- Can deleted DVR footage really be recovered?
In many cases, yes. When footage is deleted from a DVR, the underlying video data often remains on the hard drive until it is overwritten by new recordings. How much is recoverable depends on how soon the drive was secured, how aggressively the DVR overwrites old data, the number of channels recording, motion detection versus continuous 24/7 recording format, the size and number of the storage drives and the condition of the hardware.
- What is the success rate of DVR recovery?
If the equipment has been preserved, the success rate of recovery goes up. If the equipment was recording over the data for several years on the original storage drive, the success rate for recovery goes down.
- How is this different from hiring a regular data recovery company?
Standard data recovery retrieves files — it is not designed to produce legally defensible evidence, and often does not have access to specialized forensic video recovery tools. Forensic video recovery requires hardware write blockers, cryptographic hash verification, chain of custody documentation, and experts qualified to interpret the information and testify in court. Primeau Forensics applies all of these best practices in standard practice.
- Will recovered footage hold up in court?
Footage recovered using proper forensic methodology and authenticated by a qualified expert witness has a strong track record of admissibility. The key requirements under Federal Rule of Evidence 901 are that the evidence is what it claims to be and that it has not been altered. We have expert testimony and experience in the authentication of recovered video data in real court cases.
- How long does a DVR forensic recovery take?
Timelines depend on the condition of the drive, the volume of data, and the complexity of the video container. We provide a scope estimate during your initial evaluation. Most cases are completed within 1–3 weeks. Expedited services are available for time-sensitive matters.
- Can you travel for on-site DVR inspections?
Yes. For enterprise NVR systems or situations where the equipment cannot be safely transported, or the equipment is not legally permitted to be released from the custody of the custodian, our experts travel to the location. We have conducted on-site inspections across the United States.
- What DVR brands do you work with?
We have experience with all major manufacturers including Hikvision, Dahua, Samsung, Q-SEE, NightOwl, Lorex, Swann, and many others. Contact us with your brand and model — the brand is typically all we need to assess compatibility.
- What do you need to start an evaluation?
For an initial evaluation, we need: the DVR/NVR brand and model (if known), the size and number of storage hard drives, the number of cameras that were in use at the time the video was recorded, a description of what footage you are trying to recover and approximately when it was recorded, and any information about the current state of the equipment.
CCTV DVR Data Recovery Services
DVR & CCTV Video Recovery for Legal Investigations
When surveillance footage is deleted, overwritten, or damaged, Primeau Forensics recovers it using court-admissible forensic methodology. Serving attorneys, law enforcement, and insurance investigators nationwide.
Forensic Video Recovery
Digital video recordings are fragile by nature and require specialized knowledge, training, and equipment to recover accurately while preserving digital integrity.
In legal cases, surveillance footage is often the most important evidence in the record. Our forensic methodology ensures that recovered video is handled correctly from the moment we receive it — protecting both the evidence and your case.
We recover deleted, damaged, overwritten, and corrupted footage from CCTV DVR and NVR systems using court-admissible procedures, and our experts are available to testify to every step taken.

Who We Serve
We work exclusively with legal professionals and investigators who need video evidence handled correctly the first time.
Attorneys
Civil litigators, criminal defense attorneys, and prosecutors rely on our forensic video recovery to establish facts, authenticate evidence, and support their case strategy. We provide expert reports and can testify to our methodology.
Corporations
Many small, medium, large and enterprise level companies need to preserve video evidence of an incident in anticipation of a legal case. We can assist with preservation of that evidence both logically and physically.
Insurance Companies
Claims investigators and SIU teams use our services to verify or challenge claims involving fires, accidents, slip-and-falls, and property crimes. Surveillance footage recovered forensically provides an objective factual record.
Before You Do Anything With That DVR or Hard Drive
Three actions commonly destroy recoverable evidence before it ever reaches an expert: plugging the drive back into a DVR (which can trigger an automatic format), handing it to general IT unfamiliar with forensic protocols, or attempting DIY recovery software. If that evidence becomes damaged or accidentally overwritten, recovery becomes more difficult, sometimes impossible.

