Well, I think I got a work around. The cameras are actually on a /16 subnet, which exactly matched my network. if I reconfigure the camera network as a 172.16.25.x/24 everything works, and it doesn't seem to mess up the dvr executable listening on all the ports. # route -n Kernel IP routing...

Just when I think I got it figured out, Swann has just got to make it difficult....there is no config file I can find anywhere on the file system. They have one executable that does everything called "dvr". Once you start it, it whacks all interfaces and reconfigures it with a hardcoded...

I must have missed that in the manual, let me go look. There is nothing in the manual that says you can change the IP address of the cameras.

Crap, your right, replace every where I say 32 with 24.....can't multiple 8x3.....had 255.255.255.0 notation right :)

Sweet, I found this site...someone actually found the serial port.... http://sirlagz.net/2017/03/02/poking-the-swann-nvr-7400/ poking around I can actually change the subnet of the Cams but it doesn't look like the cameras are getting their IP from the NVR, must be hard coded on the camera? I...

The network is 172.16.x.x/16 or 255.255.0.0 The NVR Cam subnet is 172.16.25.x/24 or 255.255.255.0

Maybe I don't understand your solution.....here is a little more on how my network is configured. Everything plugs in to one switch. Internet--------Gateway------------SWITCH----------NVR--------Cams 172.16.0.1 172.16.x.x 172.16.25.x In order for the NVR...

Returning it is not an option since it's been too long, and yea I could reconfigure my whole network and allocate individual /24 networks around the .25, but I don't want to, because I like how I have the vendor pools setup now in the DHCPd and I don't want to change it....I'd rather waste my...

The cams are on separated runs, however putting something between the cams and the NVR I don't think will help. Putting something in front of the NVR before my switch yes, VLAN, NAT, I just don't have the room for that other box to configure something like that, and I don't want to because I'm...

1) correct 2) correct (default nothing on the NVR that I see allows me to change this) 3) With the NVR WAN getting a 192.168.1.x/24 address things are fine. However my network runs a 172.16.x.x/16 subnet, which I can't change. 4) correct, OSD GUI with monitor on VGA port 5) correct, can't find...

It's not an IP conflict, it's a subnet conflict. An IP conflict would be reported on another PC, running windows. A subnet conflict is only going to show up on the device itself. When you have a subnet conflict the box can't even answer a simple ping, at first I didn't know the IPs of the...

I've never checked the Web GUI, unfortunately Swann's VGA GUI doesn't have an option that I can find for it.

Yes, that is what the problem is. The NVR is configured for a subnet that conflicts with my network. For example, my network gives the NVR an IP of 172.16.4.10. The NVR creates subnet 172.16.25.x for the cameras that are plugged into the LAN/PoE ports of the NVR, so when I plug in camera1 it...

I have a NVR-87400 and all the camera's are set for a subnet of 172.16.25.x/24, my business network is 172.16.x.x/16. I can't change my business network and would like to change the subnet of the cameras to something like 192.168.1.x/24. Technical support was not very helpful as I had problems...
