Our latest webinar, recorded during the Davidhorn Police Interview Summit 2025, was hosted by Jeff Horn, General Manager of Davidhorn UK. Jeff brought decades of specialised expertise in ensuring that crucial investigative work translates into admissible evidence in court.
In this comprehensive technical presentation, Jeff explored:
- Scientific foundations of police interview recording – Drawing from the original UK trials that established PACE legislation and the lessons learned from historical cases like the Guildford Four
- Audio as primary evidence – Understanding why clear, audible audio takes precedence over video, and the technical requirements for court admissibility
- Room design and environmental considerations – Practical guidance on acoustic treatment, camera positioning, and creating optimal recording environments for both suspect interviews and vulnerable witness suites
- Technology standards for tamper-proof police interview recording – The critical role of Digital Fingerprint (SHA-256), AES-256 encryption, and maintaining chain of evidence integrity
- Specialised considerations for vulnerable witnesses – Technical adaptations needed for child interview suites and trauma-informed recording approaches
