Surveillance storage calculator
Configure camera groups and storage redundancy to estimate recording capacity.
Camera groups
Group 1
Preset bitrate is a planning assumption; FPS scales it proportionally.
Retention and headroom
RAID and storage configuration
Drive sizing fields power the reverse retention estimate; raw capacity uses bays less hot spares.
Storage estimate
Required usable capacity
—
TB decimal
Binary capacity— TiB
Incoming bandwidth— Mbps
Raw required capacity— TB
Configured usable capacity— TB
Bandwidth exceeds the selected common NVR limit. Confirm the recorder's sustained incoming bandwidth rating.
Reverse retention for target drives— days
Daily recording breakdown
Estimates only. Actual bitrates vary by camera model, scene complexity and lighting conditions. Motion buffer is modelled as a practical activity uplift based on the fixed pre/post seconds per expected event.
