H.265 IP Cameras Tested vs H.264

Author: Ethan Ace, Published on Jan 18, 2016

For more than 2 years, anticipation has been building for H.265 IP cameras. Finally, H.265 cameras are starting to ship from multiple manufacturers in North America.

The promise is ~50% bandwidth reduction which, if true, would be a huge saver for storage costs as well as making remote monitoring easier and large scale VSaaS more feasible. In the mean time, 'smart codecs' for H.264, have come out, which also offer significant bandwidth savings (e.g., see our Axis Zipstream test).

We tested H.265 cameras from Samsung and Vivotek to understand:

  • Bandwidth tradeoff / savings compared to current H.264 camera models widely used (e.g., IP Camera Bandwidth / Storage Shootout).
  • CPU Load tradeoffs vs H.264 for viewing
  • VMS support for H.265
  • Finally, H.265 vs Smart Codecs such as Axis Zipstream

We performed both technical stream analysis and image quality comparisons to understand quality and bandwidth tradeoffs.
