What is Magnet WITNESS?

Magnet WITNESS is a digital video evidence capture tool designed specifically for forensic investigators, analysts, and legal professionals who need to preserve video from sources where direct export isn’t possible or desirable due to time constraints.

Instead of relying on third-party vendors or clunky export processes that often compromise quality or access, WITNESS offers a reliable, court-admissible method for securing evidence from even the most challenging systems. With a strong focus on forensic integrity, it ensures that what you capture can be confidently used in legal and investigative contexts.

Who Uses Magnet WITNESS?

Magnet WITNESS is relied on by professionals in fields where secure, verifiable video evidence is critical — particularly when dealing with restricted systems or on-site playback tools.

  • Law enforcement units and digital forensic teams capturing footage from older or locked-down DVR systems.
  • Security consultants and private investigators collecting streamed surveillance footage from web-based interfaces or proprietary viewers.
  • Legal teams and expert witnesses securing playback evidence for case files or disclosure.
  • Government agencies and corporate security teams managing compliance cases, internal reviews, or audit trails.

It’s especially valuable in time-sensitive scenarios where waiting for IT or vendor support could risk the loss of critical evidence.

Key Benefits

Establish timelines, reconstruct events, and identify suspects and victims in cases from robbery to national security.

Preserve video when export options are limited

Maintain evidential integrity

Time-synced, tamper-resistant recordings ensure the captured footage is clear, verifiable, and court-ready.

Why Use Magnet WITNESS?

Not all CCTV recording systems are built with export or investigation in mind. Many legacy CCTV systems, cloud-based surveillance platforms, and proprietary DVRs limit how, or if, footage can be extracted in a usable format for forensic analysis. The DVRs are often password-protected, and the GUI is different from manufacturer to manufacturer and model to model, resulting in significant time being wasted tracking down the password or user manuals. Using WITNESS will get you to the review stage much faster, helping to find those crucial case-cracking images.

Magnet WITNESS helps bridge the gap between inaccessible systems and the need for reliable, presentable video evidence. Instead of facing delays or data loss due to export restrictions, WITNESS provides an investigator-controlled solution that works in real time.
