Cannot find IP CAM

So this "switch" who is distributing DHCP addresses

I feel like his switch is not assigning IP addresses, and his "router" is still on 192.168.178.X. So his manually assigned 192.168.1.X devices can't talk to each other, because they are sending packets to the switch, and the switch is forwarding them to the router and the router is sending them out to the internet.

Indeed, and to make things more complicated: Topicstarter can not tell which IP his camera has received from which DHCP server.

The switch would have to be a smart switch set up for IP routing for that (unlikely) to be the problem, as opposed to just a a layer-2 switch where it's all about the MAC addresses.
But I suppose stranger things have happened.

@bartje006 Also curious as well as @catcamstar that your diagram has the switch labelled as DHCP.
Presumably it's not a used Enterprise switch bought off eBay, still configured from the original network?

The modem/router assigns ip adresses (as far as I know). The switch settings are set like in the image below (current ip = 192.168.178.158).

I've set the range on the modem to 192.168.1.x. Then it assings IP adresses to PC and switch. But this still did not work.

Nvm, I just tried it on my own setup, kinda reversed things because my CAM network is 192.168.1.X lesson learned just go do a test before typing something up.

  1. I took a perfectly working PTZ camera I had laying around, IP:192.168.1.192 and determined it's MAC hardware address. (this might be tough, it wasn't on my camera nor box, might work without this MAC and step #6, I didn't test that).
  2. I connected it to the same POE switch that all other 192.168.1.X cameras are connected to.
  3. I logged into it and changed the FIXED IP of that camera to 192.168.178.192 (this was to get me in the same broken state as you)
  4. immediately lost connection to it in Blue Iris, also can't ping it.
  5. on PC, opened an elevated Command Prompt
  6. typed: ARP -s 192.168.178.192 HW:MA:CA:DR:EE:SS (<- but actual MAC address)
  7. ping still doesn't work
  8. on PC, changed network setting for the port that is connected to the switch that the Camera is connect to (because I have dual-LAN NIC configuration, 192.168.33.X connects to my whole network via NIC#1 and 192.168.1.X connects to camera-only network via NIC#2)
  9. on NIC#2, changed IPV4 settings to add IP address range (under Advanced TCP/IP Settings) I added 192.168.178.1 mask: 255.255.255.0
  10. now ping works to this one wonky address on the switch
  11. I was able to login via camera web interface and change the IP to something correct for that network
The problem I encountered trying (my own suggestion) the subnet mask 255.255.0.0 was the camera was still not reachable unless I added the entry to NIC#2 as above.

Give us a same shot as above but click on the "Ports" tab.
 
Hi, thanks for your help!
I tried to recreate this, but can't find the mac adress of my ip camera. Also, where can I find the advacned TCP/IP settings? Thanks!
 
Hover over the port six and you should see the name assigned to the camera, then click on the clients tab on left to find that name. May be a name or MAC address. Once you find that the column to the right of that will be the ip address.

On windows 10 (I dont know what you are using):

  • enter: ncpa.cpl in Windows search, click the one it finds that's a "Control Panel Item"
  • Select the network adapter that is wired to the switch (you might just have one, or you might have a wired and a wifi)
  • Right-Click, Select "Properties"
  • Find: "Internet Protocol Version 4 (TCP/IP)" in the list of items on the connection
  • Click "Internet Protocol Version 4 (TCP/IP)" to select
  • click "Properties"
  • Find "Advanced" button, click that.
  • Under the box titled "IP Addresses", you hopefully already see your manually configured IP address 192.168.1.X , or if you reverted all your prior changes you might see "DHCP Enabled"
    • (if your PC is using DHCP, you might have to go back a screen and change it to a MANUAL IP
    • use something like 192.168.178.250 or even the address it is currently assigned by the DHCP server
    • just don't overlap any other potential DHCP devices, or you'll have an IP conflict and ton of stuff wont work
    • subnet: 255.255.255.0 to continue
  • Click the "Add" button
  • Enter the suspected IP network of the camera, probably 192.168.1.1
  • Enter subnet mask: 255.255.255.0
  • Click "Add", it should pop into the list
  • Click "OK" like 4 times
  • You can always come in and delete this later after you get the camera fixed, or just leave it so next camera will be easier.

I did exactly this, but still get 'Host destination unreachable' when pinging to 192.168.1.108.
 
That says to me that it sees something and is drawing some power but not fully connected. Have you tried to default the camera? Is there a reset button?
 
Is there anything else connected to the switch? If so you can hover over that port and you should see what I was referring to.
