CCTV storage capacity is not a random selection. It must be meticulously calculated based on key technical factors:
📹 Number of cameras
🎥 Resolution & Frame Rate (FPS)
💾 Bitrate (H.265/H.264)
⏱️ Recording Mode (Continuous vs. Motion)
📅 Required Retention Period

Example from our Project Engineering team:
16 cameras recording continuously for 30 days require approximately \(2.6 \text{ TB}\) of storage. To ensure system overhead, future expansion, and proper system operation, we recommend a minimum of \(3 \text{ TB}\) of storage.

Accurate storage calculation helps avoid unexpected shortages and ensures your surveillance system remains functional, compliant, and efficient.
