Feocey Open API is the starting point for device integration guidance. Protocols and references are matched to the hardware, firmware and application; there is no single public endpoint catalogue covering every model.
Your access, attendance or visitor platform exchanges commands and events with the selected device. Start with the required data, connection method and device firmware.
Face terminals, QR readers and controllers use different interfaces and message formats. An Ethernet or RS485 connection alone does not define the API.
On supported DejaOS models, develop the device interface and behaviour in JavaScript. Match the SDK and available modules to the selected hardware configuration.
The DejaOS documentation describes device application development. A project’s host protocol and service credentials are separate parts of the integration.
Read DejaOS documentation ↗Send the model, firmware version, selected interfaces and the system you want to connect.
For example: read a credential, validate it in your platform, return a result and record the event. Include required offline behaviour.
Review the applicable protocol or SDK, then validate commands, responses, errors and recovery on an evaluation device.

The source manual uses the DW200 hardware designation. Match the reader or access-control version before wiring.

The source filename says READER, while its diagrams include access-control connections. Use it only after matching the exact terminal version and harness.
No. Select the reader or access-control configuration first. Exit-switch and door-contact inputs and relay output apply to the access-control configuration. Match the supplied harness and firmware to the connection reference; a shared model family does not make every version interchangeable.
Do not assume so. Reader firmware and access-control firmware can use different tools, configuration codes or platform commands. Share the overseas model, firmware and intended operating mode so the matching method can be checked before changing settings.
No. A device can have local network access without maintaining its platform or messaging connection. Check the physical network, IP settings and service connection separately, using the indicators or logs available for the selected system.
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.
No. Credential modules, interfaces, mounting parts, network options and software can vary within the same product family. Confirm the exact model and selected options in writing before designing an enclosure, cable set or integration around it.
