Camera Profiles

Add camera classes (same settings grouped). Bitrate is estimated from resolution, fps, codec and scene complexity, then adjusted by duty cycle (hours/day or motion%).

Retention & Storage Parameters

Configure storage requirements and RAID settings for optimal data retention and redundancy.

Retention (days) required Typical range: 30-90 days

Filesystem Overhead (%) Recommended: 10-15%

RAID Level RAID5/6 recommended for reliability

RAID Group Disks Typical: 8-12 drives per group

NVR Split Mode Split by TB for storage-based planning

Max TB per NVR (usable) Check NVR model specifications

Advisory: Estimates use practical heuristics (e.g., 1080p@15fps H.264 ≈4 Mb/s; H.265 ≈2.6 Mb/s; 4K@15fps H.264 ≈12 Mb/s; H.265 ≈7.5 Mb/s) scaled with fps and scene factors (Low 0.6, Medium 1.0, High 1.6). Adjust to vendor bitrate tables as required.
