Poe in nvr vs Poe switch

So I’ve been asking a lot of dumb questions here lately. I’ve had cctv since 2005 but now find myself wanting to learn more.

I’ve read a couple posts where the person has a NVR with Poe but chose to use a Poe switch instead. Why would be the reason for that?

2nd question about Poe+. I assume some cameras like PTZ need more power to run than provided by regular Poe. So in this case they would have to run a Poe+ switch. Is that correct?
 
A separate PoE switch allows the NVR to be located in places other than where the network cables from the cameras terminate. Folks can have the NVR located in an office/living room without having multiple network cables running to it.

A separate PoE switch also allows for the PoE devices to be on the same subnet as the other devices. NVRs with PoE built-in almost always isolate the cameras on their own subnet, which can make directly accessing them (like from the web browser on your computer) more difficult. Lately, some recent NVR w/ PoE firmware updates do provide a link you can click on to directly access the cameras on their own subnet, so that's lessened this concern for some folks.

Most PoE switches support PoE+, but to your point, you do have to make sure your switch is capable of supporting the specific PoE standards that your PoE devices need.

When I moved to this house and installed system, I ran a 2” conduit from my basement to where the NVR is. Then ran 9 cables for cameras and 1 for my network. So what you are saying is, all camera cables could have terminated in basement via switch and I only need one network cable to nvr. Lol. Ya, I did it wrong for sure. Unless there is an advantage to having all cameras terminate in NVR.

it is, a pain in the ass to get 9 direct bury cat5e cables into nvr for sure. Cables are stiff.

I went with a separate switch to keep the investment in the nvr as low as possible. If I need to replace the switch or nvr (due to failure or upgrade), the cost and work will both be lower. I also chose to use a managed switch. I use few of the features, but they are darn handy for monitoring and troubleshooting. When I was building the system, there were abundant good deals on used small business switches, making my total cost a bit lower than for the same nvr with poe built in. It does take a little research to make a good choice for which switch.
