IP Adress - wire connected and WIFi

[Magik.spod.lasu]

Hi. After 10 years work of Escam cameras, I'm replacing them with UniView.
The question is: Why do old cameras allow a common address IP, and new ones don't?
The cameras are connected to the network simultaneously via LAN and WiFi. Old cameras allowed a common address for both of their network cards.
In new ones, each camera must get two separate addresses: cable and wireless. This complicates sharing the stream for the NVR.

Can you advise me something?

Just guesssing here but could be that a wired camera will most likely be connected to a POE NVR and so will be on a private subnet, different from the LAN and WLAN (Wi-Fi) subnet so 2 interfaces/circuits necessary.

Or maybe in later years the FCC decided that each NIC, wired and wireless, would have its own MAC address for identity purposes.

I had the same issue—my camera showed two IPs when both wired and Wi-Fi were connected. I just disabled Wi-Fi on the cam, and it stuck with the wired IP.

I’d rather they had separate IPs for Ethernet vs wireless.
