Compare H.264 and H.265 (HEVC) video compression codecs for IP security cameras — covering storage savings, bandwidth requirements, hardware compatibility, and when to use each in a CCTV system design.
The video codec determines how much storage and network bandwidth your surveillance system requires. For a 32-camera system recording 24/7 at 4MP resolution, choosing H.265 over H.264 can reduce storage requirements by 40–50% — potentially saving thousands of dollars in NVR storage costs while maintaining the same image quality. For large enterprise systems, codec selection is one of the most impactful design decisions.
