ROOM A
Courtroom & hearing room
The failure mode. Hard surfaces, no acoustic treatment, and a record
that must be complete. Feedback appears the moment gain is raised to reach the gallery, and a
single dropped channel can make a session unusable as evidence.
What we deploy. Chairman and delegate units with automatic speaker
muting and internal howling suppression, a wireless lavalier for the witness position, two PTZ
cameras, and a recording host writing both the directed programme and every isolated channel.
What we check first. Reverberation time, gallery depth, whether the
bench position can take a fixed unit, and how the recording is expected to be archived and
retrieved months later.

ROOM B
Council chamber & assembly
The failure mode. Many seats, contested speaking order, and a public
that expects to watch. Meetings overrun because nobody can control the floor, and the stream is an
afterthought bolted on with a laptop.
What we deploy. A conference chain in request-to-speak or FIFO mode
with chairman priority, cameras on preset per seat block, and native RTMP or HLS publishing from
the recording host — no external encoder and no laptop in the loop.
What we check first. Seat count and table geometry, whether members
need individual monitoring, and the upstream bandwidth actually available at the building.

ROOM C
Lecture theatre & training room
The failure mode. The presenter moves, the slides matter as much as
the speaker, and the recording is worthless if only one of the two was captured. Back rows lose
intelligibility long before they lose level.
What we deploy. Wireless lavalier for the presenter, a camera on the
stage with recall presets, the presentation feed taken directly as an HDMI input, and composite
recording so the finished file shows both. Distributed wall loudspeakers rather than a single
front pair.
What we check first. Ceiling height, room depth, whether the lectern
is fixed, and whether the recording will be published or archived.

ROOM D
Command & control room
The failure mode. Continuous duty. Consumer-grade equipment fails at
the fan, the disk or the power supply somewhere in the second year, and a recorder that stops
silently is worse than no recorder at all.
What we deploy. An embedded Linux recording platform with no moving
parts except a hot-swappable surveillance-grade disk, one-key system recovery and abnormal file
repair, driven from a single multi-protocol keyboard that can address a mixed camera fleet.
What we check first. Rack ventilation, UPS holdover, retention period
required, and whether existing third-party cameras must be controlled from the same desk.

ROOM E
Community & assembly hall
The failure mode. Whoever is on duty operates it. A system with a
learning curve will be used wrongly, then abandoned, then declared broken.
What we deploy. A single mixer amplifier with front-panel zone
switching and clearly legended level controls, wall plates so each area sets its own level, and
priority ducking so an announcement always cuts through the background programme automatically.
What we check first. Who will actually operate it, how many separate
areas need independent level, and whether background music is expected from Bluetooth, USB or tuner.

ROOM F
Campus & municipal public address
The failure mode. Long cable runs across buildings, zones added over
years by different contractors, and an amplifier that has quietly been overloaded since the last
extension.
What we deploy. Constant-voltage distribution at 100 V with tap
selection at each loudspeaker, so zones can be added or rebalanced without recalculating impedance,
and five separately switchable zones per amplifier for staged announcements.
What we check first. Total connected tap power against amplifier
rating, cable gauge and run length, and whether emergency announcement priority is required.
