Hi,

Does anyone know how to change the image size resolution or perhaps HTTP API to snap lower image size?
My Dahua version is IPC-HFW2431T-ZAS-S2 using firmware V2.820.0000000.45.R, Build Date: 2022-03-31

I have tried to change the video resolution and also enable the sub stream, but the snapshot image size still the same.

Thank you for your help

If I change the video resolution of the main stream, the Snapshot Image Size changes with it (HDW5442TM-AS):

As commented on this thread, the image quality from grabbing an image from snapshot.cgi is MUCH less than if you do a do a Snapshot from the Live view using the camera icon. Any ideas on how to improve the quality? I've tried adding some misc. parameters to /cgi-bin/snapshot.cgi, but doesn't seem to make any difference.

This is on a recently purchased IPC-T54IR-ZE-S3 (with 2023-11-27 firmware applied) - the Snapshot menu is no longer in Camera, but now under Pictures - didn't seem to make a difference.
