| 1 | Product Portfolio | Availability of audio intercoms, video door phones, apartment systems, villa systems, access-control terminals, indoor monitors and management software. | At least 3 compatible system configurations for the intended project type. | Current product catalogue, technical datasheets and system architecture diagrams. | A broader portfolio reduces integration risks and makes future expansion easier. |
| 2 | Communication Protocols | Support for SIP-based communication, TCP/IP networking, RTSP video streaming or other open interfaces where required. | Open protocols documented in writing; avoid systems that depend entirely on undocumented interfaces. | Protocol manuals, API documentation and a live interoperability test. | Open interfaces improve compatibility with PBX, building-management and security platforms. |
| 3 | Network and Power Design | Ethernet connectivity, Power over Ethernet compatibility, local power input, network topology and backup-power options. | Confirm compatibility with IEEE 802.3af or IEEE 802.3at when PoE is specified for the project. | Power budget, wiring diagram, PoE declaration and installation instructions. | Correct power planning helps prevent voltage drops, random reboots and costly rewiring. |
| 4 | Outdoor Protection | Ingress protection, operating temperature, impact resistance, drainage design and suitability for exposed entrances. | Use an enclosure rating appropriate to the site; IP65 is a common target for exposed equipment, subject to installation conditions. | Test reports, enclosure rating documentation and environmental specifications. | Outdoor door stations face rain, dust, temperature changes and repeated physical use. |
| 5 | Access Methods | Support for PIN codes, RFID credentials, mobile access, QR codes, biometric options and exit buttons. | At least two independent access methods plus a mechanical or electrical emergency-release procedure. | Credential compatibility list, security settings and emergency-operation procedure. | Multiple access methods improve convenience and provide operational redundancy. |
| 6 | Security and Data Protection | Administrator roles, encrypted communication, password policy, audit logs, firmware controls and data-retention settings. | Individual administrator accounts, role-based permissions, encrypted remote access and exportable event logs. | Cybersecurity statement, privacy documentation, update policy and sample audit log. | Door-entry systems process access events and may handle personal or video data. |
| 7 | Standards and Market Compliance | Applicable electrical, electromagnetic-compatibility, radio, safety and environmental requirements for the destination market. | Documentation must match the final model, hardware revision and destination country; do not rely only on a general certificate. | Declarations of conformity, test reports, labels and applicable regional approvals. | Correct compliance documentation supports customs clearance, installation approval and buyer acceptance. |
| 8 | Customization Capability | Logo or interface customization, language packs, relay configuration, enclosure changes, firmware settings and API integration. | Written confirmation of what is standard, configurable, chargeable or subject to a minimum order quantity. | Customization checklist, engineering-change process and approved sample. | Clear customization rules reduce misunderstandings about appearance, function and delivery time. |
| 9 | Quality Control and Testing | Incoming inspection, assembly inspection, functional testing, network testing, burn-in testing and traceability. | Require documented inspection criteria and a pre-shipment inspection plan for every production batch. | Quality manual, inspection records, test checklist and sample serial-number traceability. | Structured testing is more reliable than evaluating quality only from a product sample. |
| 10 | After-Sales and Supply Continuity | Warranty terms, spare parts, firmware support, remote troubleshooting, replacement policy and product-lifecycle planning. | Obtain written warranty coverage, response times, spare-parts availability and an end-of-life notification process. | Warranty document, service-level terms, support contacts and product-lifecycle statement. | Long-term support is essential because installed door-entry equipment can remain in service for years. |
