When photos/pictures are blurred, this generally is because the camera was moving or shaking when the photo was taken.
Turn on the OIS (Optical Image Stabilization) feature which enables the camera to compensate for unintentional movement when taking a photo.
You can also try using a tri-pod using the standard 1/4" screw in the bottom of the AZ252 to ensure the camera is steady when taking photos and videos.
Another option is to set the camera on a steady surface, which will help eliminate blurry photos and videos.
