Lost access to the network when you connect the ip camera to the Ethernet port?

Question

linux

There is a single-board Raspberry pi 4, to which an ip camera is connected via twisted pair. For the ethernet port, a static IP is registered, the camera itself also has static IP.

Malinka has access to the network either via wi-fi or via a usb modem, but when the ip camera is connected to the Ethernet port, Internet access falls off, while the web interface of the camera itself is available. As soon as I take out the twisted pair cable from the connector, access to the network appears.

Answer 1

Look at the output ip r, for sure you will find the default route through the ethernet interface there.
Remove it and everything will work as expected.

Answer 2

Thanks a lot to the people who helped, the problem was solved simply - the camera had to be placed on a different subnet.
