ffprobe on this web-app server — the same thing VLC or a VMS does.
Pre-roll adds footage before the start; post-roll after the stop. Leave blank for Edge defaults, or set both to 0 for only the recording interval. Active recordings keep their original settings; cuts follow camera keyframes.
Dates are sent as UTC and clips appear newest first. The reference is also attached to new recordings. Continuous history needs the recordings permission and an Edge recording buffer. Titles accept {camera}, {timestamp} and {ref}.
