Every Repeat Examination Burdens Witnesses and Delays Proceedings

Standard video conferencing solutions quickly reach their limits in courtroom environments.

Victim Protection Through Separate Questioning

Victims and vulnerable witnesses give evidence from a protected room without facing the accused in court. Clear transmission lets the court perceive facial expressions, gestures and conversational dynamics.

Technical Stability

Hearings and trials must not fail because of unstable connections or poor audio quality. Unreliable technology leads to delays, adjournments and additional organisational effort.

Traceable Documentation

Audio-visual recordings in court must be traceable and processed in line with data protection law. Integrity checks, secure storage and logged access are core requirements.

Legal Framework for Video Hearings in Court

Example: key provisions for audio-visual recordings under German law.

§ 247a StPO

Remote examination during trial: allows a witness to be examined outside the courtroom by video link.

§ 168e StPO

Separate questioning in a protective situation: allows evidence to be given in a protected environment without confrontation.

§ 255a StPO

Playback of recorded examinations at trial as evidence, instead of a repeat examination.

§ 58a StPO

Audio-visual recording during the investigation: basis for interview recordings used in court.

§ 128a ZPO

Video hearings in civil proceedings: allows oral hearings by video conference.

The Méndez Principles in Court Proceedings

The Méndez Principles describe questioning without coercion, built on rapport and traceable documentation. The Mangold system supports the implementation of the Méndez Principles by capturing evidence given from a protected room completely in sound and vision. Vulnerable people give evidence without confrontation, and the court can review every examination afterwards.

Frequently Asked Questions

Which legal provisions govern courtroom AV recording?

This depends on the jurisdiction. In Germany, for example, Sections 247a, 168e, 255a and 58a of the German Code of Criminal Procedure (StPO) and Section 128a of the German Code of Civil Procedure (ZPO) govern remote examination, separate questioning, playback of recorded evidence and video hearings. Mangold International designs each system around the requirements of your court.

How is recording integrity ensured?

Every recording is assigned a checksum and can be encrypted with AES-256. Case number, date and time stamp are embedded as a live overlay in each camera image. An automated integrity check during playback detects any alteration. The recording is therefore designed for use as evidence in court.

Can multiple cameras be deployed in a courtroom?

Yes. The Mangold system supports multi-camera recording with individual PTZ control, for example for witnesses, the bench, the defence and the prosecution. Camera switching can automatically focus on the person currently speaking.

How does remote witness testimony work?

For remote testimony, the witness is questioned in a protected room while judges, defence and prosecution follow the proceedings in another room. The Mangold system transmits sound and vision without dropouts and records both rooms synchronously, with Voice-of-God communication for judicial directions.

Which judicial requirements does the system support?

The Mangold system uses encryption in line with BSI-recommended methods, detects any alteration of recordings through checksums and supports chain-of-custody documentation. Role-based access rights and audit logs are standard.

Can the system support online or remote hearings?

Yes. The system supports online hearings with professional AV quality in both directions: participants in the courtroom see and hear remote attendees and vice versa. Redundant recording ensures that no hearing remains undocumented.

What evidence packages can be exported?

The system exports standard video formats for broad judicial compatibility, encrypted judicial packages for secure transfer between agencies, and redacted versions with watermarks for case file inspection. Automated PDF reports including metadata and proceeding markers are also available.

Does the system support the Méndez Principles?

The Mangold system supports the implementation of the Méndez Principles. Evidence given from a protected room is documented completely and synchronously in sound and vision, so every examination remains traceable for the court and all parties.
