Quick Insights
- Surveillance video can provide powerful, objective evidence showing exactly how an accident occurred and who was at fault.
- Footage may be available from nearby businesses, homes with doorbell cameras, traffic cameras, public transit vehicles, dashcams, parking garages, or security systems.
- Video evidence can establish liability, confirm the timeline of events, document dangerous conditions, and refute conflicting witness testimony or false claims.
- Many surveillance systems automatically overwrite recordings within days or weeks, making it critical to act quickly.
- An attorney can send preservation (or “spoliation”) letters requesting that businesses, government agencies, and other parties preserve relevant footage before it is deleted.
- The sooner surveillance evidence is identified and secured, the greater the likelihood it can strengthen a personal injury claim.
Sometimes the Camera Sees Everything
After a serious accident, people often have very different versions of what happened.
One driver insists they had the green light.
Another claims the pedestrian stepped into traffic unexpectedly.
A property owner argues that a dangerous condition didn’t exist.
Witnesses may remember events differently, and memories naturally fade over time. Unfortunately, those conflicting accounts can make it difficult to determine exactly what happened.
Fortunately, surveillance cameras are becoming increasingly common.
From storefront security systems and residential doorbell cameras to dashcams and traffic cameras, video footage can capture accidents from multiple angles – providing an objective record that often removes much of the uncertainty surrounding a personal injury claim.
In many cases, surveillance footage becomes one of the most persuasive pieces of evidence available.
Why Surveillance Video Is So Valuable
Unlike eyewitness testimony, surveillance video does not rely on memory.
It records events as they happen.
When available, video footage can help answer critical questions such as:
- How did the accident occur?
- Who had the right of way?
- Was someone speeding?
- Did a driver run a red light?
- Was a property hazard present?
- How long had the dangerous condition existed?
- Did the injured person contribute to the accident?
- Were warning signs present?
Rather than relying solely on competing stories, attorneys, insurance adjusters, judges, and juries may be able to review the actual incident.
That objective evidence can significantly strengthen a personal injury claim.
How Surveillance Footage Helps Prove Liability
One of the primary goals of any personal injury case is establishing liability.
Video footage can often demonstrate negligence far more effectively than testimony alone.
For example, surveillance may show:
- A distracted driver looking down at a phone.
- A vehicle running a stop sign.
- A speeding driver entering an intersection.
- A truck making an unsafe lane change.
- A business employee failing to clean up a spill.
- A property owner ignoring a dangerous hazard.
- A dog escaping through a broken gate before attacking someone.
When liability is disputed, video can eliminate much of the speculation by showing exactly what occurred.
It Can Confirm the Timeline of Events
Timing often matters in personal injury cases.
Surveillance footage can establish:
- When the accident happened.
- How long a dangerous condition existed.
- Whether employees inspected an area beforehand.
- Whether anyone attempted repairs.
- How quickly emergency responders arrived.
- What occurred immediately before and after the incident.
For example, in a grocery store slip and fall case, video might reveal that a liquid spill remained on the floor for over an hour without being cleaned up or marked with warning signs.
That evidence could help demonstrate that the business had sufficient time to discover and correct the hazard.
Surveillance Video Can Help Document Dangerous Conditions
Some hazards disappear shortly after an accident.
Examples include:
- Wet floors
- Ice accumulation
- Fallen merchandise
- Loose floor mats
- Broken stairs
- Obstructed walkways
- Poor lighting
- Construction debris
Property owners often repair hazardous conditions soon after an incident occurs.
Without photographs or surveillance footage, proving that the dangerous condition existed may become much more difficult.
Video can preserve what the scene looked like before any changes were made.
It Can Counter False Claims
Insurance companies frequently dispute personal injury claims.
Common arguments include:
- The accident didn’t happen the way you described.
- You caused the accident.
- Your injuries aren’t consistent with the collision.
- The dangerous condition didn’t exist.
- You weren’t paying attention.
Surveillance footage can directly contradict these arguments.
Rather than relying on competing narratives, the video provides an impartial account of what occurred.
That can be especially important when the opposing party changes their story or denies responsibility altogether.
Where Surveillance Video May Be Found
Many people assume surveillance footage only comes from security cameras inside businesses.
