I've been looking at the other EXMOR R options and in the ultra-smart range and I noticed the
IPC-HDBW8231E-Zdome, which is very similar apart from having 140db dynamic range and a marginally better (0.005Lux) min illumination. What confused me was there's also an ultra-smart 3MP dome
IPC-HDBW8331E-Z which appears to be otherwise identical to the 2MP dome, suggesting you can add 50% more pixels with no trade-offs, which doesn't seem right and would suggest it's an even better sensor?
It's twice the price compared to this IPC-HDW5231R-Z, so not as good bang-for-buck, and it's a shame they don't make it in a turret version, but I'd be interested to hear your thoughts anyway on how much you gain by going from 2MP 120db 0.006Lux to 3MP 140db 0.005Lux. Assuming they're both zoomed to the optimal focal length, I imagine the extra resolution is nice bump up in capability, but I'm not sure what the extra dynamic range gets you in practice?
FYI It also appears to be
available from EMPIRE...
