I Need A Network Guru To Walk Me Thru This (Cross Subnet Sharing)

I have some cameras installed by a third party that we need to view. They have no problem letting my group view them, but this is a large enterprise network and I am not sure I have the networking skills to make this work reliably. Can anyone here provide some input?
