Capture Mode. 

- Should the capture resolution match the encode resolution?

1. The capture resolution and encoding resolution are inconsistent.

- Is it expected for a capture to be 2MP/1080p when the camera is configured for 5MP?

2. Yes, the maximum resolution of TEBFDAIP5MP28-AI-L capture is 2MP.

- Does the resolution change based on the specific camera/nvr model? If so, could you share a table or documentation for reference?

3. The resolution of captured images varies depending on the camera model. Some camera models will have a different resolution stored on the NVR when connected to an NVR. We do not currently have complete documentation.I can help to find information for specific models if needed.
