CCTV architecture & storage

Switch data paths, inspect devices, and estimate decimal TB from bitrate and retention. The 20% uplift is planning headroom—not RAID purchase capacity.

SYSTEM OVERVIEW

CCTV surveillance architecture

Cameras capture and encode; switches carry traffic; NVRs record and play back; VMS integrates viewing, devices, and events when the project allows.

  • Separate front-end, network, and back-end roles
  • Distinguish NVR recording from VMS management
  • Confirm real platform and device compatibility

Integrated NVRs, small sites, or cloud designs may differ from this schematic.
