IT/networking/ communicating between two networks

On a project where access control company needed IP addresses for their system. So we installed a Ubiquiti UDM-Pro (access control company already had switches for their equipment). When asked about parameters they didn't care what it was set to. We set the network up to all there equipment has been up and running for a couple of months. Fast forward to now and now they need to be able to talk to talk to the elevator companies network. The elevator company setup all there equipment on a network. Elevator company has their system pointed at with a gateway of for the access control companies server. At the moment I don't have much info on the elevator companies setup but have been told the line coming to my network is coming off a managed switch they have. I have tried a vlan network on my UDM-Pro setup in the range to connect the elevator network to mine. My problem is this is more involved than we ever get into. Our focus is more wifi and getting our a/v gear up and running. I cannot get either company to just change there equipment to the others network so my question is can I get these to communicate across the two networks and if so what I should be looking at to make it work?

My thought for this.

Is to VPN to the other network. I'm going to pause here since what is a VPN as well as setups is very well done on the web.

To be clear, I would NOT connect the networks but provide a way to access the other network from some PC or such.

Thank you for the response and direction to go in. Would this still be the case when the access control system needs to always be connected to the elevator system?

Since security would be an issue for such.

I like the idea of VPN better and better for the link(s).

Your run of the mill IT staff should be able to set this up. Mind you it may require some VPN hardware and software but no one thinks this is something we can do for free or "click here."
