Hello all I just purchased a Hikvision DS-9632NI-I8 NVR upgrading from a DS-7616NI-K2-16P NVR and I am a little confused on the setting up of the two Lan ports and the advantages and/or disadvantages of each configuration. I currently have 12 IP cameras running through three separate switches that then connect to my router and three cameras that run directly out of the poe ports on the back of the NVR.
