I good test to try is to manually move the PTZ using the BI controls. Move it to a new spot and let it sit and see if it returns back. Mine does after 30 seconds.
I will post screenshots of the PTZ settings. I do not remember having to do anything under that tab, but maybe the default actions have changed since I set it up and a simple check box on that tab somewhere will make your work. If so, I will update the first post to reflect that.
My PTZ does not go back home after any specified time after moving it manually.
So now I am thinking
Blue Iris does indeed trigger and sends the preset during the initial trigger from spotter cam...but that's it. I bet it's now up to the PTZ to delay/idle timeout to go back HOME.
Digging through help file about break time I understand it a bit more and why there are two options in the "break time" window box of camera settings/trigger.
a.) end trigger unless re-triggered within: 10 seconds [variable time is set to your own liking]
b.) maximum trigger/alert duration: 60 seconds [variable time is set to your own liking]
Suppose you have a drunk naked guy doing just 1 jumping jack on your front lawn and it takes him 5 seconds. You will not have 5 seconds of recorded video but the entire triggered time of 15 seconds (Blue Iris resets trigger timer back to 0 for every re-trigger to start counting to 10 again ) , and only 1 alert image. How often/fast does it re-trigger while naked guy is hitting tripwires or motion? Unknown...I can only assume every second as a guess.
Suppose you have a drunk naked guy doing jumping jacks your front lawn for 4 minutes (240 seconds). Because he keeps initiating re-triggers, the max re-trigger possible is 60 seconds. Boom...a new trigger is started at 61 seconds. 2 more triggers. You will have 4 triggers and 4 alert images.
I do not think 'break time' has any bearing upon the PTZ going back home when idle, other than doing it's job when initially triggered and for how long the trigger lasts.
Just sharing some neat Blue Iris help info about break time as I never understood what it did til today
