Move PTZ to presets based on specific triggered IVS rules of another camera

[yrt0098]

Apologies if I am missing it, but I can't seem to find info on how to set this up and am not sure if it's currently possible. I'm hoping someone here might know more and have some info on how to configure this:

My BI setup includes a 180-degree cam and a PTZ cam mounted near each other and normally facing the same direction. But because of the narrower FOV of the PTZ, the 180-degree sometimes picks up motion that never enters the PTZ's FOV. The 180-degree cam is set up with some IVS rules. I would like to configure the cameras such that the PTZ cam moves to presets based on the specific IVS rules triggered on the 180-dgree cam. This way the single 180-degree cam can direct the PTZ on where to look, with each IVS rule breaking the 180-degree FOV into smaller pieces that each act like a spotter cam.

As I understand, this can be achieved by cloning the 180-degree cam, but I would prefer to do it using the IVS rules if possible.

The latest I can find on the topic is below (maybe I'm searching the wrong terminology), but it seems this functionality wasn't yet possible as of mid-2023:

That is correct. But hopefully soon BI will be able to allow us to set up trigger based on which IVS rule is triggered

Is what I'm looking to do currently possible? Any tips on how to get this working (or to save me the frustration trying if it's a dead end haha) would be greatly appreciated. Thanks in advance!

You are in the wrong thread as I am doing exactly that once it became available in mid-2024 and updated the previous spotter thread. Go down about halfway on the 1st post with the edit:

Thread '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'

Mar 12, 2022

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 spotter cam #2 is triggered, it would then take the PTZ off of spotter cam #1 tracking and move to the preset for spotter cam #2.

Now with BI 5.5.6.0, you can go into the PTZ tab in the Camera setttings and go to the preset that you want to have priority and check the "cancel alerts when the camera is...

Here is the part from the above thread:

EDIT:
BI version 5.8.5.6 has added a lot more flexibility and getting us very close to this goal. Actually I think it is probably as close as it can get unless BI sets up a section just for Dahua IVS cams.

Before this version it still didn't do what I wanted (wouldn't allow me to have a camera trigger for BI motion and then allow me to alert based on different IVS rules and wouldn't allow it to trigger different functions based on which IVS rule was triggered) without the use of clones, which can get messy and complicated and remembering what does what later.

It is now possible!!!!

With my 180 camera I was able to set up different IVS rules and have it send the PTZ to all these different areas.

So I can set up a zone one one side of the street with a PTZ preset zoomed in tighter to that side of the road and a zone on my side of the street with a PTZ preset zoomed in tighter to this side of the road instead of my before just generally more wide PTZ preset to get either side of the road.

Takes a little bit of work and isn't plug-n-play, but wow is it a game changer.

Here is how it is done.

Under the ONVIF Triggers comes up all of the camera events it listens to. Each one corresponds to something in the camera - motion detection, SMD, IVS tripwire, IVS intrusion, etc.

There is no need to figure out which is what if you are using IVS rules, so you can turn all of those off.

Instead, either keep track of what each IVS rule is named (IVS-1, IVS-2, etc.) or rename each rule in the camera GUI.

Then simply hit the + sign and in the Contains block put in the name of the IVS rule (IVS-1 or if you renamed it something else) and then in the memo you put down what it is for.

As they populate, they will show up in the Listen for:

Then you go into the alerts tab and the stuff you put in the Memo field can be used for the required AI:

Then you go to the spotter camera in BI and go to the Alerts tab and select one of the bottom two depending on your use case.

Use the "New zones/sources only (additive)" option if you are going to have several IVS rules being used in one camera and want to be able to do something with each rule separately.

The "New zones/sources only (exclusive)" option is a cool feature if you want to primarily use IVS rules for triggering your alerts, but you want to use BI motion to capture wildlife and other things. Prior to this option, you would need to use a clone because if the motion triggered first, then the IVS wouldn't trigger. Now you can use one camera and this trigger option and the object can trigger BI motion first and if it then triggers IVS, it will alert you of the IVS trigger.

Everything above "Then you go to the spotter camera in BI..." is done in the fixed spotter cameras. The events to listen for are done in the fixed camera not the PTZ.



And then in BI for the PTZ, under Alerts is where you tell it what to do whenever the spotter cam is triggered.

Use the "New zones/sources only (additive)" option if you are going to have several IVS rules being used in one camera and want to be able to do something with each rule separately.

Edit: Disregard, you answered above, thanks!


Thanks! Great to hear this is possible! I will start experimenting with it.

To ensure I'm understanding, are all of the edits above for on the 180-degree/spotter cam only (and no changes detailed above are for the PTZ)?

So the spotter does all of the listening for its own IVS rules to be triggered and then once it sees the alert, it sends a command to the PTZ to move accordingly?

 

[wittaj]

That is correct. So say you have 3 IVS rules in the 180 to correspond to 3 different PTZ presets, you would have 3 of these in the Alerts section of the spotter/fixed cam - one for each IVS rule and which PTZ preset to move to:

It's now working, thanks for the help!
