It's worth noting that you will have to set up firewall rules on your new router to block internet access to specific vlans. By default your router will probably allow all traffic between all vlans.
If you want to segregate the video doorbell it works the other way around, allow internet access to that vlan and block access to your main vlan.
Could you answer some VLAN based questions please?
