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

If you want both devices active at the same time one of the routers needs to be configured to a different IP range on the local settings! Move the "shop" router to 192.168.5.1 instead of 192.168.1.1. It isn't hard to change.

However, you could just click the disable button on one adapter. Right click the adapter icon, click disable. That way you could select which adapter was in use at any particular time. Click disable on the "apartments" connection/adapter use the "shop" adapter. Reverse the choice to go back and forth.

Your other option is simply port forward to your CCTV connection on the shop router and go to it from the public IP! Then you only need one adapter period.
