Crashes with one camera, but not the other

[pjpjuk]

I've got a couple of HikVision cameras and when I test the motion detection on one of the cameras (Gate) it seems fine, saves the image to the capture folder and it there is detected object does it's magic. The problem is that my other camera (Driveway) crashes SynoAI. The only difference between the cameras is that one is an 8K and the other a 5K camera. I can force the crash by running the test action rule.

Below is the config file and the error:

Is there anything else in the logs? There's no actual error there.

Thanks!! This was just a dummy configuration - removing it and replacing it with a pushover notifier. This is working really well - thanks for all the hard-work!

Two questions:

1. Is it possible to run without a notifier - It seems to crash upon start-up if the notifier section is empty?
2. I can't quite get the syntax right for specifying which camera uses a specific notifier. Could you provide an example for using pushover to send a notification for 2 cameras but not a third? I didn't quite understand the syntax in the readme:

"Notifiers": [
{
"Type": "{Type}",
"Cameras": [ "Driveway", "Garden"]
}
]

[djdd87]

It shouldn't crash, it should gracefully exit - there's a difference. The app intentionally stops when there's no notifications, because without the notifications the app is pretty pointless isn't it? Make sure you're on the latest version if it's throwing an exception and exiting.

What would you expect to happen with no notifiers out of interest? It'd just sit there silently saving images that you'd have to go and check manually.

Like this:

  "Notifiers": [
    {
      "Type": "Pushbullet",
      "ApiKey": "abc123",
      "Cameras": [ "Camera1", "Camera2" ]
    }
  ],

[pjpjuk]

Exit with grace is fine - I wasn't aware it was doing this. I only downloaded it yesterday through the Synology docker interface so presume it was the latest version, but I'll double check.

I don't mind it sitting in the background recording images. It was more to know if anyone was walking around the house at night without having to sift through the video footage and false motion detections. I guess in the future once I narrow down the settings I'll set-up a notification, hence the reason why I set-up a temporary pushbullet and then everything was working fine again.

Out of curiosity, if I leave the "Cameras" variable empty or use a dummy name, it will still run but not send the notification?

[djdd87]

Cool, you should definitely be on the latest version then!

Unfortunately you will need to have at least one notification currently, because that's just the way it's designed. It's certainly something I can add later, but it kind of goes against the point of the project.

If you leave the "Cameras" property blank, then it'll run that notification for all cameras.

Cameras [optional]: A list of camera names that the notification will be triggered for. Allows certain notifications to only trigger for specific cameras; not specifying the value, or setting cameras to an empty array, will result in the notification being sent for all cameras.

I'm planning on reversing this in the future so that you specify which notifications to run on a camera by camera basis instead of defining the cameras for the notifications.

[pjpjuk]

That's ok..I'll work with what is there which is more than enough! Looking forward to any future development of the project.
