With more people looking to get a PTZ and asking about it moving to a preset and auto-tracking I decided to put a video together. This shows how the PTZ goes from parked to a preset based on an IVS trigger from a spotter camera. From this preset the PTZ has its own IVS rules to tell it to auto-track.
Hardware:
PTZ: SD4A425DB-HNY
Spotter: HFW5241E-Z12E
VMS: Blue Iris
How it happens:
The spotter is using IVS rules with trip wires. They are one way A > B and Person detection.
If a person is detected, and they break the trip wire, an ONVIF trigger is sent to Blue Iris.
The spotter camera's Trigger tab is set to both trigger my PTZ camera group and move it to the specified preset.
Once the PTZ arrives at the preset its own IVS rules take over. They are set for one way A > B and Person detection with tracking.
If a person is detected moving across the IVS trip wire from A > B then the PTZ will start tracking them.
All of the triggers and timing may not be synced perfectly, but it's pretty darn close. Also, do not judge the video quality as it is a product of how I had to gather the clips to include the IVS rules.
For reference, this is the relation of the spotter cam's FOV to the PTZ's call-to location. Ideally I will get a spotter trigger as soon as someone crosses into the red FOV.
Pink is parked.
Yellow is call-to.
Red is spotter.

Using Spotter Cameras to direct a PTZ where to look in an NVR or Blue Iris and setting a spotter cam as a priority in Blue Iris
We get this question from time to time, so I thought with the recent addition to BI, it made sense to have a thread we can point to. Previously in BI, if you had more than one spotter cam, you could not make one a priority, so if spotter cam #1 triggered the PTZ and it starts tracking and...
