Hi all, need some advice on this setup, a family member of mine bought a dahua system which incl a nvr DHI-NVR2104-P-S3 and 2 cameras IPC-HDBW1431E-S4. and now i got the task to set ip up. 
i managed to mounted it and connect the cams to nvr after som trouble (using the nvr as the dhcp, is it the right way? ).
while playing around in the settings menu (both nvr and cams) i could not find any option/section related to "Intelligence"/event trigger or IVS eventho the docs for the cams says that its supported, am i missing something??
also the firmware on the cams are: 2.800.000000.24.R,2020-10-14 and 2.820.000000.36.R,2021-07-23. what is the latest firmware and where can i find it, as i cant seem to find it via the official channels (dahua's page)
