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:
In this example, 16 cameras recording continuously for 30 days require approximately 2.6 TB of storage. Therefore, a minimum recommended storage capacity of 3 TB is selected to allow for system overhead and future expansion.
Accurate storage calculation helps ensure reliable recording, proper retention, and smooth system operation without unexpected storage shortages.
