The substitution of a high-capacity external HDD (up to 1TB) in lieu of a USB memory enables the potential for protracted recording periods.
As a noteworthy consideration, externally powered HDDs are imperative, as those reliant on bus power will not function. It is essential to employ self-powered HDDs, ensuring an independent power supply for the external HDD.
Furthermore, if the formatting adheres to FAT32, there exists a file size limitation of 4GB. Therefore, for individuals aspiring to record lengthy videos within a single file, employing an HDD formatted with NTFS is recommended.
It is crucial to note that operation is not supported with exFAT formatting.
