| Wireless Protocol Compatibility | At least one mature protocol such as Bluetooth Low Energy, Wi-Fi, Zigbee, Z-Wave, NFC, or Thread; gateway options should be clearly documented. | Protocol specification, supported profiles, interoperability test results, and gateway architecture diagram. | 15% | Determines installation flexibility, system compatibility, range, power use, and future expansion. |
| Security Architecture | Encrypted communication, secure credential storage, role-based access control, audit logs, firmware signing, and documented vulnerability handling. | Security white paper, encryption details, penetration-test summary, secure-boot statement, and vulnerability disclosure policy. | 18% | Wireless locks control physical access, so protection against cloning, replay, unauthorized entry, and data exposure is essential. |
| Mechanical Durability | Performance should be supported by applicable ANSI/BHMA, EN, or equivalent regional testing; commercial projects should specify cycle and load requirements. | Independent test reports, cycle-test results, load ratings, latch/bolt specifications, and material declarations. | 14% | A strong wireless platform cannot compensate for premature wear, misalignment, or mechanical failure. |
| Environmental Protection | Indoor and outdoor models should have a clearly stated IP rating; outdoor installations commonly require protection against dust and water exposure appropriate to the site. | IP test report, operating-temperature range, humidity limits, corrosion-resistance data, and installation instructions. | 8% | Moisture, dust, temperature variation, and salt air can affect electronics, batteries, seals, and mechanical components. |
| Battery and Emergency Access | Low-battery alerts, predictable battery replacement, mechanical or external emergency override, and documented battery-life test conditions. | Battery-life test protocol, alert screenshots, emergency-access procedure, battery compatibility, and low-power behavior. | 10% | Power loss must not create unsafe lockouts or an uncontrolled security condition. |
| Software and Cloud Management | Centralized user management, time-limited credentials, event logs, remote configuration, API documentation, and a defined software-support lifecycle. | Live software demonstration, API documentation, data-retention policy, update schedule, and service-level terms. | 12% | Management quality affects operating cost, security visibility, integration, and scalability across sites. |
| Compliance and Certifications | Applicable electrical, radio, safety, privacy, and market-entry requirements must be identified for the destination country or region. | Current certificates, declarations of conformity, laboratory reports, radio approvals, and product traceability records. | 8% | Compliance documentation reduces customs, legal, insurance, and deployment risks. |
| OEM, ODM, and Integration Capability | Documented customization process for firmware, housing, credential workflows, packaging, languages, and third-party integrations. | Sample customization agreement, development timeline, interface specifications, pilot plan, and change-control procedure. | 6% | Useful for projects requiring local standards, specialized access policies, or integration with existing platforms. |
| Quality Control and Traceability | Incoming-material inspection, in-process testing, final functional testing, serial-number traceability, and corrective-action records. | Quality manual, inspection checklist, sample test records, batch traceability process, and nonconformance report example. | 5% | Consistent production quality is especially important for large deployments and replacement-part planning. |
| After-Sales Support and Spare Parts | Defined warranty terms, technical support channels, replacement-part availability, firmware support, and escalation procedures. | Warranty policy, response-time commitments, spare-parts list, service network details, and end-of-life notification policy. | 4% | Long-term serviceability can have a larger effect on total cost than the initial purchase price. |
