As
pozzelo notes, the above preset http command can be used to execute camera-defined presets via the
Blue Iris webserver. It can also execute BI-defined http commands & scripts (Camera Properties>PTZ/Control>Edit Presets).
Note that BI’s range for n is 1-40... I have tried to directly edit the registry to create BI presets >40, but had no success getting them recognized by BI’s GUI (see this
post). That said, I just realized that I did not try to test a registry created preset >40 with the above http command. I’ll give that a try later today.
While you cannot ‘set’ a BI preset with an http command, you can probably modify
existing preset definitions (manually or programmatically) via the registry. I hedge a bit as I’ve not personally experimented with this. If I have time, I’ll experiment today.
