Dahua naming system - lost

[TobiasF]

Hello,

is there any system in Dahuas's naming convention for cameras?

I try to understand the difference between different Dahua cameras to be able to select the best for my needs and budget. I am lost!
I am not focused on this specific type, but when I search for IPC-HFW5442 I get listed 19 different versions on Dahua's product page:

• IPC-HFW5442T-ASE
• IPC-HFW5442T-SE
• IPC-HFW5442H-Z4HE
• IPC-HFW5442H-ZHE
• IPC-HFW5442E-ZHE
• IPC-HFW5442E-Z4E
• IPC-HFW5442E-ASE
• IPC-HFW5442H-ZHE
• IPC-HFW5442H-Z4E
• IPC-HFW5442H-ZE
• IPC-HFW5442T-SE
• IPC-HFW5442E-SE
• IPC-HFW5442E-Z4E
• IPC-HFW5442T-AS-LED
• IPC-HFW5442T-S
• IPC-HFW5442T-ASE
• IPC-HFW5442E-S
• IPC-HFW5442E-ZHE
• IPC-HFW5442E-ZE

Can I identify specific functions and features by the naming convention without comparing the full spec of each device?

What I believe to know so far:

1. H - ?
2. F - (D=turret/dome; F=bullet)
3. W - ?
4. 5 - series (5 series)
5. 4 - resolution (4MP)
6. 4 -?
7. 2 - ?
8. T/H/E - ?
9. xyz - ?

This is old but might help some. You list of 19 models doesn't even include the black ones that add a "B" to the end part.

Thank you!
This is what I am looking for.

I hope, I now better can narrow down the list. (Not limited to the 19 listed in my example.)
