Denver Police allows people to request HALO and recording traffic-camera video through its online records system. However, the department says unpreserved footage may be overwritten within 15 to 30 days. Check the official HALO camera map, identify the exact location and time, and submit a request that expressly asks the department to preserve the recording while the request is processed.
Do not wait for the insurance company, a completed crash report, or a decision about hiring a lawyer. Denver’s portal currently warns that some video requests take six to eight weeks. That delay does not stop unpreserved video from being overwritten. This short window can be especially important when fault is disputed in a Denver car accident claim.
A visible camera does not guarantee useful video exists. It may show only a live view, face another direction, or belong to CDOT, RTD, a private owner, or another agency.
If a Denver traffic camera may have recorded a crash, take these steps as soon as possible:
A five- or ten-minute window is easier to search than several hours. Use 911 call history, messages, receipts, vehicle data, or the crash report to narrow an uncertain time. Asking for preservation does not guarantee that a recording was found or saved. Keep the confirmation and ask for written notice of whether the video was preserved.
HALO stands for High Activity Location Observation. Denver Police uses this network to monitor public streets and other high-activity locations.
Denver publishes an interactive HALO camera map. Search for the crash address or intersection, zoom in, and note any camera near the scene. Record the camera’s mapped location and take a screenshot for your files.
The map does not prove that a recording exists. A nearby camera may have faced away, moved between views, been blocked, or been unavailable. Describe the collision clearly enough for staff to search.
The Denver Police records page states that unpreserved video from HALO or recording traffic cameras is overwritten between 15 and 30 days.
The safe approach is to treat 15 days as the working deadline. Submit the request immediately, even if the crash report is not ready. In the description, ask Denver Police to preserve the identified footage while the request, payment, review, and delivery are pending.
This is a practical preservation target, not a statutory filing deadline or a guarantee that footage will remain available for 15 days.

The camera’s location and purpose often determine who controls it.
| Possible video source | Likely holder | Where it may be useful |
|---|---|---|
| HALO or Denver recording traffic camera | Denver Police Department | Denver streets, intersections, and public areas |
| CDOT roadway camera | Colorado Department of Transportation | I-25, I-70, U.S. highways, and state-controlled roads |
| RTD camera | Regional Transportation District | Buses, trains, stations, crossings, and park-n-Rides |
| Denver International Airport camera | Denver International Airport | Terminal roads, parking, pickup areas, and airport property |
| Business or residential camera | Property owner or system user | Storefronts, parking lots, entrances, doorbells, and driveways |
| Vehicle camera | Driver, fleet owner, rideshare company, or trucking company | Dashcam, onboard safety video, and outward-facing fleet footage |
The location alone does not identify the camera owner. A collision inside Denver may involve a state highway, RTD property, or a privately operated camera. More than one request may be needed.

Denver Police directs HALO and recording traffic-camera requests through its online records portal. The portal is also used for police audio, video, photographs, and body-camera footage.
Before starting, gather:
In the request, identify the record as HALO or traffic-camera video. State that the material relates to a traffic collision and ask for immediate preservation while the request is reviewed.
The system requires requesters to confirm that the records will not be used to solicit business for financial gain. Answer every statement truthfully and describe the purpose accurately.
A clear request can read:
Please immediately preserve and provide any available HALO or recording traffic-camera video showing the collision at [intersection or address] on [date] between [start time] and [end time]. The vehicles were traveling [directions of travel]. The collision involved [brief vehicle or pedestrian description]. Denver Police case number [number], if available. The HALO map shows a camera near [camera location]. Please preserve the original recording and its file details, including time stamps, while this request is reviewed.
Match the wording to the facts, and do not claim a camera recorded the crash unless you know it did. Answer requests for clarification promptly.