Our DVR Forensic Recovery Process
A structured, documented approach that keeps evidence legally defensible at every stage. Our recovery tools can retrieve data from various DVR hard disks hard, including MDVR, CCTV DVR, and NVR. In addition, we have experience with multiple manufacturers, such as Hikvision, Samsung, Q-SEE®, NightOwl, Lorex, and many more.
1. Evidence Intake & Evaluation
We document the device condition, assign a unique case number, and assess what footage may be recoverable. You receive a scope summary before any paid work begins.
2. Write-Blocked Drive Imaging
The drive is imaged through a hardware write blocker — preventing any alteration to original media. A SHA-256 hash is computed before and after to verify bit-level integrity.
3. Data Scanning & Recovery
We scan the forensic image for recoverable footage using advanced tools not available in consumer software. Deleted, overwritten, and corrupted segments are identified and extracted.
4. DVR Log File Analysis
System logs record motion events, user logins, date/time changes, and recording gaps. These logs can establish a timeline independent of the video footage itself.
5. Results Review & Delivery
We walk you through findings in a conference call before final delivery. Recovered footage is provided in a standard, court-ready format with a written forensic report.
6. Expert Witness Support
If the case goes to trial, our certified experts authenticate the recovered evidence and explain the methodology to a judge or jury in plain, accessible language.
Types of Cases We Support
Surveillance footage from DVR systems is frequently the most critical evidence in criminal cases — robberies, assaults, homicides, and sexual assault investigations. We recover footage from damaged, deleted, or proprietary-format DVRs and provide expert testimony on the authenticity and integrity of recovered recordings. Our documentation supports both prosecution and defense, depending on who retains us.
Slip-and-falls, premises liability, vehicle accidents, and workplace injury cases often hinge on whether surveillance footage was properly preserved. We recover footage that businesses claim was deleted or unavailable, and can evaluate whether recordings were altered or selectively withheld. Our forensic reports are prepared to withstand deposition and cross-examination.
Insurance SIU teams and claims adjusters retain us to recover and authenticate surveillance footage for fire investigations, theft claims, liability disputes, and staged accidents. We also analyze DVR system logs to determine whether recordings were deleted, when the system was accessed, and whether date/time settings were altered — all of which can be dispositive in a fraud investigation.
When a law enforcement agency encounters a DVR system with proprietary video formats, physical damage, or deleted footage beyond in-house capabilities, we provide forensic extraction services that hold up to evidentiary scrutiny. We work under non-disclosure agreements and can appear as expert witnesses in federal and state proceedings.
Employee misconduct, theft, discrimination claims, and harassment investigations increasingly rely on workplace surveillance footage. We recover footage from corporate NVR systems and document our chain of custody to support internal HR investigations, EEOC proceedings, and employment litigation.
What We Can Recover & How
Fire Damaged Cameras & DVRs
Using forensic-grade imaging tools, controlled cleaning techniques, and specialized hardware interfaces, we can often extract usable data from devices affected by extreme heat, smoke, water, and structural deformation. Even when housings are melted or electronics are compromised, our laboratory process isolates surviving storage components, stabilizes them, and performs sector‑level data acquisition to preserve any remaining footage.
Log File Analysis
It should be noted, administrative, user, system, and network logs are typically stored on the DVR/NVR system that initially recorded the evidence. In fact, these files can be critical to evaluating motion detection, date/time, and user interaction.
Repair Damaged/Corrupt NVR Files
New video formats are surfacing with various playback issues. For example, CCTV systems commonly record in a file format that houses the native language (DAV, G64, EXE). Importantly, this native language can contain native timing and other information necessary for forensic investigation. As a result, if correctly handled, video evidence can be protected and played correctly. In fact, our advanced recovery services can repair or reconstruct the video file to correct playback issues.
Lab Recovery
Our data recovery experts use the latest tools and technology to collect video evidence accurately. The DVR hard drive recovery scanning process will determine if data beyond reach is recoverable, as well as recover accessible data. In any case, readily accessible CCTV surveillance videos can be extracted and preserved for further evaluation and investigation.
Site Inspection Recovery
Digital video recording systems can be complicated and extensive. For example, in cases where more complex NVR systems are used, the system cannot be transported. As a result, we can travel to the location and inspect the system to determine if the video is recoverable. In fact, a site inspection investigation may reveal other important details that can assist with a case.
Or comparatively, why wasn't the video recorded at the time of the incident?
