Dashcam footage preservation checklist: keep the original clip and date its exact bytes.

Dashcam footage preservation checklist: keep the original clip and date its exact bytes. Keep your original source records together, then date the exact files. It does not establish the recording time, complete coverage, an unedited history before receipt, identity, fault or admissibility.

Now keep it safe: three things
  1. Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
  2. Save this receipt to your camera roll.

    Keep the receipt file too. The image is a handy copy; checking needs the file.

  3. Email it to yourself.Email it to myself

    Your mail app opens a draft. Attach your receipt image and receipt file. Don’t attach your photos or documents. Timevolt does not send it or know whether it was sent.

      How to keep notes that hold up

      Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.

      1. Write it down straight away, on paper or in the box on a step.
      2. Put the date, time and place at the top, and who you spoke to.
      3. Use their words where you can; separate what you saw from what you were told.
      4. Sign or initial a paper note, photograph it and add the photo.
      5. Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

      Missing video does not prove it would help

      An arrested person said missing dashcam video would back a claim of too much force. The appeal court assumed the video was lost but found no proof the loss hurt the case or was intended. It refused penalties and kept the earlier court's ruling.

      Routine dashcam footage may have to be shared

      A freight firm withheld video of its driver after a crash, calling it private work for a court case. The court ordered it shared because it was routine footage. It noted possible loss of a longer clip but did not decide a penalty for that.

      Review each part before withholding dashcam footage

      A public body withheld recordings during an inquiry, then released them while the case was pending. The top state court said only a short stretch of questioning could be kept private. It refused fees, costs and payment for harm.

      Proves / Doesn’t prove

      Proves

      A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.

      Doesn’t prove

      It does not establish the recording time, complete coverage, an unedited history before receipt, identity, fault or admissibility.

      It does not establish the recording time, complete coverage, an unedited history before receipt, identity, fault or admissibility.

      These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.

      Questions, answered plainly.

      Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.

      Does a receipt save the video?

      No. Save and back up the original recording separately; the receipt only dates its fingerprint.
