This one's for the question "can I use my existing cameras, even though they're from different vendors?" Yes — and this diagram shows how.
Read the Local Area Network as a single self-contained box. Four cameras of different makes and models (Sources 1 through 4) all plug into the same network switch. From there, two computers handle the show: a Switcher Software Computer for cutting between feeds and an Iris Studio Computer that bridges everything together.
There's no internet in this diagram, and there's no requirement that every camera come from the same product family. Iris normalizes the feeds so a mixed-brand fleet behaves like a homogeneous one.
Use this as your reference whenever someone asks whether they need to standardize their hardware before adopting Iris. The honest answer is no — they can keep what they already own, mix in whatever they buy next, and Iris won't complain. It's especially relevant for customers who've already invested in cameras and don't want to throw any of them out.
This is also the cleanest "all local, no cloud" example to show when discussing what Iris does when the internet is irrelevant to the use case.
