The duration of recording storage on a DAHUA CCTV system depends on factors such as hard drive capacity, recording resolution, frame rate, and video compression settings. DAHUA systems are compatible with large-capacity NVRs and DVRs, and many models support up to 10TB or more of storage per drive bay. Using Smart H.265+ compression technology, DAHUA can significantly reduce the file size of recordings, effectively extending storage duration while maintaining image quality. With a high-capacity hard drive and appropriate compression settings, users can store recordings for weeks or even months. Additionally, DAHUA systems support external storage options like network-attached storage (NAS) and can be configured to backup footage for redundancy, ensuring secure long-term storage.
