Better to connect NVR to Router or POE Switch?

Just curious if it is better to go NVR to Router & Router to POE switch or NVR to POE switch & Router to POE switch. I feel like the second option may be more stable as it eliminates the router as a middleman to get the data back to the NVR but I also lose 2 POE ports this way as I do not have an uplink on my Switch.
 
Understand that the cameras connected to the POE switch are getting IP addresses and routing info from your router. While I doubt it makes a huge difference, my preference it to connect the NVR and the POE switch directly to the router, if possible.
 
Makes no difference. The switch ports on your router are acting as a switch, it's not routing that internal traffic. Assuming that you don't have something more complex than a typical consumer router anyway and all are the same speed ports, a flat network, VLANs aren't involved, etc. There might be some trivial advantage to having two devices on the same switch that you could measure at a very low level but not in practical use. If they aren't the same speed and you had something like a 10/100 POE switch running the cams but gig ports on the router and gig on the NVR, then you'd probably want to pull the NVR/server/other device out to the faster net.

Thanks for the replies guys.

Alright, maybe someone could help me figure out why my NVR is now randomly dropping cameras for a few seconds at a time after swapped to a larger switch ( from 8 port 4 poe to an 8 port 8 poe+ ). The only thing I changed was the order of the ethernet cables from NVR to POE switch & Router to POE switch when it was not dropping cameras to NVR to Router & Router to POE switch.

The POE switch is 10/100/1000 and the router is only 10/100 but as you can see I am using under 30mbps so I'm assuming this shouldn't matter.

I prefer to connect the NVR to the PoE switch - this way if the router fails my camera system is still functioning. ( if static IPs it is more robust in this situation, if DHCP then when/if the cameras reboot and do not see the router there maybe issues )
 
Did you simultaneously switch the hardware and the connections? If you go back to the "old" connection order, does that resolve things? How are the cameras connected to the POE switch getting their IPs?

Yes, I switched the hardware and changed the connections at the same time.The Cameras are set to static IP. I just changed the connection of the NVR back directly to the POE switch to see if the issue goes away. It will be a bummer if I have to lose a POE port.
 
It shouldn't make any difference. Are your static IPs outside the DHCP range?
 
Well, you need to set the static IP addresses outside the DHCP range or you may get an IP conflict. This is why I generally recommend DHCP reservation.

It is an Unmanaged POE switch and the router is a standard ASUS wifi router. I don't know the model off hand.

I will go ahead and do this as a precautionary measure.
 
Ok, so I changed the connection of the NVR back directly to the POE switch to see if the issue would go away and it did not! Now I'm wondering if maybe my power strip is causing power fluctuation as this POE switch was working fine at my work.
 
You really need to correct the static IP issue first. It may not fix your problem but if you have the static IPs set within the DHCP range, it's incorrect. Depending on the router you have, it would probably be easier to use DHCP reservation as you can use the IPs that are already set. Otherwise, you'll have to reset the NVR to find them again.
 
Alright, let me explain my setup and maybe you can help.

My nvr is connected to a Asus router that is setup in repeater mode with a static ip of 192.168.1.10 (just now changed it as I believe it was conflicting with the gateway router) this router/ repeater connects to another repeater with a static ip of 192.168.1.100 which connects to the main router gateway with an ip of 192.168.1.1. All of my cameras are set to 192.168.1.110 - 192.168.1.113 and my NVR is set to static 192.168.1.199.

So it appears they are set outside of the DHCP range within the gateway router.

Is there anything else you'd suggest that I change?
 
What is the DHCP range in your primary router? It needs to be something like 192.168.1.20 - 192.168.1.70.

Also, when you say repeater, do you mean they are connected wirelessly?

I'm sorry, what changes are you referring to?

I actually do not know what the range is as I am using a hotspot. I would imagine it would be whatever the default is. No, the NVR is directly connected to the repeater, not through wifi.
 
Bare with me. I need to know if the boxes (Asus and other routers) are all connected to each other by physical cables. If so, the choosing "Repeater mode" on the Asus is incorrect.

In your primary router (possibly from your ISP and possibly combined with your modem), in the setup there is a section for DHCP. It will clearly tell you the start and stop addresses. I think we're getting to the source of your problems.

Oh ok, I get what you are asking. The Asus repeater is not directly connected to the 2nd repeater and the second repeater is not directly connected to the main router. As for the primary router, I think you may have missed that I stated above I am connected to a hotspot and do not have access to the primary router settings.
