Commission against an approved design, not memory
Commissioning should begin with the latest approved drawings, equipment schedule, cable schedule, control narrative, network requirements, and room-by-room scope. The commissioning lead should confirm that revision numbers match what installers used on site. If the rack elevation, display model, or touch-panel logic changed during construction, update the test plan before signing anything.
Create one checklist for each room type and one asset list for the whole project. Record room name, device serial numbers, firmware versions, IP addresses where appropriate, cable labels, rack positions, and the drawing revision used for testing. This makes the result repeatable and gives support teams a baseline after the project team leaves.
A qualified [AV integrator in China](https://sinoway.asia) can coordinate these checks with the local contractor, client IT team, furniture installer, and overseas stakeholders without treating commissioning as a last-minute demonstration.
Complete safety and pre-power checks first
Before energizing a rack or room, inspect power distribution, earthing, ventilation, equipment clearances, cable strain relief, connector termination, rack labeling, and service access. Confirm that the installed voltage and outlet arrangements match the specified equipment. Check that fans and vents are unobstructed and that cable bundles do not restrict future maintenance.
Trace the main signal paths against the drawings. A cable passing continuity is not enough if it is connected to the wrong input or labeled inconsistently at each end. Photograph rack fronts, rack rears, floor boxes, ceiling devices, and concealed connection points before panels are closed. These images become useful evidence when a fault appears months later.
Do not power the whole system at once simply to see what happens. Use a planned sequence, watch for abnormal current draw, noise, heat, or boot failures, and stop when a condition differs from the approved design.
Test every signal path in both directions
A successful source-to-display test proves only one route. Commission all expected routes: room PC to local display, wireless presentation to both displays, videoconference content to the far end, far-end content to the room, microphone audio to local reinforcement where designed, and program audio to the correct loudspeakers. If a room can be combined or divided, test each physical configuration.
Use known-good test material for resolution, color, motion, audio channels, and lip synchronization. Confirm that displays wake, switch, and sleep as intended; that muted states are visible; and that a user cannot accidentally send private content to the wrong screen. Test HDMI, USB-C, USB peripherals, networked AV, and wireless paths separately rather than assuming one successful route validates the rest.
For divisible spaces, follow the room-combining sequence described in the design narrative. The practical issues and acceptance points are also covered in Sinoway's guide to [divisible training room AV systems](https://www.sinoway.asia/blog/divisible-training-room-av-system-china).
Coordinate AV and network validation
Modern meeting rooms often depend on corporate networks for conferencing, device management, control, monitoring, wireless presentation, or audio and video transport. The AV team should not guess network settings or bypass security controls to make a temporary test succeed.
Agree with IT on VLANs, switch ports, addressing, DHCP reservations, DNS, time synchronization, firewall rules, quality-of-service policies, and any required cloud service access. Verify that device names are meaningful and that credentials are transferred securely to the authorized owner. Document which settings belong to the AV integrator and which remain under client IT control.
Test after the final production switch configuration is applied. A room that works on an isolated commissioning switch may fail when moved to the corporate network. Where networked AV is used, check stream discovery, multicast behavior, clocking, bandwidth, and recovery after a switch restart. Record results rather than relying on a screenshot of a green dashboard.
Run real meeting workflows, not isolated button tests
Button-by-button testing can miss failures that appear only during a real meeting. Build short scenarios that resemble normal use: start a local presentation, join a video call, share content, mute and unmute, adjust volume, switch presenters, end the call, and return the room to its ready state. Test both scheduled and ad hoc meetings if both are supported.
Include a laptop that has not previously used the room. Check camera framing, microphone pickup, echo, speech intelligibility, content legibility from the farthest seat, and whether on-screen instructions match the installed connections. Ask someone unfamiliar with the project to complete the core workflow without coaching. Their hesitation often reveals unclear labels or control language.
The goal is not to prove that every device turns on. It is to prove that an ordinary employee can complete the intended task reliably.
Measure, record, and close the punch list
Where the design specifies measurable performance, use appropriate instruments and record the result. Examples can include display resolution, image alignment, audio level, signal latency, wireless coverage, cable certification, and network statistics. Do not substitute a subjective “looks fine” or “sounds fine” when the acceptance requirement is quantitative.
Log every defect with a room, device, description, severity, owner, target date, and evidence. Separate issues that block acceptance from cosmetic or low-priority items. After correction, retest the affected workflow and any related functions that could have changed. Marking an item closed without retesting creates uncertainty for the client and the service team.
The difference between proactive verification and waiting for user complaints is explored in [preventive AV maintenance versus break-fix support](https://www.sinoway.asia/blog/preventive-av-maintenance-vs-break-fix-support-china). Commissioning provides the first reliable baseline for that future maintenance.
Prepare a usable handover and acceptance gate
The final package should reflect the installed system, not only the tender design. Include as-built schematics, floor plans, rack elevations, cable schedules, equipment inventory, serial numbers, firmware records, approved network details, configuration backups, warranties, support contacts, commissioning results, open exceptions, and safe shutdown or restart instructions.
Use consistent filenames and dates. Store editable source files as well as review PDFs when appropriate. Identify which documents contain sensitive network or credential information and restrict them accordingly. Provide a clear owner for each master file so future technicians do not update several conflicting copies.
Handover should include training for local facilities, IT, and workplace teams. Cover everyday use, first-line checks, escalation, cleaning and maintenance constraints, and what information to collect when reporting a fault. A short room quick-start guide is useful, but it does not replace technical records.
A room is ready for acceptance when the agreed scope is installed, critical workflows pass, network dependencies are approved, the punch list has no unresolved blockers, documentation is delivered, configurations are backed up, and responsible teams have completed training. If the client accepts minor open items, record them with owners and dates in the signed exception list.
Schedule final acceptance when furniture, lighting, acoustic treatments, the production network, and normal room conditions are in place. The signed checklist should identify exactly what was tested, when it was tested, who witnessed it, and which revision of the design it represents.
Frequently asked questions
What is included in AV commissioning?
AV commissioning normally includes design and installation checks, power-up, signal-path testing, control testing, network coordination, real meeting scenarios, measurement, defect tracking, documentation, training, and signed acceptance.
When should office AV commissioning begin?
Planning should begin during design, while physical checks start before power-on. Final acceptance testing should occur after the room, furniture, lighting, acoustics, and production network are substantially complete.
Who should witness AV acceptance in China?
Common witnesses include the client project lead, local IT or facilities representatives, the AV integrator, relevant contractors, and an overseas stakeholder when corporate standards require it.
Can a room be accepted with open issues?
Minor issues may be accepted only when documented with an owner, deadline, and agreed impact. Failures affecting safety, core workflows, security, or contractual performance should remain blockers until corrected and retested.
