What is your current network setup? Where are these Vlans setup on?
This seems like an odd setup that you need to change IP's to access the different Vlans, if you have something that is capable of setting up Vlans, then it would be capable setting things up to allow access across Vlans?
If you don't want everything on the main network to access all areas, you could create a 5th Vlan that only certain devices like the device you use to check on everything sits on that has access across all areas of the network. I do this at home as the Wife and Kids devices sit on a separate network to my devices which can go anywhere they like.
