When changing resolution of fisheye camera from unsupported resolution to supported resolution, it pops up alert message saying “EXCEEDS THE MAXIMUM RESOLUTION OF NVR. (MAX:3840 x 2160)”.

When changing resolution from supported one to unsupported one, it does not pop up message.

It works in reverse.

But, this only happened in one of two cameras of the same model in the test.

*After alert, changed resolution is applied.
