PADD recorders. We convert these exports to standard MP4 with a browser-based player, without re-encoding the recorded video.
The container's timing does not always agree with the recorder's clock, which matters when the question is what happened at a particular moment.
The usual result is that the footage exists, is perfectly good, and cannot be watched by the person who needs to watch it — because the only software that opens it is the manufacturer's own, it is Windows-only, and the machine it needs to run on is locked down.
Extensions get reused and renamed, so the reliable test is the first few bytes of the file. On any machine, without installing anything:
xxd -s 0 -l 16 "your-file.sec" # macOS / Linux
certutil -dump "your-file.sec" # WindowsA PADD export begins 00 E0 00 03 — PADD's record marker.
The window in the filename is the recorder's local time, so it is used as-is rather than shifted — and it is checked against the recorder's own clock rather than trusted.
The container's timing does not always agree with the recorder's clock, which matters precisely when the question is what happened at a given moment.
The window in the filename and the recorder's own clock are checked against each other rather than one being assumed correct — the two conventions differ between vendors and cannot share a code path.
Read by own parser. ffmpeg cannot open this container at all, which is why the ordinary tools a customer already has produce nothing from it. We read it ourselves. The source-side integrity digest is therefore taken from the extracted stream, since that is the only point at which the original picture data can be measured.
Timing is verified against the recorder's own clock rather than taken on trust from the container.
The coded video itself is copied, never re-encoded. That is the point: what you receive is the recorded image, not a compressed copy of it.
One standard MP4 per camera, a browser player with every camera on a shared timeline, and a certificate digesting the coded picture data before and after — which match, because the video is copied rather than re-encoded. What every conversion includes → · How the check works →

PADD recorders. The container's timing does not always agree with the recorder's clock, which matters when the question is what happened at a particular moment.
Because it is a proprietary PADD format. General-purpose players such as VLC, Windows Media Player and QuickTime are not built to read it and usually show nothing or refuse the file. In practice: The container's timing does not always agree with the recorder's clock, which matters precisely when the question is what happened at a given moment.
As it stands, .sec opens only in PADD's own player, which is Windows-only and often has to run on a locked-down machine. The dependable way to open it anywhere — any operating system, no install — is to convert it to MP4, which is what we do. The recorded video is copied, not re-encoded, so what you watch is the recorded image itself.
Send us the .sec export — ideally the whole folder as the recorder wrote it. We convert it to standard MP4, one file per camera, with a browser player and a certificate that digests the coded picture before and after so the result can be verified independently. The first conversion is free. If it turns out not to convert, we may ask for the player it shipped with so we can make it work.
