I was looking for a single-port IP video server.
I found it on the internet shop website. I call!
I: "Say the question on the product item No. 1234, is it possible to connect the microphone?"
He: "Well, we do not have such information"
I: "So it does not exist?and "
He: "Yes, there is this thing, but we have no idea what a box is and for what purpose".
