The short answer
Before you share anything, copy the original video to a safe place and never edit it. Recipients split into two groups: police and insurers usually need the unmodified original plus a short incident summary, while the media and the public should only ever receive a version with faces, number plates and other identifiers blurred. Transfer large files through secure channels, keep a simple chain-of-custody note, and confirm receipt in writing.
Key takeaways
- Police and insurers generally want the original, unedited file; editing, converting or re-compressing raises doubts about authenticity and can slow a claim or investigation.
- Copy and lock the clip before anything else — loop recording can overwrite the incident within minutes to hours.
- Faces, number plates and other identifiers make footage personal data, so blur them before public or media sharing and keep audio recording off by default.
- Provide context with the video: date, time, exact location, direction of travel, vehicles involved, and disclose a wrong device clock.
- Keep a simple chain-of-custody record of who handled the file and when, and confirm receipt in writing after every transfer.
- Treat officials and the public as separate audiences with separate versions of the same clip.
Secure the original before you send anything
Start by protecting the file, not by sending it. Dashcams, doorbell cameras and many phones use looping or rolling storage, so the clip of an incident can be overwritten within minutes to hours. If your camera has a lock button (often a small key or red-dot icon), press it right away; otherwise open the companion app and save the event, or stop recording and copy the card before anything can be overwritten. Keep the card labelled with the date and time in a safe place.
Keep the original untouched. Do not edit, trim, compress, convert or re-export the master file: reformatting changes metadata and invites questions about authenticity that can slow a claim or investigation. If you need to trim or annotate footage for your own review, make a copy first and work only from that copy. The file you hand over should be the same bytes that came off the camera or recorder.
Police and insurers: they want the untouched file plus context
For a crash claim or a witness report, the unmodified original carries the weight. Adjusters and investigators look for the sequence of events, timestamps, GPS data and clear images of vehicles and registration plates. Prepare a short cover summary with the date, time, exact location, direction of travel and the vehicles involved. If the camera clock is wrong, say so on the form rather than letting an incorrect timestamp raise doubts later.
Offer the original file and, only if asked, a trimmed version. Keep the whole clip safe in case an investigator needs the wider context, including what happened in the minute before and after the incident. Many police forces run online portals where you upload the clip with a witness statement; insurers usually accept uploads in their claims portal, over a secure link or on a labelled drive at a branch. Confirm the accepted channel before emailing very large files.

Know the privacy split between officials and the public
Under the UK GDPR and similar regimes, footage becomes personal data whenever an identifiable person is visible — a readable face or number plate is enough. Sharing it with the police or an insurer in connection with a legitimate claim or report is generally acceptable and does not require you to blur identifiers first; the footage loses value if you obscure the very things investigators need.
The rules tighten once footage moves toward the media or the public. Publishing identifiable people without good reason can be a data protection breach. The practical habit is to treat officials and the public as two separate audiences: prepare an original version for police and insurers, and a separately rendered, blurred version for media, community groups or social media. Where audio is recorded, keep it switched off by default and use it only where clearly justified, because conversations capture far more sensitive data than images alone.
Get the file across reliably and record the handover
Large video files rarely fit in email. Use the recipient's preferred secure channel — a claims portal, an encrypted file share or an official police upload form — and avoid messaging apps that compress video or open public links that let anyone with the address view the clip. Common formats such as MP4 and MOV are widely accepted; do not convert the file purely to shrink it, because re-encoding strips metadata and can raise authenticity questions.
Keep a simple chain-of-custody note: who created the file, who handled it and when, and how it was transferred to each recipient. After you upload, confirm in writing that the file opened correctly, that timestamps and GPS data are visible, and that a copy has been received. These notes matter if the footage is later disputed in a claim, an employment matter or court proceedings.
If it goes to media: redact, add context, protect people
Eyewitness and camera footage can be genuinely valuable to journalists, but publishing it is a different decision from handing it to officials. Redact faces, number plates, house numbers, screens, tattoos and anything else that lets a viewer identify a bystander, victim or suspect who is not part of your purpose. Avoid making any individual the main object of the frame when that is not needed for the story.
Give the outlet context: what the camera was, when and where the clip was recorded, and whether it is the original or an edited excerpt, so it is not misrepresented. Where consent is possible, obtain it before using footage that centres on a person. These are general ethical and data-protection principles, not legal advice for a specific country or case; check local rules and seek professional guidance for sensitive or high-stakes footage.
Put it into practice
Pre-share checklist for a video you intend to hand over
Run every clip through this list before you send it to an insurer, the police or the media. It protects both the authenticity of your evidence and other people's privacy.
- I copied the original to a separate, safe location and did not edit it.
- The relevant clip is locked or protected from overwriting; the storage is labelled with the date and time.
- I decided the recipient and prepared the right version for them (original vs blurred).
- For a crash claim, I captured damage, both vehicles' positions and registrations, and context landmarks before anything moved.
- I prepared a cover summary with date, time, exact location, direction of travel and vehicles involved.
- I checked the device clock and will disclose any wrong timestamp.
- For police or insurers, I will send the unmodified original and keep a trimmed version only as a supplement.
- For media or public sharing, I blurred faces, number plates and other identifiers.
- I will send the file over a secure, documented channel (portal, encrypted share, official form) — not an open public link.
- I will confirm receipt in writing and note who, when and how the file was transferred.
Questions people ask
Do I need to blur faces and number plates before sending footage to the police or insurer?
Generally no. For a legitimate claim or witness report, the police and insurer need the readable identifiers — faces, plates, vehicles — and blurring them destroys the evidentiary value. Under the UK GDPR this sharing is usually acceptable as part of handling a claim or crime report. Blurring becomes important when the same footage is going to the media, the public or social media, where identifiable people should be protected.
How long do I have to submit dashcam footage to the police or my insurer?
It varies. Insurers generally expect footage as soon as possible after a claim is opened, and many ask for it within days. Police witness-reporting portals (such as UK Operation Snap schemes) typically require submission within about seven days of the incident, though this differs by force. The safest approach is to secure the clip immediately and check the relevant insurer or force guidance for the exact deadline so footage is not lost or rejected as late.
Is it a problem if I only kept a trimmed or compressed copy?
Potentially. Trimming, re-compressing or converting a file changes its metadata and raises questions about whether the sequence has been altered or important frames omitted. That is why the original is preferred. If only an edited copy remains, disclose it honestly and explain what you changed, so investigators can judge its reliability instead of discovering the discrepancy later.
Could my own footage be used against me?
Yes. A video records facts and is not guaranteed to help your side. If your insurer asks for footage you have disclosed or that you claim to have, withholding or deleting it can breach your policy terms or look like concealment. Submit the original file and keep a copy until the claim or investigation is fully closed, even if the footage is unfavourable to you.
What counts as personal data in my video?
Under the UK GDPR and similar laws, video contains personal data whenever an identifiable individual is visible — a clearly readable face or number plate is enough. Even without a clear face, recognisable context such as a uniform, a distinctive car or a house can make a person identifiable. Treat such footage as personal data: keep it secure, share it only with those who need it, delete it when the purpose ends, and blur identifiers before any public or media use.
