I am in the same situation with my HANKVISION camera. Before I bricked it with the "newest firmware update" ;), I read out following information with ipctool:
board:
vendor: Hankvision
model: V6202IR-BRV0500
chip:
vendor: HiSilicon
model: 3516AV100
ethernet:
mac: "00:2a:2a:2c:21:04"...
It's definitely much worse than with previous firmware... also the total blurred image after clicking on a position button without actually moving as the camera already is on this position didn't occur.
And I didn't even notice the focus before, now it's annoying...
With this firmware (IPNC_S2l2.1.1_build20170314122826.zip | Kernel flashed too) I have some problems with focus of the camera. It takes very long until picture is sharp and if I click on saved position button twice then it once more gets blurred and needs about 2 secs. to recover sharpness...
