What AV is best for a barristers' chambers?

Chambers AV is fundamentally different from a solicitors' firm because of the chambers structure (a set of self-employed members sharing a building rather than employees of a single firm), the prevalence of listed-building constraints in Inner Temple, Middle Temple, Lincoln's Inn and Gray's Inn, and the requirement for hybrid hearing rooms that work for Crown Court and arbitration tribunals via Microsoft Teams or the relevant court video service.

Three room types dominate the chambers brief:

• Hybrid hearing rooms for Crown Court appearances, arbitration tribunals and remote witness work. The setup needs multi-camera coverage of bench, counsel and witness, court-grade audio capture (Shure ceiling arrays into a Q-SYS or Biamp DSP), platform compliance with the Cloud Video Platform (CVP), and a lectern microphone for counsel addressing the camera. Many sets now run two of these, recognising the post-2020 baseline of hybrid attendance.
• Shared client meeting rooms booked by individual members for conferences with instructing solicitors and lay clients. Standard meeting room AV (display, ceiling mics, single-cable USB-C bring-your-own-laptop), but with a deliberate position on recording. Some sets prohibit any recording in client conferences; others permit it under written consent. The room booking system, control panel and recording governance need to enforce that policy.
• Pupillage interview rooms with reliable hybrid VC. Pupillage interviews are now routinely hybrid, and a glitchy connection during a pupillage shortlist is the kind of failure that lands in the trade press.

Listed-building constraints are the single biggest design factor. Period oak panelling, plaster ceilings, original cornices and Grade II or Grade II* listing in Temple buildings mean cable routing has to go through floor voids, behind skirting, or via demountable trunking that respects the heritage finish. Wall-mounted touch panels often won't be permitted on panelled walls, pushing control to a tabletop puck or a tablet on the conference table. Surface-mounted speakers on a listed plaster ceiling typically need listed building consent, which adds 8 to 12 weeks to the programme. Engage a legal-sector AV specialist early enough to integrate with the conservation architect's drawings.

Recording governance varies by set. Some chambers prohibit recording entirely on professional conduct grounds, others permit it with the express written consent of all parties, and a small number record everything to a private archive accessible only to the member. The AV control system needs to enforce whichever policy the head of chambers has written into chambers procedure.

Quick reference: hybrid hearing rooms (multi-camera, court-grade audio, CVP-compatible), shared client conference rooms (with explicit recording governance) and pupillage interview rooms, all delivered with listed-building cable routing and listed building consent timelines factored in.
