| Incoming components | Incoming inspection can check component identity, quantity, visible damage, and specified electrical or mechanical characteristics before assembly. | Component selection may be tailored to the agreed design, such as camera, display, microphone, speaker, or enclosure requirements. | Inspection criteria, component specifications, and traceability records where maintained. |
| Assembly and workmanship | In-process checks can verify assembly steps, wiring, connectors, fasteners, and visual workmanship against documented requirements. | Housing materials, colors, button layouts, labels, and mounting arrangements can be specified for a project. | Work instructions, inspection checklists, and approved product drawings or samples. |
| Audio and video function | Functional tests can check camera output, display operation, two-way audio, door-release signaling, and controls included in the product specification. | Screen size, camera resolution, viewing angle, audio features, and user-interface language can be defined according to the intended use. | A test plan with pass criteria and recorded results for the agreed functions. |
| Connectivity and compatibility | Testing can confirm the selected wired or wireless connection, network setup, and compatibility with specified indoor stations or accessories. | Connection type, network features, integration interfaces, and accessory combinations can be agreed during design. | Compatibility list, interface specifications, and results from tests using the agreed system configuration. |
| Environmental protection | If an ingress-protection rating is claimed, verify it against the applicable test report and the conditions covered by that rating. IEC 60529 defines IP enclosure classification. | Enclosure design, seals, and installation accessories can be specified for the intended indoor or outdoor installation conditions. | Applicable test reports, installation instructions, and the exact rating claimed for the model. |
| Safety and compliance | Safety and regulatory requirements depend on the product design and destination market. IEC 62368-1 covers safety requirements for certain audio/video and information and communication technology equipment. | Power supply, plugs, markings, manuals, and packaging can be adapted to destination-market requirements, subject to verification. | Applicable declarations, certificates, or test reports for the specific model and market. |
| Final inspection and packaging | A final check can confirm appearance, core functions, included accessories, labeling, and packaging against the approved order specification. | Packaging format, printed materials, language, labels, and accessory kits can be defined for the project. | Final inspection records, approved artwork, packing list, and a pre-production sample where appropriate. |
| Quality-system management | A documented quality-management system supports defined processes, corrective action, and continual improvement. ISO 9001 specifies requirements for quality-management systems. | Project-specific specifications, approval stages, and change-control procedures can be agreed before production. | Current system documentation or certification evidence, plus a clear process for handling design and production changes. |
