Hi. Why do you need to change the Mac.

[jeromephone 6]

I think that your mac address is supplied by the MFG and is supposed to be only for that particular device.

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.

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.

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.
