Storage Planning Tips

Use H.265 Compression

H.265 (HEVC) reduces storage requirements by up to 50% compared to H.264 with the same image quality. Always choose H.265-compatible cameras and NVR for new installations.

Enable Motion Detection Recording

For low-traffic areas, motion-triggered recording can reduce storage consumption by 50-70%. Combine with continuous recording for critical zones to balance coverage and cost.

Plan for 20% Overhead

Always add 20-30% buffer to your calculated storage. This accounts for higher-than-expected activity, system metadata, and future camera additions without requiring immediate hardware upgrades.

Consider RAID for Reliability

RAID 5 provides a good balance of capacity and redundancy for most installations. RAID 6 is recommended for mission-critical systems where data loss is unacceptable.

Tiered Storage Strategy

Use high-speed SSD for recent footage (7-14 days) and cost-effective HDD or cloud storage for long-term archiving. This optimizes both performance and cost.

Retention Period Requirements

Standard commercial: 30 days. Regulated industries (banking, healthcare): 90-365 days. Check local regulations for your specific industry and jurisdiction before finalizing storage capacity.
