So I spent a lot of time going through all the HikVision and Dahua cams. I was looking for cams with 1/1.8" sensors, WDR, 2.8mm and turret or bullet at a price of <$300. All the Hikvision cams that met the technical criteria were $800-$1300 so they were out. At the end I boiled it down to two Dahua cams, i.e.
A82AG52, 4k@15fps, 2.8mm, 1/1.8", starlight, true WDR, 120dB, 12VDC, F1.6 (the spec sheet didn't say if it's PoE which is what I need)
N45DJ62, 4MP, 2.8mm, 1/1.8", starlight+, 140dB, ePoE
The N versions seems to be more expensive (close to $300) compared to the A versions. What does N and A mean and is it worth the cost difference? The A version above is 4k but the dB numbers are 20dB lower which is pretty significant. Also what is the difference between the starlight and starelight+ (and starelight advanced)?
