Hi all,

First off - To the experienced guys I am going to apologize in advance for what I am about to ask . If you could have mercy on this noob it would be greatly appreciated:winktongue::lmao:

In order to get your cams recognized on your network what is the most common / recommended way of doing so? temporarily change network to same ip range as cams, log into each cam and change it to have the same ip range as network in normal state?

for instance my ipv4 is 192.168.0.17
cams are default 192.168.1.108

So go in change all cams to 192.168.0.XX ?

then once all cams are working make sure the whole deal is behind a VPN and call it good?

Thanks:headbang:

Yes, you got it. Also in your router restrict each camera's IP from accessing the internet.

Or.. if your PC has two ethernet ports, one goes to your router, and the other to the POE switch that the cams are powered from. The POE switch is not connected to the router in this case. This keeps them off the internet as well.

Thanks walrus. My computer does have two Ethernet ports. One is for the internet and one for the Poe switch.

What if I wanted to remote access? Same deal but add a ethernet cable from router to Poe switch as well? Is there anyway to do it with only the one internet cable to computer?
 
No additional cable. Your remote access is to the computer running BI, which is pulling the streams from the cameras.

ok , but you said earlier that if the the internet goes to one port on the computer and the other port on the computer goes to the POE switch that it will keep the cams off the internet?


Im guessing you mean I would not be accessing the cams directly, but instead would be accessing blue iris on the PC remotely which would let me get live view, playback etc?

thanks again.
 
thanks again @Walrus

so just to confirm, even if the network with the cameras has the same ip range as the network with the internet, the internet cannot access the cams because they are two different networks? ( each network has its own Ethernet port on comp)
 
@clean
No, don't do that. There will be a conflict. Since you have the two ports, you need them on separate subnets.

Sounds like from your first post that your regular home internet subnet is 192.168.0.xxx
Change the ipv4 of the 2nd port to 192.168.1.1
Make your cams 192.168.1.xxx (just not 192.168.1.1). eg make cam 1 192.168.1.101, cam 2 192.168.1.102

@clean,
another thing to remember

When adding that 192.168.1.1 to the second NIC connected to the PoE switch, don't add a Gateway to it.

Thanks @58chev

can you point out where to check for this? thanks.

If you open a command prompt, type "ipconfig /all", there you'll see all TCPIP information per adapter. Make sure there is none mentioned on the "private" adapter. If there is: open network adapter options (google on how to do that under Win10, it became complicated) until you enter the TCP/IP settings v4 of that adapter and remove the gateway.

Good luck!

Yessir, that's affirmative!

Now, if you want to be 200% sure that your windows is not rerouting packets from the inner camera network, you can put a pc/laptop/... on the POE switch, manually set (for example) 192.168.1.224 ip address and try to go to Google. I bet that it won't work, so your cams won't be able to phone home either.

Good luck!
