The V403R11 firmware manages the hardware decoding of two primary video compression algorithms. Understanding how the firmware handles these codecs is essential for maximizing storage space and network bandwidth. H.264 (AVC) Support H.265 (HEVC) Support High; requires more data to transmit HD video. Low; reduces bandwidth needs by up to 50%. Storage Efficiency Standard; files take up significant hard drive space. High; doubles the recording history on the same HDD. Firmware Processing Low CPU overhead; highly compatible with older IP cameras.
