Object Detection Troubleshooting

Koushik Dutta edited this page Jun 24, 2023 · 13 revisions

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.

0. Rerun Installer

If this is a local (not Docker) installation, rerun the install script.

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.

Verify the video detection highlights the car or person with a red box.

3. Verify Scrypted NVR Object Detection

This is like the previous step, except the image and video detection tests are performed on the Scrypted NVR Object Detection (this can be located within the NVR plugin). The red detection boxes will only be shown when an object is actively moving in view.

After this step, Scrypted NVR Object Detection should once again be enabled on the camera.
