CCTV Storage Calculator: How Many Terabytes Do You Need for 30 Days of 4K IP Camera Footage in Kenya?

Avoiding Early Overwrite on Surveillance Footage

Kenyan insurance underwriters and security regulations often require commercial premises to retain high-definition CCTV recordings for at least 30 to 60 calendar days. Using modern Smart H.265+ video encoding reduces surveillance bitrates by up to 75% compared to legacy H.264 without compromising facial recognition or license plate clarity.

Storage Sizing Formula

A typical 16-camera 4K (8MP) system running at 15 FPS with H.265+ motion recording requires approximately 16TB to 24TB of dedicated surveillance storage (such as two 10TB or 12TB Western Digital Purple Pro drives) to guarantee a full 30-day retention window.
