You can but sort of defeats the object as you may not have the freedom to hide your NVR. In your situation it would probably be best to just wire all your cameras to your NVR and see if you can run enough cables from your cameras to hide / secure your NVR. Or if your funds are there buy another POE switch with more ports. But like I've said before your original solution works fine, I was just offering my 2 cents as if you are unlucky enough to get hit at least your footage of the scum may be kept safe due to the fact they couldn't find / didn't know where your storage device (NVR) was.OK but if i have 5 poe cameras and on the switch are 4 poe slots..Can i one camera plugging in poe slot in NVR? It is best solution for me?
the ports on the nvr are irrelevant...the "channels" is what sets a hard limit.So if it's feasible to connect cameras to an external POE switch, and then just connect the POE switch to one port of the NVR, is it still necessary to buy a 8- or 16-port NVR? Could I buy a 4-port NVR and then hook up 8 or more cameras to it using a separate POE switch? Or do the "guts" of the NVR need to be scaled up in order to handle the load of more cameras?
Sorry if this is a newb question, but I'm a newb.
So I assume that typically the number of ports mirrors the number of channels? They wouldn't sell a 4-port NVR that supports 8 channels?the ports on the nvr are irrelevant...the "channels" is what sets a hard limit.
No that is not correct...they have 32 channel nvrs with 16 ports...the others are connect via a switch someplace on the networkSo I assume that typically the number of ports mirrors the number of channels? They wouldn't sell a 4-port NVR that supports 8 channels?
Thanks, this is all good information to consider as I try to figure out the best system to buy for my house.No that is not correct...they have 32 channel nvrs with 16 ports...the others are connect via a switch someplace on the network
In this case is there any significant difference in terms of performance with regard throughput to the NVR from all connected cameras being local vs. a switch hop and, presumably, a gigabit link cable? Are there any differences from a networking (subnet) perspective?Yes that looks good.... One suggestion, If you have enough ports on your POE switch you could wire your cameras direct to the switch then one feed to the NVR. This will allow you to hide the NVR somewhere secure in your property.
Can you recommend any non-POE NVRs? I haven't been able to find any that aren't POE-equipped. Since realizing this was a possibility, I'd much rather put the NVR near my living room TV, and terminate all the cameras at a POE switch in my equipment closet than keep the NVR in the closet where I'd need to find a way to stash a monitor.If you're not going to use the poe ports on the nvr than don't buy a poe nvr. Most people would recommend you don't anyway, for easier installation and easier camera settings configuration. I happen to prefer poe nvr but that's just me.

In terms of alarm outputs...
The model I posted there is 4 alarm inputs and 2 outputs. Not messed around with Z-Wave so can't give you a concrete answer but if you want any information regarding config of these inputs, then this link is very informative NVR/Recording Setup/Physical Alarm - Dahua WikiIn terms of alarm outputs...
Alarm Action:FTP Photo
Is that the sum total of its capability? No possibility to output to a trigger that could be routed into a Z-Wave smart home scenario?
