Viewing cameras from Blue Iris server on multiple devices only using ethernet and no router; is it possible?

Hi!

I'm going to be setting up security cameras in an office, likely using Blue Iris, and want the system to be entirely wired, with no connection to a Wi-Fi network. From what I understand, it's as easy as connecting cameras to a network switch, and then connecting the switch to a PC running Blue Iris.

Then, I want basic live feed viewing functionality (ex. selecting two or three cameras to view) on several other computers. However, I don't want it to be done on Wi-Fi; I only want to connect the computers together wired. (It's a medical clinic; want absolutely zero risk). Is that possible? And, I assume that would be using the web interface?

Really appreciate your help, I'm very new to this.
