Hi Tim. That sounds incredibly similar to something we're setting up for our MG car club here in Melbourne.We have 1x AW-HE40 cam with a Blackmagic ATEM-MINI mixer also taking HDMI signal from a laptop PC, and streaming to Facebook via OBS software. I want to dumb this down so people other than myself can run it, so would like to put together a simple app to move the ipcam to one of a couple of set positions, and initialise the ATEM a certain way. (We have all the manufacturer apps that can do this, but I want to fit all the HOW TO OPERATE instructions onto a single sheet! ;) ) VB is my preferred language too. Is there any chance of seeing your source before I start delving into aw-he40_ip_control_specification_aw-he130_aw-ue70.pdf ? :) Cheers, Ric.
