▮ Question
Is the JPEG image obtained by the API camera Thumbnail exactly the same as the setting conditions?

In other words, if the recording setting is 4K, will the API extract with the same 4K resolution, the same image size, and the same compression ratio?

▮ Recording setting information
Primary, MJPEG, 30fps, 4K

  Hello Kai,

  In other words, if the recording setting is 4K, will the API extract with the same 4K resolution, the same image size, and the same compression ratio?

  the resolution will be the same unless you specify custom parameters in the API request. By the same, I mean same as the resolution of the archived video. For example, if you don't have recording enabled for the primary stream all the time, API might return image from the secondary stream. As for the compression ratio, API doesn't attempt to compress source image, it packs it to JPEG "as is", so it should be relatively close to the original image.

  Thank you for the fast reply!
  I understand that the resolution does not change.

  You can now close it. Thank you so much.
