Storage & Retention Estimator
Quick planning math real-world results vary by codec, FPS, VBR behavior, and scene motion.
Estimate per-camera daily storage, total daily load, and retention storage from bitrate + recording mode. Add overhead reserve to stay conservative against VBR spikes and real-world variance.
