How much CCTV footage can it store?
The storage duration depends on the number of cameras, their resolution, recording settings and video compression.

For example, with eight cameras recording continuously at an illustrative bitrate of 2 Mbps per camera, 6TB could store roughly 35 days of footage before accounting for overhead and other system requirements.
