Let’s work through it.

Include the overseas product model, firmware or software version, connection method and a short sequence that reproduces the issue. Screenshots, indicator behavior and relevant logs help; do not send passwords, access credentials or personal biometric data.

Compare the power supply voltage, current capacity and wiring with the specification for the selected configuration. If the problem continues, record whether it happens at startup or during a particular action and send the model, firmware and observations to technical support.

No. Confirm door material, thickness, handedness, existing holes, backset and lock-body requirements before selecting a configuration. Photographs of both sides and the door edge, together with measurements, are more useful than a front view alone.

Tell us who issues access, which credentials are planned, how permissions are updated, the expected offline behavior and how the door is prepared. Credential, gateway and management capabilities depend on the selected configuration and must be confirmed together.

Tell us which credentials people will use, where the device will be installed, which interfaces are required and what should happen in the software workflow. A mounting drawing, host-equipment description or simple process diagram helps us identify the questions that must be confirmed before recommending a configuration.
