DS-2CD2086G2-IU about 160$
DS-2CD2087G2-LU about 240$
In my opinion, ColorVU or Full-color is not good because of the F1.0 Aperture, that have less DOF
Why dahua dont have a quality 8MP camera?
While Hikvision have the G2 8mp min.illum 0.003lux camera?
5442 and 3241 and 2231 is bomb
But 8mp Hikvision wins
Maybe Dahua is little late because of the covid ?
What you guys thinking?
Intresting..
About number 6
"6) Do Not use uPNP, P2P, QR, do not open ports,"
Not use P2P, QR, Dont open ports...
How should I view the cameras remotly without one of those options ?
Are you sure its HFW2831T-ZS?
Or maybe its HFW2831T-ZS-S2?
Anyway if it the first option (not S2) then there is a new firmware here:

Choose 'Download' then 'Firmware'.
Latest firmware date is 07/01/2020
I think there is a problem with the encoding of Hikvision NVR and Dahua camera.
Check that all the encoding both on IPC gui and NVR gui are in the highest level.
The 5442 camera is really good camera. And all the photos you are posting looks like sub-stream!
Stop changing camera settings and...
