How to assess camera coverage in a TB-ML 3000 meeting booth

To assess camera coverage in a TB-ML 3000 Multiple Person Meeting Booth, test every intended seat through the actual conferencing connection, with the furniture installed and the door closed. A usable setup keeps faces recognizable during normal movement, avoids persistent obstructions, and limits views of activity outside the enclosure. An empty-booth preview or a camera’s advertised viewing angle cannot establish those conditions.

Begin with the proposed seating layout, camera position, display, and meeting software. Record the configuration before adjusting anything: a change in mounting height or digital framing can resolve one blind spot while creating another. Coverage is acceptable only when the arrangement works across the occupied seats and the meeting modes that will actually be used.

Establish the space the camera must cover

Use the installed internal dimensions or a verified layout drawing for the specific booth. The TB-ML 3000 model designation alone does not establish camera distance, table geometry, glazing position, or seating capacity. Measure from the proposed camera lens position to the nearest and farthest seated face positions, then record the lateral spread of the seats.

Include the space occupied when chairs move backward, participants lean toward the table, or someone turns toward the display. Seat centers alone underestimate the required framing envelope. Identify whether the intended view needs faces and shoulders, upper bodies, or table activity; each requirement changes the necessary vertical coverage.

Dimensions from another pod should remain separate from this assessment. For example, the TB-W Office Pod 1-2 Person has stated internal dimensions of W1350 mm × D1200 mm × H2000 mm. Those measurements describe a different enclosure and cannot establish mounting clearances or camera coverage in the TB-ML 3000.

Translate the lens specification into usable framing

Confirm whether the published field of view is horizontal, vertical, or diagonal. A diagonal figure does not directly describe the width available across a row of seats. Also confirm that the figure applies to the selected resolution and camera mode: digital stabilization, distortion correction, and automatic framing can reduce the delivered view.

For an initial geometric estimate, a centered, rectilinear camera covers a width of 2 × distance × tan(horizontal field of view ÷ 2) on a plane perpendicular to its viewing direction. Use the distance from the lens to the face plane being evaluated. This calculation helps screen proposed positions, but wide-angle distortion, an angled mount, and seats at different depths require verification in the live image.

The nearest seats often determine whether the horizontal view is wide enough. The farthest seats introduce a different constraint: faces occupy fewer pixels. A camera can include everyone while delivering insufficient facial detail at the back of the booth. Digital zoom enlarges the captured image without restoring missing detail.

Open a call on a remote device and assess the received picture at a normal viewing size. A local preview can differ from what the meeting platform transmits. Repeat the assessment while screen sharing, because the reduced video tile can make distant faces harder to recognize.

Resolve mounting position and obstructions together

A position near the display centerline is a useful starting point because participants looking at remote colleagues will look close to the camera. A high mount increases the downward angle and can make near participants dominate the frame. A low mount can leave faces hidden behind laptop screens or foreground objects.

Temporarily position the camera before fixing the bracket. Use a stable support outside the circulation path, then compare plausible heights and tilt angles. Evaluate the lens position itself; the bracket location is only a reference for installation. Confirm that the final mounting method is suitable for the panel construction and avoids concealed wiring and ventilation paths.

Place the objects expected during meetings on the table. Laptop screens, a central monitor, bottles, and presentation materials change sightlines. With seats arranged along both sides of a table, a nearby participant can also obscure someone farther away. A wider lens will not resolve an obstruction along the same line of sight.

If overlapping faces persist, test a lateral camera adjustment or a revised chair position. Where one camera cannot cover the required layout, assess whether an additional view is supported by the conferencing system and whether switching between views preserves a coherent meeting experience.

Test occupied seats under normal movement

Use people in the intended seats for the final assessment. Empty chairs reveal the furniture layout but do not reproduce face height, shoulder width, posture, or obstruction by adjacent participants. Include the expected range of seated heights and adjust chairs within their intended operating range.

1. Start with a fixed wide view and automatic framing disabled. Capture the occupied layout to establish whether the underlying camera position covers every seat.
2. Have participants speak from each seat, turn toward the display, lean back, and use their laptops. Observe clipped heads, overlapping faces, and movement beyond the image edges.
3. Enable the intended tracking or framing mode. Follow a conversation between opposite seats, including interruptions and quiet listeners.
4. Test entry and exit through the door. Observe whether tracking follows a departing person or exposes the corridor before returning to the meeting.

Allow each scene to settle before judging the result. Automatic framing introduces behavior that a still image cannot reveal: delayed expansion, frequent reframing, or close views that exclude listeners. Record which function causes the failure so that a software setting is not confused with a mounting problem.

Assess glass, lighting, and the outside view

Review glazing from the camera’s exact position. Transparent panels can reveal people, screens, or movement beyond the booth, while reflections can introduce a second view of the interior or surrounding office. Test both with the external area illuminated and with the booth lighting at its intended meeting setting.

A bright background can cause automatic exposure to darken faces. Increasing interior brightness helps only when the light reaches faces without introducing glare. Compare frontal illumination, overhead shadows, and reflections from laptop screens. Change lighting and camera angle separately so the effect of each adjustment remains clear.

Inspect the transmitted video for flicker or moving bands, especially after dimming the lights. These artifacts can result from the interaction between lighting control and camera exposure. Test compatible exposure or anti-flicker settings and retain a combination that works throughout the planned lighting range.

For privacy, distinguish between an optical restriction, a crop applied by the camera, and a background effect applied by the meeting application. Software blur is not a dependable visual boundary: tracking errors, movement, or changes in framing can expose the background. Where activity outside must remain unseen, test physical screening or a camera position that excludes the relevant glazing.

Define acceptance around observable results

Set acceptance criteria before selecting the final configuration. Every intended seat should retain a complete face during agreed normal movements; laptops should not create persistent facial obstruction; and distant participants should remain recognizable in the received call. Define the exterior areas that must remain outside the transmitted view, including during automatic reframing and door movement.

Keep a short record of the accepted mounting position, lens height, tilt, resolution, framing settings, lighting state, and furniture arrangement. Attach representative received-video captures for the nearest seat, farthest seat, and most obstructed position. Record any restrictions, such as a laptop placement limit or a tracking mode that must remain disabled.

After permanent installation, repeat the occupied-seat test through the production meeting connection. Small differences in bracket position or the camera mode restored after a restart can change framing. Approval should apply to the tested configuration, with reassessment when seating, displays, camera settings, or glazing treatments change.
