> You have 10 cameras recording footage 24/7 at 30 FPS, 1920x1080 resolution. They’re all configured to send video clips back to the cloud in 10-minute intervals. A standard compression setup results in ~1 TB of video stored per day or 27 million individual frames .
Incorrect, I generate about 130MB files for 10 minutes segments on a camera of exactly those specs. Given that there are 1440 minutes in a day, that results in about 19 GB of data per day. The author assumes that there is always a unique frame but that's not true.
It depends on how much movement there is in the frame and the GOP interval.
H264 compression will not generate new frames if nothing has changed. There is an interval called the GOP interval which enforces that say every 2 seconds a keyframe is sent, meaning a complete raw frame is sent. This is to ensure that new viewers can catch on waiting max the GOP interval.
