hi, Im designing a system with a DS-7732N-E4/16P 32Ch DVR there`s about 24 cams 8 were going into a small 8ch POE switch and the output into one of the DVR`s POE ports also
a smaller 4 port POE switch will grab 4 camera feeds and dump them into another one of the DVR`s POE ports

My question is can this be done? IP wise its ok, POWER-POE wise im sure its ok as well but can one POE network port handle 8x 3MP cams ! [Only ~5FPS ea]

Regards Markos

Have you tested this configuration?
I may be wrong - I don't have anything to test this with - but I suspect that you will only be able to access a single camera via the PoE port that the switch is connected to.
The PoE port configuration is associated with a single IP address.
IP wise its ok,

How do you know this?
Maybe someone will comment who has tried this configuration.
 
"IP wise" as in its probably a POE network switch so you could have 255 IP`s on one port, not that you would do that.
I have used a switch inline before with one of these ports and I can access the whole sub-network [all the cameras and DVR] I do this to tweak the camera
settings at night.

Yes indeed. But the context of my comment was the availability of the cameras to be configured on the NVR, not the ability to access all devices on that PoE network.
Are you saying that the other PoE ports will be able to connect to the cameras on the external PoE switch connected to one PoE port despite nothing being connected to the other PoE port?
 
Yes it worked I had the POE ports 13 [IP 192.0.0.14] and POE14 [IP.15] connected to some bullets, Then unplugged POE ports 13,14 connected the cams to the 4 port POE switch then used POE port 16 as an uplink to the
POE 4port switch.

It then left the POE port 13 cam where it is and put cam14 on port16 with another IP [17] ! now im confused !

I can confirm the unit changed the cameras IP from 192.0.0.15 to .17 and put it on POE port16
might try a re-boot this fixes lots of HIK`s freakyshit

no re-boots the same
the problem is there`s 3 place-holders for 2 cameras mmmmm
 
this worked OK I have 4 cams on on POE port.
I did notice this new 32ch DVR`s password security policy wont let any cams run if they don't have a strong password.
Yet they wont let you change the "admin" login FAIL !
 
An interesting experiment - sounds like a first.
It also sounds like you have the NVR PoE ports configured as Plug & Play.
If you set them to manual - I don't think you will have the NVR reconfiguring the settings automatically.
 
I have this very same/similar question and I have just found your thread.

I'm picking this up, as a novice, after someone badly installed a DS-7732NI-E4/16P with 11 cams (2032 Bullets), 5 connected directly to the back of the NVR & 6 via a POE switch, into one of the POE ports on the back of the NVR. The LAN was then connected to the broadband router.

The problem we have is 2 of the 11 died due to water ingress, we replaced them with 2042 Bullets where I had to upgrade the firmware on the NVR to support the now required strong password. I also added a 12th Cam (7th on the POE switch) now I am struggling to get them all setup & recognised again by the NVR.

How do you configure a port to manual? I can see how to do it on the camera but cant see where to go for the actual port?

Also when I go back I will remove the 7th cam from the POE switch to see if the rest now work, perhaps 6 was the limit on one specific port?

If I connect the POE switch to the Gigabit Lan port, (which should take 16 cameras) how can I also connect this NVR to the internet for remote viewing?

Assuming the web GUI on the 7732 is much like that on 76xx/78xx - under Configuration | System | Camera Management (menu route varies with firmware)
Select a channel and click the 'Modify' button. At the bottom of the popup window is the 'Adding method' dropdown.

Hooking up multiple cameras to one PoE port is a very non-standard arrangement, with adverse effects on how the traffic flows.
Much better if possible to have the PoE switch connected to the router, as well as the LAN port of the NVR. The 16 PoE port channels pre-defined configurations can accommodate LAN-connected cameras when you change them to 'Manual' and specify the camera LAN IP address when adding.
That's provided the router Ethernet ports are ideally Gigabit, not 10/100. If 10/100, there may be some congestion on PoE switch or router port with 6 or 7 cameras each at 4-8Mbps, plus NVR traffic.

You could also do this - and it would be good to do if the PoE switch has a Gigabit uplink port - then you'd need also to connect a router Ethernet port to a spare port of the PoE switch.

Ah ok thats good to know, I am not near the kit right now (its not mine its a friends) but I can confirm that in the web gui of the 7732 it is seeing the cameras but saying they are offline, if I put the cameras IP in I can see the live view no problem so I need to check on this GUI again when I get the chance.

Yeah I wish the guys that originally set this up understood that they were shoving 6 cams through a 100mb port, its just not going to like it is it? I removed the 7th cam just now but the NVR didnt auto pick the others up again, I guess perhaps I could have added them in the GUI like you mentioned above though, shame I missed that one as I wont be back there for a week now.

POE Switch is gigabit up but the router is a BT home hub which does not have gigabit ports, also this router is then connected to the NVR via a powerline connection so not at all ideal really.

I did connect the cams from the POE switch to the LAN port but I could not get it to function at all, I assume some further configuration was needed in order to get this to work. Its a shame as I could have left my friend with all his cams working and recording onto the NVR without web remote viewing and this would have done him for now.

Due to the way that the property is laid out, and the installation that has occurred already it is not feasible to run cables from the cameras connected via the POE switch directly to the NVR, also there is no way to upgrade the router to support gigabit as there is no route from the router to the NVR without using powerline adaptors. As such my friend is considering getting a new NVR with two external gigabit LAN ports, one can be for the POE switch and one can then be for the internet. Good idea? Or am I missing something simple??

That will work OK with the PoE channel set to Manual, and the settings Modified to reflect the camera LAN IP addresses, which should be able to be set as needed using SADP..
If the gigabit uplink port on the PoE switch is plugged into the NVR, and there is another port to plug the powerline adaptor into as well, that should work OK.
The camera traffic will be all local to the NVR, and it's just the NVR that's accessed via the powerline adaptor, so no need to swap out the BT hub.
