Eight cameras, one cable each, zero power adapters scattered around the rack. That's the whole point of the NVR1008H-8P. You run data and power through a single RJ45 to every PoE+ camera, then get 4K HDMI output on the monitor you already have in the office. H.265+ keeps your hard drive from filling up by next Tuesday. ONVIF means that second-hand Hikvision or Dahua unit you've got in the corner still works alongside the new VIGI set. New VIGI camera? Plug it in, it registers itself. No spreadsheet of IP addresses at 6:45am. Rack it, shelf it, done. Pull up live feeds and two-way audio from the VIGI app wherever you are
