Actually I’m using a 5216 16P now that has 8 dead internal ports due to a lightning strike. It was a buddys, I have cameras on some of the remaining good PoE ports and others on an external Netgear switch. The NVR is fineThere's no correct overall answer. If fan noise is an issue, you might be sorry having the built in POE switch. With the integrated POE switch, if the switch part fails you also have to throw away the NVR part, and vice-versa. Depending on your wiring scheme you could be better of using external POE switch(es). On the other hand, with the built in POE switch, setup and troubleshooting is simpler.
One downside: As mentioned in a previous post the Dahua POE NVR's have very noisy fans. Forum users have discussed this in other threads too. This would be a potential problem in an installation like mine. Fan replacement has been suggested as a remedy when the noise is an issue. But I have no experience with Dahua POE NVRs, so this is all hearsay to me.I can’t think of any real downside with an NVR with built in PoE.
Using an external POE switch with the NVR and Blue Iris on the same local network should work fine. However I'm not a Blue Iris user so no experience doing this.If you put all the cams on a POE switch, can you run both Blue Iris and the NVR with streams for both?
I don’t see why not….Hey dumb question. I'm slowly losing my technical knowledge to Sumt-heimers...Sometimes i remember shit, sometimes I don't.

thanks for the perspective, it helps!That is totally up to you. If you can run all the cables back to the NVR, then it makes sense to get one with POE capability. If you cannot get them all back to the NVR, then a non-POE makes sense.
Some will suggest that it is better off to get a non-POE so that you can control the POE switch and one less thing for the NVR to have poop out.
the way this old house is constructed & where the current LAN equip is, it was too costly & difficult to get all the IP cat6 cables to that room. so some were pulled to another closet that has LAN connectivity. years ago the old analog coax cable was pulled into the LAN equip room when a new roof was added, which made access and drilling through wall studs easy. didn't have that luxury for the cat6 this time.This question has come up before and it seems most recommend getting an NVR with integrated POE. Mainly to ensure the cameras are isolated from the local network.
FWIW, I'm grappling with this decision myself. Moving to new house and leaving my old Dahua system behind. I'm currently using two external POE switches with 10 cameras total. It has performed well. The new home will have more cameras, but all will home run to the same closet.
In my installation I've integrated a couple cameras into my home automation. This needs the local network to have access to the cameras' API. But maybe one day I'll need to isolate my cameras using the internal POE method.
Lately I've been learning towards purchasing a Dahua POE NVR (NVR5216-16P-4KS2E)). It will allow me to use external POE switch or the internal POE. It adds to the cost, but not enough to kill the deal for me.
TLDR; Like you, I'm searching for compelling reasons to do one over the other.

another good perspective. leaning towards using both, get a NVR+PoE that allows an external PoE switch too. have some more comparing to do but after reading @ThomasCamFan's post i'm leaning that way. seems quite flexible but i'll see.There's no correct overall answer. If fan noise is an issue, you might be sorry having the built in POE switch. With the integrated POE switch, if the switch part fails you also have to throw away the NVR part, and vice-versa.

+++! i had not known this before. thankful for your post and others who have mentioned it.I can’t think of any real downside with an NVR with built in PoE.
It allows you to use an external switch along side the PoE ports simultaneously, and if the internal PoE takes a shit, you can still use an external switch.

doesn't your NVR have much of the same functionality of a basic VMS, for home use? theNVR will have an interface (an app or web access) for retrieving-viewing your recorded & live surveillance footage, yes?The whole purpose of an NVR for me was because it is an 'all-in-one' unit with the POE switch and small form factor.
If you got with an external switch, then you might as well treat yourself to a VMS.
Many here will say a VMS like Blue Iris blows away the functionality of an NVR. There are way more options and possibilities.doesn't your NVR have much of the same functionality of a basic VMS, for home use? theNVR will have an interface (an app or web access) for retrieving-viewing your recorded & live surveillance footage, yes?
My current NVR (NVR5216-16P-I) does have good analytics for most home users.doesn't your NVR have much of the same functionality of a basic VMS, for home use? theNVR will have an interface (an app or web access) for retrieving-viewing your recorded & live surveillance footage, yes?
So absolutely correct response you got 26vLHz.Many here will say a VMS like Blue Iris blows away the functionality of an NVR. There are way more options and possibilities.
