MiBeeNvr Author Explains the Storage Design of Adaptive Recording

The MiBeeNvr author explains the adaptive recording mechanism: it determines scene activity by measuring P-frame sizes, without decoding or running AI models, and measured disk usage in static scenes drops by about 75%–98%. When activity is detected, it first uses a 32MB GOP pre-buffer to backfill the frames before the spike and then switches back to full frame rate, achieving zero frame loss during switching; for cameras whose bitrate has been flattened, it falls back to pixgate pixel-domain gating and tiered recording.
