IR seems to be working fine (at least it turns on, I don't know how it should work talking about proximity and so on).If your IR and IVS work you’re good to go
ps- you can update the firmware with it installed
IVS doesn't seem to be working, I have configured to Intrusion just as the Dahua Wiki says, but in Live View it doesn't show the draw I made as specified in the Wiki.
I've also followed this guide and it didn't work as expected
I know I can update the firmware with it installed, but since I'm running in my PC and I have a UPS here, I wanna play in the safe side.. So it would be safer to update here, since a powerloss could definitely kill almost any device updating its firmware
