Object Detection Troubleshooting

If your Scrypted NVR is having issues with Object Detection, perform the following tests to determine where it is broken. Then let koush know results on Discord's #nvr channel.

1. Verify Motion Sensor

You can check if motion events are being reported from the camera in the Events tab.

2. Verify Object Detector

Navigate to the appropriate Detector (CoreML on Mac, OpenVINO on Linux or Windows, etc), and save/drag this test image into to the detector:

The results should look similar to this:

Video

Navigate to a camera within the Management Console that has a person or car within view. Deselect Scrypted NVR Object Detection (if it is selected). Select CoreML/OpenVINO/TensorFlow, whatever was installed automatically.

Click Analyze.

3. Verify Scrypted NVR Object Detection

  1. Deselect the detector (CoreML/OpenVINO/TensorFlow).
  2. Select Scrypted NVR Object Detection (which was selected prior to the test).

This step is like the previous step, except the image and video detection tests are performed on the Scrypted NVR Object Detection. The NVR Object Detection will only show the red detection boxes when an object is actively moving in view.
