How to add redaction to an existing video management system
Video management systems already sit at the center of many surveillance operations. They collect recordings, organize camera feeds, control access, and give security teams a practical way to search and review footage. But as organizations face greater privacy expectations, one question becomes increasingly important: how can redaction be added without replacing the VMS that already works?
The answer is usually not to start again with an entirely new surveillance architecture. Instead, organizations can introduce a dedicated privacy layer that works alongside their existing video management system. This allows teams to retain established cameras, storage, workflows, and evidence processes while adding automated anonymization when footage needs to be shared.
The key is designing the integration carefully so that privacy protection strengthens the existing environment rather than creating another disconnected manual process.
Start by mapping your existing VMS workflow
Before introducing redaction technology, establish exactly how video currently moves through the organization.
A typical workflow might look something like:
Camera → VMS → Storage → Review → Export → Sharing
However, larger environments can be considerably more complicated. Recordings may move into evidence management systems, investigation platforms, cloud storage, case management software, or external review environments before anyone decides that anonymization is necessary.
Understanding these connections helps determine where redaction should sit. In many cases, processing footage immediately before export or disclosure makes the most sense because the original recording can remain protected inside the VMS.
Keep the original footage intact
Adding redaction should not mean modifying the master recording.
Original video may be needed for investigations, legal proceedings, incident analysis, or other authorized purposes. Altering it permanently could also create questions about evidential integrity.
A better approach is to maintain the original recording under existing VMS permissions and create a separate redacted version when required. The VMS remains the source of truth, while the redaction system handles preparation for external or broader internal sharing.
This separation also makes it possible to create different versions for different audiences without repeatedly altering the original.
Decide when redaction should happen
There are several points where a redaction layer can potentially be introduced.
At Export
A user selects footage from the VMS and sends it to the redaction system before creating a shareable copy. This is often straightforward because it fits naturally into an existing review process.
During Automated Workflows
An organization can configure specific types of recordings to undergo anonymization automatically. This can be useful for high-volume environments where privacy processing follows predictable rules.
Through an API
For organizations with sophisticated software environments, an API can connect the VMS or an intermediate application directly with the redaction engine. This reduces manual file handling and makes privacy processing part of the wider technology architecture.
The right option depends on the organization's VMS, technical capabilities, volume of footage, and disclosure requirements.
Use APIs to avoid manual file transfers
Manual downloading and uploading can quickly become a bottleneck.
An operator may have to locate a recording, export it from the VMS, save it locally, upload it into a separate redaction application, wait for processing, download the finished file, and then return it to the appropriate workflow. Repeating this process hundreds or thousands of times is inefficient and creates opportunities for mistakes.
Secure Redact can be connected to existing applications through APIs, allowing organizations to incorporate automated privacy processing into established workflows. This approach is particularly useful for teams that want redaction to happen behind the scenes rather than introducing another standalone task for every operator.

Identify what needs to be redacted
Not every video requires the same treatment.
A surveillance recording may contain faces, license plates, identification badges, computer screens, documents, or other information that could identify individuals. The relevant privacy risks depend on the context and intended recipient.
For example, a security team sharing footage with an external investigator may need to protect unrelated members of the public, while an internal investigation could justify access to more information.
Redaction policies should therefore be based on purpose and audience rather than simply applying maximum anonymization to every recording.
Look beyond faces
Facial blurring is often the first privacy feature organizations consider, but it should not be the only one.
A person's identity can potentially be established through a combination of visual details. Vehicle registrations, name badges, documents, addresses, screens, uniforms, and other contextual clues may all contain sensitive information.
A redaction layer should therefore be capable of addressing more than faces when the use case requires it. Otherwise, organizations risk creating footage that appears anonymized while still revealing information that could identify someone.
Make redaction work at VMS scale
The volume of footage generated by a modern VMS can make manual privacy editing impractical.
A large camera network may produce thousands of recordings every day, but only a small percentage may eventually need to leave the organization's controlled environment. The challenge is identifying those recordings and processing them efficiently when the need arises.
This is where automated detection becomes valuable. Instead of requiring an editor to locate every face or license plate manually, AI can identify relevant objects and prepare them for anonymization.
Secure Redact uses AI-powered detection and automated object tracking to maintain redactions as people and objects move through video. This can significantly reduce the repetitive work involved in preparing lengthy surveillance recordings, particularly when multiple subjects appear throughout a scene.
Preserve video quality and context
Redaction should not make footage unusable.
An overly aggressive process can obscure important details, while poorly positioned masks can interfere with understanding what happened. The objective should be targeted privacy protection that removes information the recipient does not need while preserving relevant context.
This is especially important for evidence. Investigators may need to understand movement, timing, interactions, and environmental details even when the identities of unrelated people have been concealed.
Quality control should therefore be part of the workflow rather than an optional final step.
Keep access controls consistent
Introducing a separate redaction system creates another environment that needs to be secured.
Organizations should consider how users authenticate, which personnel can access original recordings, who can initiate redaction, and who can approve finished files. Permissions should align with existing VMS roles wherever possible.
This prevents privacy controls from becoming weaker simply because footage has moved outside the primary surveillance environment.
Maintain an audit trail
Privacy processing should be traceable.
Organizations may need to establish which recording was processed, who initiated the workflow, what version was created, and who approved the final output. This is particularly important when footage is being prepared for legal proceedings, regulatory requests, public disclosure, or external investigations.
A clear audit history also makes it easier to investigate mistakes and demonstrate that privacy procedures are being followed consistently.
Don't create another storage problem
Redacted files can quickly accumulate.
If every exported recording produces multiple copies across local drives, cloud folders, email accounts, and third-party applications, organizations can lose track of which version is current and where sensitive information remains stored.
A well-designed integration should define where temporary processing files live, where final versions are retained, and when unnecessary copies are deleted. This reduces both storage overhead and privacy exposure.
Build human review into automated processing
Automation is most effective when it handles repetitive tasks while people remain responsible for final decisions.
A reviewer should be able to inspect automated redactions, correct missed objects, and confirm that the final recording is suitable for its intended audience. This is particularly important in crowded scenes, poor lighting, unusual camera angles, or recordings containing partially obscured subjects.
The objective is not to remove people from the privacy process. It is to make their time more valuable by reducing the amount of repetitive editing they need to perform.
Plan the integration around your existing architecture
There is no universal location for a redaction layer.
Some organizations will benefit from processing exported files through a cloud service. Others may require private infrastructure because of security policies, operational requirements, or the sensitivity of their footage.
Pimloc designed Secure Redact to support flexible deployment options, including cloud, private cloud, hybrid, and on-premise environments. This gives organizations greater freedom to introduce automated privacy processing without automatically forcing their surveillance data into an architecture that conflicts with existing requirements.
Turn your existing VMS into a more privacy-ready environment
Organizations do not necessarily need to replace an established video management system to improve privacy protection. A dedicated redaction layer can extend existing infrastructure, allowing cameras, storage, evidence management, and security workflows to continue operating while automated anonymization is introduced where it is most needed.
The most successful integrations are designed around the organization's existing architecture rather than forcing teams to completely change how they manage video. API connectivity, automated detection, appropriate deployment options, access controls, and human quality assurance can work together to create a privacy workflow that feels like a natural extension of the VMS.
With that approach, redaction becomes part of the video lifecycle rather than a separate administrative chore - giving organizations greater control over what they share without sacrificing the surveillance systems and evidence workflows they already depend on.
