Lay one capture out as an A4 evidence pack with its frames, readings and seal, ready to print or save as a PDF.
One capture, on A4
On any capture, select Evidence pack.
Frames and the measurement
Every key frame with its time, then the radar speed, the limit and the verdict.
Each source with its provenance
Drive unit and AIS readings are listed with where they came from. They are not part of the capture seal.
Checkable later
The record hash, the hash it chains to, and a code to scan that leads back to this capture.
Print or save as PDF
The button waits until every frame has loaded, so a printed pack never has blanks.
Open the capture you need to stand behind, then select Evidence pack. The pack is laid out as an A4 page, so what you see is what prints.
Every key frame is printed with its time into the pass, and the key frame shows the boxes. Under them sit the measurement: the radar speed, the limit, how far over, and who set the verdict.
Corroborating readings lists the other sources at that moment, each with its own provenance. The drive unit reading was sealed at source; AIS is a public feed. Where there is a drive reading, its own proof is printed below.
The seal section prints the record hash and the one it is chained to, with a code you can scan that leads back to this capture. Anyone holding the paper can check it against the record later.
When every frame has loaded, select Print or save as PDF and choose a printer or Save as PDF. The link at the top left takes you back to the capture.
