Why H.264 matters : The codec balances compression and computational load. On the Cortex‑A53, each stream consumes ~150 MHz of CPU; eight streams comfortably stay under 80 % CPU utilization, leaving headroom for analytics.
Advanced IPVR units, such as those in the enterprise class, can support hundreds of camera inputs and petabytes of storage. 2. The Role of H.264 (264) in Modern IP Systems ipvr-264
