Dahua: form factor vs price differential

veert said:

Hello everyone.

I'm looking at these two:
IPC-HUM8431-L4
and
IPC-HUM8431-L1

Am I right in thinking that while the latter requires a base (E1), the former is self-sufficient and can be connected to an NVR directly?

The latter is roughly $120 more expensive vs. the former - is that the price of miniaturization, then?

Thanks!

Yes, I overlooked that - my apologies.
The question then becomes: why is the former lens unit so much bigger vs the latter? If both require the main box, why would one pick the bigger one?

Oh, is it just the question of square vs round, then. It's crazy, but the pictures somehow create a totally different impression until you look at the specs.
Same size, indeed. Sorry.

Actually, this one

does seem to not require a base unit. At least, it doesn't say so on the page. Or I should assume that all such lenses need a base for some underlying technical reason?

I do understand, a smaller unit (or one w/o a base) will be missing some features, but that's not my point.
