Do AV panoramic cameras have a "stitching" mode to produce the panoramic view?
No. AV panoramic cameras do not have a "stitching" mode. However, each panoramic camera produces four separate video streams, one from each sensor. You can create the panoramic view by lining the images from each of the camera's sensors up side-by-side in the camera's web interface or using your VMS/NVR software.
