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 a similar issue once, and switching between wired and Wi-Fi connections confused my router’s IP assignment. I ended up reserving an IP address for the camera’s MAC address to keep things consistent. Also, if your network ever seems like it's being weird or dropping connections, check if someone’s messing with it using an IP Booter—it can knock devices offline and make troubleshooting way harder.

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