Overview#
An armed robbery is captured on three separate CCTV cameras, each recording at different frame rates, resolutions, and with clocks drifted by minutes from each other. The suspect wore a hood, but one camera captured a distinctive gait as he left the building. Another captured partial licence plate digits from the getaway vehicle. A third camera's footage, when stabilized and contrast-enhanced, reveals a tattoo on the suspect's wrist. Synchronising the three streams and enhancing each selectively turns fragmentary footage into a comprehensive forensic picture that identifies both the suspect and the vehicle.
The Video Forensics module provides professional-grade forensic video analysis for law enforcement agencies, government forensic laboratories, military investigations, and intelligence organisations. Scientific methodology and courtroom admissibility guide every feature, from evidence ingestion through final court presentation. The system does not simply enhance video; it documents every step taken and justifies every conclusion reached.
Open Standards#
- STANAG 4609 / MISB ST 0601 (Key-Length-Value): Video streams carrying embedded sensor metadata (GPS coordinates, timestamps, platform telemetry) are ingested and validated against STANAG 4609 Edition 4 codec and container requirements, with KLV packets parsed per MISB ST 0601 mandatory key rules.
- W3C Verifiable Credentials Data Model v2.0: Every evidence item and chain-of-custody transfer is wrapped in a VC DM v2.0 credential signed with Ed25519, allowing courts and prosecutors to cryptographically verify provenance without trusting a proprietary ledger.
- ISO 19005 (PDF/A): Court packages and forensic reports are exported as ISO 19005-conformant archival PDFs (PDF/A-1B through PDF/A-4F), ensuring long-term readability and admissibility without dependency on proprietary rendering software.
- SHA-256 and BLAKE2b (NIST FIPS 180-4 / RFC 7693): All ingested video files and evidence objects are integrity-hashed on arrival using SHA-256 as the primary digest and BLAKE2b as a secondary, with hashes recorded in the chain-of-custody log and re-verified on every access.
- EXIF / ISO 12234-2: Camera metadata embedded in video frames and still captures (GPS coordinates, capture timestamps, device model, lens settings) is extracted and parsed per the EXIF standard to establish device provenance and corroborate recorded timelines.
- ISO 8601: All timestamps across evidence records, chain-of-custody events, and exported reports are encoded in ISO 8601 format, providing unambiguous temporal references for multi-timezone investigations and cross-agency data sharing.
- GraphQL: The full evidence management, chain-of-custody, and video-metadata surface is exposed through a typed GraphQL API, enabling court systems, case management platforms, and external forensic tools to query and mutate records with a consistent, self-documenting interface.

Key Features#
Video Enhancement#
Advanced video enhancement improves the quality of degraded or low-resolution footage through noise reduction, resolution upscaling, stabilization, and contrast optimisation. The goal is clearer identification of subjects, vehicles, and objects in surveillance recordings while maintaining full documentation of every processing step applied.
Frame Analysis#
Frame-by-frame analysis tools enable detailed examination of video evidence, supporting measurement, annotation, object tracking, and temporal analysis across individual frames and frame sequences. Examiners can mark, measure, and annotate specific frames for inclusion in court exhibits.
Deepfake Detection#
Automated detection of digitally manipulated or synthetically generated video content identifies artefacts and inconsistencies that indicate face-swapping, AI-generated imagery, or post-capture manipulation. In an era where synthetic media can be produced rapidly and cheaply, verifying evidence authenticity before relying on it is not optional.
Camera Identification#
Source camera identification determines which device captured a specific video through sensor pattern noise analysis, metadata examination, and codec signature matching. Linking footage to specific recording equipment is often a critical step in establishing provenance and chain of custody.
Timestamp Verification#
Timestamp analysis verifies the temporal authenticity of video evidence, detecting clock manipulation, metadata inconsistencies, and frame rate anomalies. Reliable timelines for investigative and legal proceedings depend on knowing exactly when footage was recorded, not just what a device's internal clock reported.
Evidence Chain of Custody#
A complete, tamper-evident chain of custody covers all evidence and analytical products. Every access, modification, and transfer is documented with timestamp, user identity, and action taken. Court-ready documentation is generated automatically for legal proceedings.
Reporting and Documentation#
Automated report generation compiles investigation findings, analytical results, and supporting documentation into structured case files. Customisable templates support agency-specific reporting requirements and court presentation formats. Export capabilities deliver reports in multiple formats for distribution to prosecutors, legal teams, and court systems.
Use Cases#
- Surveillance footage enhancement improving image quality for subject and vehicle identification.
- Body-worn camera analysis correlating video evidence with incident timelines.
- Multi-camera synchronisation combining footage from different sources into a unified timeline.
- Video authentication verifying integrity for court proceedings.
- License plate extraction from surveillance video for vehicle identification.
- Deepfake detection verifying the authenticity of video evidence before judicial use.
Integration#
- Case management systems for investigation workflow integration.
- Evidence management platforms for digital and physical evidence.
- Law enforcement databases and information sharing networks.
- Surveillance and sensor systems for data collection.
- Court and prosecution systems for case preparation.
- Audio forensics for synchronised audiovisual analysis.
