IP security camera recording to a NVR (Network Video Recorder). H.264 for hardware decoder support on cheap NVR chips, CBR 2M for predictable storage planning, MPEG-TS for crash resilience — if power cuts, only the last packet is lost.

A 32-camera NVR at this bitrate fills a 16 TB drive in about 24 days, which is why most surveillance systems use motion-triggered variable bitrate to extend storage 3-5x.
