The maximum storage capacity of a high-speed camera depends on the model and specifications of the camera. Some high-speed cameras have internal storage capabilities ranging from a few gigabytes to several terabytes. Additionally, high-speed cameras often have the ability to connect to external storage devices such as hard drives or network-attached storage (NAS) systems to further expand the storage capacity. Overall, the maximum storage capacity of a high-speed camera can vary greatly depending on the specific camera and its configuration.
