimum illumination and thus the same low light performance?