In reality, valuable video evidence may come from a wide variety of sources.
Nearby Businesses
Retail stores, restaurants, gas stations, banks, hotels, office buildings, shopping centers, warehouses, and parking garages often have exterior security cameras.
Depending on camera placement, these systems may capture:
- Vehicle collisions
- Sidewalk accidents
- Parking lot incidents
- Pedestrian accidents
- Slip and falls near entrances
Even if the accident occurred just outside the property, nearby cameras may still have recorded it.
Residential Doorbell Cameras
Video doorbells have become incredibly common throughout California.
Homes located near intersections, sidewalks, driveways, apartment buildings, or residential streets may have recorded:
- Car accidents
- Bicycle crashes
- Pedestrian accidents
- Dog attacks
- Hit-and-run collisions
Neighbors often don’t realize their cameras captured an incident unless someone asks.
Traffic Cameras
Some intersections are monitored by traffic cameras or other government-operated systems.
Depending on the location, available footage may capture:
- Traffic signal changes
- Vehicle movements
- Intersection collisions
- Turning vehicles
- Pedestrian crossings
Not every traffic camera records video continuously, and not all recordings are retained for the same length of time, making prompt investigation essential.
Dashcams
More drivers than ever use dashboard cameras.
A dashcam belonging to:
- You
- Another driver
- A rideshare driver
- A commercial truck
- A passing motorist
may have recorded the collision.
Even drivers who weren’t involved in the accident may possess valuable footage.
Public Transit Cameras
Many buses, trolleys, trains, and other public transportation vehicles have multiple onboard cameras.
These systems may capture:
- Vehicle collisions
- Passenger injuries
- Pedestrian accidents
- Bus stop incidents
- Dangerous driver behavior
Because transit agencies often have their own policies governing video retention, requests should be made as quickly as possible.
Parking Garages and Parking Lots
Parking facilities frequently utilize extensive surveillance systems.
These cameras may capture:
- Vehicle impacts
- Slip and falls
- Pedestrian accidents
- Security incidents
- Hit-and-run crashes
Multiple camera angles can often provide a more complete picture of what happened.
Why You Must Act Quickly
Perhaps the biggest mistake accident victims make is assuming surveillance footage will always be available.
Unfortunately, that’s rarely the case.
Many surveillance systems automatically overwrite recordings after a relatively short period.
Depending on the system, footage may only be retained for:
- A few days
- One or two weeks
- Thirty days
- Slightly longer retention periods
Some systems overwrite footage continuously once storage capacity is reached.
If no one requests preservation before that happens, critical evidence may be permanently lost.
What Is a Preservation Letter?
A preservation letter – sometimes called a spoliation letter – is a formal request sent to a business, property owner, government agency, or other party directing them to preserve potentially relevant evidence.
In surveillance cases, the letter may request that the recipient retain:
- Security camera footage
- Digital recordings
- Dashcam files
- Incident reports
- Inspection records
- Maintenance logs
- Photographs
- Other electronic evidence
Sending a preservation letter promptly can help prevent important evidence from being routinely deleted under normal retention policies.
If a party destroys relevant evidence after receiving notice that litigation is reasonably anticipated, courts may impose sanctions or allow adverse inferences in certain circumstances.
An Attorney Knows Where to Look
One of the biggest advantages of hiring an experienced personal injury attorney early is that they know where valuable surveillance evidence may exist.
An attorney can quickly investigate:
- Nearby businesses
- Adjacent office buildings
- Apartment complexes
- Government agencies
- Homeowners with doorbell cameras
- Commercial trucking companies
- Rideshare vehicles
- Public transit systems
- Parking facilities
Rather than waiting for the insurance company to conduct its own investigation, your legal team can begin locating and preserving evidence immediately.
Surveillance Video Can Make the Difference
Not every personal injury case includes surveillance footage.
But when it does, video evidence can dramatically strengthen a claim by providing objective proof of liability, documenting dangerous conditions, confirming timelines, and exposing inaccurate or misleading accounts of what occurred.
The challenge is that this evidence often disappears quickly.
That’s why prompt action is so important after any serious accident.
