How to set browser to connect to internet using specific device?

Both networks need to be in different IP ranges as Tracy mentioned. Leave the interface of your home router in dhcp, you will get a default route from thst one snd can surf the internet like that. The 2nd interface, in your shopnetwork, should be set to manual ip, pick a free ip outside the dhcp scope of that network and do NOT set a default gateway. Like this you can manually connect to the camera in this network and do the rest of your surfing over your home internet connection.

Bridging is btw no rocket science either, keep ctrl pressed and select both interfaces, there is now a right-click option available called 'bridge', only do this if you know what your doing, it's always a bad idea having two DHCP servers on the same network...
