You step out of your car after the crash, shaken but alert enough to look around. Across the street, a gas station sign. Next door, a restaurant has a camera pointing right at the intersection. On the corner, a small "smile, you're on camera" sticker in a shop window. Somewhere, a camera saw exactly what happened.
Now you need to get that video before it disappears.
Most camera systems overwrite old footage automatically. Some replace it within days. A few replace it within hours. If you wait, the single best piece of evidence for your claim could be gone. Here's a simple, step-by-step guide to help you move fast, protect the security camera footage of a car accident, and use it to prove what really happened.
Quick fact: Small business and residential security systems often retain footage for only 7 to 14 days, and some high-traffic loop-recording systems overwrite within 24 to 48 hours. Source: iS3 Technology, "How Long Should Businesses Keep Security Footage?" (2025).
A Real Case Where Video Made All the Difference
Video evidence has solved cases that would have otherwise gone cold. One recent example shows just how powerful it can be.
In the early morning hours of March 22, 2026, a pedestrian in northeast Minneapolis was struck and killed by a driver who fled the scene. Police investigators collected surveillance footage from homes and businesses along Marshall Street NE, plus video from a parked Tesla that captured the collision. Using that camera footage, along with other surveillance systems across Minneapolis and St. Paul, investigators retraced the suspect vehicle's path of travel. The driver, Gabryella Marie Liebgott, 22, was identified, tracked to an auto body shop where she had requested a rushed vinyl wrap, and arrested on April 3, 2026.
Without that video, a hit-and-run driver may have walked free. The lesson is simple. Cameras see more than witnesses, and they do not forget. Your job is to find that footage and lock it down before it gets overwritten.
How to Get Security Camera Footage After a Car Accident: 7 Steps
Here is the process, broken down into clear actions you can take today.
Step 1: Move Within the First 72 Hours
Time is the single biggest enemy in any fight to secure surveillance video car accident evidence. Some cameras overwrite footage within 24 to 72 hours. Others keep it for 30 days. You will rarely know which system you're dealing with, so treat every hour as if the footage is about to be deleted.
Start the camera hunt the same day as the crash, or the very next morning at the latest.
Step 2: Spot Every Camera Near the Crash Scene
Before you leave the scene, or as soon as you're medically cleared, walk the area and look up. Cameras are often small, discreet, or tucked under eaves.
Common places you may consider to check:
- Gas stations and convenience stores
- Traffic signals and highway poles (state DOT cameras)
- Restaurant and retail storefronts
- Bank ATMs and drive-throughs
- Apartment building entrances
- Homes with Ring, Nest, or similar doorbell cameras
- Parking lot light poles
- Buses and public transit stops
Take pictures of each camera you see, along with the building address. That list becomes your roadmap.
Step 3: Ask the Owner Right Away
A polite, face-to-face conversation is often the fastest way to get a store camera accident video released. Most homeowners and small business owners are willing to help if asked promptly and politely.
What to say:
- Explain that there was an accident at the address and time, and their camera may have caught it.
- Ask if they can save the clip and share a copy.
- Leave your name, phone, email, and the exact date and time of the crash.
For bigger businesses, the manager may not have the authority to release the video. Ask for the corporate legal or risk management contact, and move to Step 4 right away.
Step 4: Send a Written Preservation Letter
When informal asks don't work, the next move is to work with a lawyer to issue a formal letter to preserve security footage of the accident. Sometimes called a spoliation letter, this is a written notice telling the business or individual that they hold evidence relevant to a claim, and that they have a duty to keep it.
A preservation letter should include:
- Your full name and contact information.
- The date, time, and exact location of the accident.
- A description of the footage you believe was captured.
- A clear demand that they not delete, alter, or overwrite the footage.
Send the letter by certified mail so you have proof of delivery. If the business deletes the video after receiving your letter, a court may later instruct a jury to assume that the footage would have hurt their side.
Step 5: Get the Cameras Noted in the Police Report
When officers arrive at the scene, point out every camera you see. If an officer reviews or collects the footage for the investigation, it becomes part of the official record, and your attorney can request it directly from law enforcement later.
Even if the officer does not collect the video, ask them to note the cameras in the report. That written record proves the cameras existed and were likely recording when the crash happened.
Step 6: Request Traffic Camera Footage From the Right Agency
Government-run traffic cameras are managed by city police, the state Department of Transportation, or toll authorities, depending on the road. Learning how to get traffic camera footage starts with figuring out who owns the camera.
A few things to know:
- Some state DOT cameras stream live feeds only and do not record at all. South Dakota's DOT 511 system, for example, shows live views but does not store video.
- Red-light and speed cameras typically do record, but agencies usually require a formal public records request or a subpoena to release footage.
- Retention windows for government cameras vary. Some keep footage for only a few days, others for weeks.
Submit your request as soon as possible, and put it in writing.
Step 7: Use a Subpoena When They Refuse
When a business, agency, or individual refuses to hand over the video voluntarily, your attorney can subpoena camera footage of a car accident. A subpoena is a court order that legally requires the party to produce the footage.
Subpoenas are common when dealing with third parties, banks, hotels, or corporate chains, who have no personal stake in your claim but follow strict privacy or policy rules. Refusing a subpoena can result in the party being held in contempt of court, which is why subpoenas usually work quickly.
What Makes the Footage Useful as Evidence
Having the video is only half the battle. For it to be accepted as evidence, a few boxes have to be checked.
- Authenticity. You may need to show that the footage has not been edited. A clear chain of custody, documenting everyone who handled the file from export to courtroom, helps prove this.
- Relevance. The video has to actually show something connected to your accident, like the moments before, during, or right after the crash.
- Quality. High-resolution, date-stamped footage is usually accepted without issue. Grainy or undated footage may get challenged.
A good attorney can use forensic video experts to enhance unclear footage and verify timestamps, turning borderline video into strong evidence.
Conclusion
Cameras are everywhere, but the footage they capture rarely lasts long. If you think a crash was recorded, start asking, requesting, and writing within the first 48 to 72 hours. Waiting even a few days can cost you the single most powerful piece of evidence in your case.

Frequently Asked Questions
Retention times vary widely. Small businesses and home cameras often keep footage for 7 to 14 days, while larger retailers and banks may hold it for 30 to 90 days or more. Some high-traffic loop-recording systems overwrite within 24 to 48 hours, so acting fast is critical.
Yes, and it often works with small businesses and homeowners. Larger companies usually refer the request to corporate legal or risk management. When informal requests are denied, a written preservation letter or a subpoena is the next step.
A preservation letter, also called a spoliation letter, is a formal written notice telling a party they hold evidence related to a claim and must not delete or alter it. Sending one by certified mail creates a paper trail and may trigger legal consequences if the footage is later destroyed.
Sometimes, through a public records request to the city or state agency that operates the camera. But many traffic cameras are live-feed only and do not record. When recordings exist, agencies often require a subpoena from an attorney to release them.
Not always. The video must be authentic, unaltered, and relevant to the case. Courts may reject footage that has no timestamp, is heavily edited, or has a broken chain of custody. A clear, date-stamped clip from a known source is usually accepted.
That claim sometimes turns out to be true, but it is also a common excuse used to avoid sharing damaging footage. An attorney can investigate whether the cameras were operational, request maintenance records, or use a subpoena to force disclosure of the truth.
