Frigate Snapshots vs. HA Integration Snapshots

[AdmiralRaccoon]

Hello,
I wonder if this is a config error of mine? I´m using the HA Integration, and have a Dashboard with picture entities of the latest Snapshots.

Now this is a Snapshot from the HA Dashboard:

And this is from the Frigate UI from the same person / time:

On the HA Snapshot I can only see the legs of the person, while the Frigate UI shows me the entire person standing at the door, and this is what I would like to see on the HA Dashboard as well.

This is the config for the affected camera, thank you very much in advance for any hints.
Have a nice day,
Philipp

The difference you're seeing is due to how snapshots are published via MQTT versus what's stored in Frigate's UI.

When Home Assistant receives snapshots through MQTT, it gets them from the frigate/<camera_name>/<object_name>/snapshot topic(1). According to the MQTT documentation, this topic "publishes a jpeg encoded frame of the detected object type" and "when the object is no longer detected, the highest confidence image is published"(1).

The key issue is that your snapshot configuration has crop: false(2), but the MQTT snapshot topic appears to be publishing a cropped view focused on the detected object's bounding box during tracking, which is why you're only seeing the legs in Home Assistant.

The Frigate UI shows the full snapshot with the complete person because it displays the stored snapshot image that respects your crop: false setting(2).

To get the full uncropped snapshot in Home Assistant, you have a few options:

1. Use the snapshot entity directly from the Frigate integration rather than relying on the MQTT snapshot topic - the integration should provide access to the actual stored snapshots

2. Keep crop: false in your snapshots configuration (which you already have)(2)

3. Verify your Home Assistant picture entity is pulling from the correct source - it should reference the Frigate snapshot storage path or use the Frigate integration's snapshot entity, not the MQTT topic

The snapshot configuration you have should work correctly:

snapshots:
  enabled: true
  timestamp: true
  bounding_box: true
  crop: false

(2)

This configuration will save uncropped snapshots with timestamps and bounding boxes(2), which is what you're seeing in the Frigate UI.
