please help.

you are confusing mac address and ip addresses.

You need to set a distinct ip address for each device.

Google dhcp reservation and static ip.

I don't think you provide any useful information that enable anyone to assist you. No brand, no model, no photo. There are thousands of different brand/model/version of devices there.

 

Was the mac address different right from the start ?

As you said it's a china set without brand/model. Could be from those small company that just copy/clone things from others.

The manufacturer might had used the same mac address for all their devices.

 

What you can do if you got no idea, get a cheap router, connect one of the DVR behind the router configured with a different subnet, set the router DMZ mode to be on and forward it to that DVR. Now the 2 Mac address will no longer be on the same subnet.

here are the photos and the the name (brand) is H.264 network dvr as far as i know. product No.C6704S-4I

 

the mac changed later on when i added my second dvr to my network.it some how copied my second dvrs mac address.

 

is there anyway i can change the mac address through telnet? or make iit work on one network.

can anyone tell me where can i find a firmware for this 8ch dvr.

i think if i change the firmware it might restore it to its default MAC address.

Is a link to tell you who mfg your dvr. If you google mac address you will find several articles that explain how this is supposed to be a unique code that only your device has and it is supposed to be hard coded into the device.

 

 

my mac is c8:22:02:04:2d:b1

 

so far no answers....
