Storage Guide – Choosing the Right Hard Drive

The amount of storage you need depends on the number of cameras, camera resolution, recording schedule, and how long you want to keep your footage.

Quick Reference

Suggested starting capacities for typical CCTV systems:

Choose a larger drive when recording continuously, using high-resolution cameras, or keeping footage for longer periods.

Consider More Storage If You:

• Record continuously, 24 hours a day
• Use 4MP, 6MP, or 8MP/4K cameras
• Need to retain footage for 30 days or longer
• Have busy areas with frequent movement
• Record audio together with video
• Plan to add more cameras later
