It simultaneously records from up to 64 IP cameras, providing centralized video management, storage, and playback for comprehensive security monitoring.\u003c\/p\u003e\n\u003ch3\u003eHow much video can the NVR508-E-R store?\u003c\/h3\u003e\n\u003cp\u003eWith 8 SATA HDD bays supporting up to 16TB drives each, the NVR508-E-R can store up to 128TB of video. Actual storage duration depends on resolution, frame rate, and codec compression. Ultra 265\/H.265 encoding maximizes storage efficiency compared to H.264.\u003c\/p\u003e\n\u003ch3\u003eWhat does N+1 hot spare mean on this NVR?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eN+1 redundancy\u003c\/strong\u003e means one additional hard drive is configured as a backup.
