same IP address in IPC2211ER3-PF36

[mohammad mashhadi]

Hello
I have 2 IP camera that both of them have same MAC address.
the NVR can't handle because they have same MAC address.
My question is: How can i change Mac address of IPC2211ER3-PF36.
thanks

What method did you determine the 2 MAC addresses are the same?
Is it because the label on each of the 2 cameras has the same MAC?
Or do they show up as the same in the NVR?

If the latter (NVR), I would unplug both cams, delete them in the NVR, reset the cams then re-add to the NVR.

If the 2 cams are labeled with the same MAC on the camera then they most likely do have the same MAC and I'm pretty sure you won't be able to use both cams on the same NVR. That's a manufacturing mistake that should never have happened.

Both of them have same MAC address when I search devices in network I can see the 2 MAC addresses are same
I use both of them on same NVR
I know I can't use both of them in same NVR
But I'm searching for a way that I can change one of the MAC addresses?
Is there any way?
Help me!!!!

If you connect up to the device serial console, you can change the environment variable that specifies the MAC address, the 'ethaddr' below.

uboot # printenv
bootargs=mem=512M console=ttyAMA0,115200 mtdparts=hinand:1M(boot),9M(kernel),90M(program),1M(cliinfo),1M(clibak),1M(mtd_runtime),16M(config),8M(calibration),512K(update),-(other)
bootcmd=nand read 0x82000000 0x100000 0x900000;bootm 0x82000000
bootdelay=1
baudrate=115200
ipaddr=192.168.0.13
serverip=192.168.0.10

You'd need to open it up and find the 4 pads that provide the 'serial TTL' interface to the serial console.
Even if the camera has the 'enable telnet' capability, it's unlikely to have the ability to see and change the bootloader environment variables via that method.

If you log into both cameras Individually..they have the same Mac Address ? Not likely, I do know some Uniview cams do not show up on a arp command. I can also tell you that I have a Dahua Nvr that will go out and find ghost cameras that were previously installed, I have not tested why but you might want to default your Router, NVR and both cameras and see what happens..I bet that will solve it. I think my NVR was pulling its info from my routers arp table that was fubar, On the Dahua Cams there is a check box for ARP ping and if its not checked, the router gets confused if you change IP address on that cam.
