I purchased a RLN36 NVR, a POE switch, some outdoor rated cable, etc.. etc...
This weekend I hope find some time to start experimenting with it...

My question is. Comment, then question is:

You have the cam (1 or more) > that connect to the POE Switch> One of the POE switches ports connect to 1 of the 4 Lan Ports on the NVR> then it has a port that connects to one of your routers LAN ports. According to all the diagrams I've seen.

If you are still reading, my question is:
Does the NVR do DHCP and hand out IP addresses to the Cams that connect to it, or does it just forward the IP requests from the Cams through the switch and NVR to the Router and it it does the DHCP/Address assignment?

IF the later, how big of a deal is it when you change your router???
I have a crappy Linksys that at some point, I know I'll replace with something newer and better.

Where can I get a list of the actual power requirements for each of the IP/POE Cams???

I'm just ordered a Reolink RLN36 and a few 16TB HDs, next I want to figure out what POE Switches to buy. I kinda doubt I'll ever hit 36 Cams, but I'll have a bunch for sure, probably at least 4 PTZs and then several static cams.

I want to know the Voltage and wattage of each of the Cams. so I can keep an eye on the switch's power budget and not overload it.
The only Cam I could find was one of the 823As. I read somewhere that it was like 24 watts. I can't find it now and I can't find the others.