Denver Police currently lists an initial $20 research fee for HALO and traffic-camera video, with added hourly charges when preservation or delivery requires more work. The final cost depends on the request.
The online portal currently says the Civil Liability Section is taking about six to eight weeks to provide records after it receives the information needed to process a request. Open investigations, criminal cases, privacy protections, redactions, technical issues, and the length of the recording can affect release.
Preservation and delivery are different steps. Submitting a request does not confirm that Denver found or saved a recording. Keep the confirmation and ask whether the video was preserved. Confirm current fees and timing on the official records page.
Traffic-camera video is only one part of a crash investigation. Denver Police also accepts requests for:
These records may show witness statements, vehicle positions, road conditions, or visible injuries. Open cases and privacy rules can restrict release. Crash reports are ordered separately and usually become available five to seven days after they close. Self-filed online reports must be obtained through Colorado’s crash-reporting system.
No. CDOT operates traffic cameras along many interstates and state-controlled roads, including major sections of I-25 and I-70. Those cameras are separate from Denver Police’s HALO network.
Do not assume that a live image on COtrip means saved video exists. If a CDOT camera may be relevant, identify the route, direction, mile marker, interchange, exact time, and visible camera. Then use CDOT’s Colorado Open Records Act process to ask whether saved video or related records exist and to request preservation.
CDOT’s fee guidance says staff-time charges apply when a request requires more than one hour of research or retrieval. It does not guarantee that a record exists. Commercial-truck crashes may also produce video from fleet systems, onboard cameras, and nearby businesses. Strong Law’s Denver truck accident lawyer page explains why trucking-company evidence may require a separate preservation effort.
RTD has a Video Investigation Unit that supports its transit-police operations. A crash involving a bus, train, crossing, station, or park-n-Ride may have been recorded even when no HALO camera was nearby.
RTD accepts Colorado Open Records Act requests through its open-records portal. A request does not guarantee that RTD has releasable video from the location and time at issue.
Include the bus or vehicle number, route or train line, station or crossing, direction, and exact time. Ask for immediate preservation. If an RTD vehicle was involved, use the proper claims process too. A records request is not an injury claim.
A store, hotel, apartment, parking garage, office, or home may have a better view than a public camera. A camera away from the impact point may show a vehicle’s approach, lane, direction, or flight from a hit-and-run.
Record every visible camera and property address. Contact the owner or manager quickly and ask that the relevant time window be preserved.
A private preservation notice should identify:
The owner may provide a copy, save it without releasing it, require a subpoena, or decline. Keep the notice and proof of delivery.
For a pedestrian or bicycle collision, video may show a turning vehicle, crosswalk use, signal phase, lighting, or a driver leaving the scene. Strong Law provides more guidance on its Denver pedestrian accident lawyer page.
No recording does not mean there is no case. Use other evidence:
If an agency says no record exists, keep the response. The camera may not have been recording, the request may have used the wrong details, or the retention period may have passed. A denial or delay may also result from an open investigation, privacy issue, technical problem, or overly broad request.
Not by itself. A recording may show a red light, unsafe turn, lane change, speed pattern, crosswalk, impact, or hit-and-run vehicle. It may also leave important questions unanswered because of distance, angle, darkness, missing audio, or blocked views.
Video should be compared with the signal sequence, roadway layout, witness accounts, vehicle damage, crash report, medical evidence, and data from the vehicles involved.
Colorado follows a modified comparative-negligence rule. Compensation may be reduced by the injured person’s percentage of fault, and recovery is generally barred when that person is found 50% or more at fault. Video may be important when the parties disagree about signals, lane position, speed, or right of way.
No. A person can use the public request systems without a lawyer. For a property-damage-only crash with clear facts, handling the request and claim directly may be reasonable.
A legal consultation may make sense if:
An attorney can identify camera holders, send preservation notices, follow records procedures, and use formal discovery if a lawsuit becomes necessary. That does not guarantee useful video exists.
Denver Police says unpreserved HALO and recording traffic-camera video may be overwritten between 15 and 30 days. Treat 15 days as the practical deadline and request preservation immediately.
Denver Police provides an online process, subject to legal restrictions. Requesters must answer required statements truthfully, provide enough detail to locate the recording, and pay applicable fees.
Denver Police currently lists a $20 initial research fee, plus possible hourly charges for preservation or delivery. The total depends on the request. Check the official Police Records page for current charges.
Denver’s portal currently estimates six to eight weeks for the Civil Liability Section to provide records after it has the needed information. Submit immediately because that timeline is much longer than the normal 15-to-30-day overwrite window.
No. A visible camera or live traffic feed does not prove that historical footage exists. The camera may not record, may face another direction, may be temporarily unavailable, or may be controlled by an agency other than Denver Police.
Look for business, apartment, parking, doorbell, dashcam, fleet, rideshare, RTD, and witness video. Also preserve crash reports, 911 records, photos, vehicle data, damaged property, witness information, and medical records.
No. Video can be strong evidence, but it must be verified as accurate, viewed in context, and compared with the other facts. It may support or weaken a claim depending on what it shows.
When serious injuries are involved, waiting can allow helpful video to be overwritten. Strong Law Accident & Injury Attorneys can review where the crash occurred, identify possible video sources, and take steps to preserve evidence while handling the insurance claim.
