I have currently 2 Dahua IPC-HDW5231R-Z cameras mounted, factory defaults.
This is the current Blue Iris view;

While reviewing the recordings, i noticed that the top right camera had artefacts now and then even tough it is closest to the POE switch which is powering the cams. What could have caused or is causing that? I am suspecting it is caused by the settings which are still factory default (on the cam).
I basically have a few questions, and you are of course free to point me to threads (specific posts please) which over my questions:
1) What settings should i use in Blue Iris for these cams?
Should i change anything here for better performance or stability?

Should i change anything here for better performance or stability?

2) What settings should i change/configure on the camera page?
Think of network settings, overlays, performance improvements that i should make etc.
3) With regards to firmware, i have these links:
ftp://ftp.asm.cz/Dahua/kamerove_systemy/_Firmware/04IPC/05-Eco-savvy%203.0/General/
ftp://ftp.asm.cz/Dahua/kamerove_systemy/_Firmware/04IPC/05-Eco-savvy%203.0/DH/
SHOULD i update, and if so, are these links still valid?
