Updated firmware list

Agreed @IAmATeaf I just downloaded the zip file from the site for my NVR. Now I have extracted the zip and there are four files.

DH_NVR5xxxx.bin
Flash.bin
install.lua
partiontable.bin

What is the recommended way to update the firmware of the NVR? I have researched a bit but there seem to be many different methods. I just would like to avoid bricking the NVR and other devices I am trying to do updateds for. Thanks for the help!
 
I was able to update my firmware on the NVR through smart pss. You just select the DH_NVR*.bin file. It is pretty simple.

However, under devices in smart pss I only have the NVR listed. I would like to upgrade their firmware but am not sure on how to update them individually.
 
FYI updating the NVR is very simple through Smart PSS.
 
Andy usually posts firmware much newer than what is currently available on the Dahua website,
