You can do it within Blue Iris since you already have it - you do not need to go purchase an NVR for this.
With Blue Iris, you can use any camera as a spotter camera, and those are fine cameras for it.
Just set up the triggers to trigger the other cam. Not hard to do in BI.
On the fixed camera, set up a group containing the camera to move when that cam triggers - it should be the only camera in the group so call it PTZ1 for example.
In the camera GUI for the PTZ, make a preset for it to move to when triggered which gives the view you want.
On the Trigger tab for the fixed camera, under "When triggered" select "Move to preset" and select the preset you just created for the PTZ.
Go back to the Trigger tab and key it in under the When Triggered area. This should be your fixed camera tabs not the PTZ tabs.
Check the Trigger camera group and hit select and pick the group name the PTZ is in.
Then check the Move to preset and change the number to the preset on the PTZ you want it to move to.
Then check the move camera groups and hit select and then the camera group.
Hit ok and then that fixed cam will call up the PTZ whenever the fixed cam sees motion.
Then when something triggers the fixed came, it will move the PTZ to the assigned preset. You can use the "Trigger Now" to test.
The "Break time" on the trigger tab controls how long the moved camera stay on the preset before moving back to where they were. To get the camera back you could use that based on some time. I think a setting of 0 turns that off.
Thanks for the walkthrough! Looking forward to testing this out with BI in the future.
