Can someone help me sort out this confusion of a Poe switch and how it works ?

Hello everyone I have a quick question regarding a switch and how it works. So im installing 6 Poe cameras and all the cat 6 cables terminate in the attic. Well my router is two story's down and I want the NVR in my bedroom in between both, is it possible to have all 6 cameras connect to one switch in the attic and only connect one Ethernet cable to the NVR ?

The simple answer is "yes" but there are assumptions involved and details that might need to be defined. For instance, for wanting the NVR "between both", does than mean physical location, or with respect to the wiring connections, or both? Does the NVR have POE ports? Will you be using static IP addresses (recommended) or DHCP? Are you wanting to have remote access? Are you wanting to access the cameras and/or NVR from a computer on the local network? Is the attic switch a POE switch? More details will get a more accurate answer.
 
Okay I apologize let me explain a bit clearer, my home is 3 stories. The router is in the downstairs / lower level . My bedroom is on the second level and there's two bedrooms on the third level with one having crawl space access were all 6 cat 6 cables connect. This is a hiseeu Poe camera system. There are 8 poe ports one lan port and one HDMI port. I was under the impression the cameras all had there own address and the NVR only requires Internet for remote access. I wanted to put the NVR in my bedroom so i could view on the TV , it's not far to drop a cat 6 downstairs to the basement , but I don't want to have to run the 6 cables down if there's a simple solution to keep it clean and a little bit easier. I do have another idea on keeping the NVR in the attic and just dropping one cat 6 downstairs and a HDMI cable to the TV , potentially a 50 foot USB extension for the mouse if I'm unable to get a wireless one to reach the NVR , but I'm still running 3 cables pretty far that way .
 
I'm not familiar with the hiseeu brand. What I'm saying here is probably correct, unless the hisseu NVR works very differently from what I know.

- If you want to use the POE ports on the NVR, you must run a separate cable to each camera. The NVR will assign an IP address to each camera automatically. The cameras would not be connected to your local network. You would then connect a single cable from the NVR to a port on the router if you want to reach the NVR remotely or from a computer on your local network.

-If you want to run a single cable from the 3rd floor down, you need to have a POE switch up there. You would not use the NVR's POE ports at all. If you want access to the NVR or cameras remotely or from your local network, you'd connect the POE switch and NVR to the router. Otherwise you could just connect the POE switch to the NVR and have a little isolated network (I've never set it up this way, it seems like it should work).

- Similar to your idea of the NVR in the attic, my NVR is in the crawlspace and I use a wireless mouse and wired monitor connection to it. I do, however, do all of the viewing and management from a PC connected to the network.

You may very well need to learn some basic networking to determine the best solution. Things like what switches to, static IP addressing, dynamic IP addressing, as examples.

In some POE NVRs you can infact run 1 cable per 4 cameras in other NVRs you can run 1 cable for 8 cameras depends on the NVR.. However in a setup without a POE NVR cameras in some NVRs can work in a normal NVR state and connect all cameras over the normal ethernet port.. So things to keep in mind.. Cameras to the NVR without the Switch you would be best off. Setting up a the cameras to your Switch will give you access to the cameras WebUI if it offers one and add that many more options for attacks at each IP.. IF the Switch is Managed and has options for VLAN you could setup the switch and only you would have access if you gave your computer access to the normal VLAN and the cameras VLAN..

What is the best thing to do. Well if it is like all my Amcrest NVRs that has the ability to run All cameras through the normal Ethernet port of your NVR that is what I would do.. Then there is no extra wiring that you would need to bring to your NVRs POE ports just the normal ethernet port.. However if you wanted to run them on the NVRs Switch again if your NVR has the ability normally if you put a Ethernet cable from Switch to Port 1 that could fill cameras 1-4 then another cable on port 5 and that could fill 5-8. Personally I would make sure that the cables from your switch is blocked to your normal network because the Switch in the NVR might try to hand out IP addresses to your normal network devices on a device reboot.. Again if the Switch is a managed switch you could do this..

Setup cameras and setup to have your NVRs POE switch port IP address.. Like for my home network I use 10.0.0.xxx and for one of my POE NVRs the switch IP is 10.2.25.xxx and so all the camera that I would want to connect to the POE using what I call a pass around cable I would setup with 10.2.25.65, 10.2.25.66, 10.2.25.67 and so on.. Pass 1 cable to port 1 for first 4 cameras and another cable in port 5 for the other in your case 2 cameras..

However easiest is just to setup the cameras on your LAN and let the NVR with its ip address using its normal ethernet port in my case would be 10.0.0.225 for that NVR and all cameras in the 10.0.0.xxx range can be added to my NVR just like a normal non POE NVR would using just the 1 Normal ethernet port..
 
Thank you all so much for the replys. I appreciate the help, I went ahead and ordered a 8 port Poe switch from the same manufacturer, it has two uplink ports one for data and one for the NVR. So I should only need to run 2 data cables , one to my bedroom and one to the router. That elimates a good bit of trouble .
