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.

01 / Host integration

Connect an existing platform.

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.

02 / Device development

Build an application on the device.

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.

From reference to a working exchange.

  1. Identify the configuration

    Send the model, firmware version, selected interfaces and the system you want to connect.

  2. Describe one complete interaction

    For example: read a credential, validate it in your platform, return a result and record the event. Include required offline behaviour.

  3. Test with the matching reference

    Review the applicable protocol or SDK, then validate commands, responses, errors and recovery on an evaluation device.

Common questions for FCC4904.

Does every configuration include the same features?

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.

Is a network connection the same as a connection to the management platform?

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.

Why might a successful credential check not open the door?

Identity verification, access permission and the physical control output are separate parts of the workflow. Have a qualified installer check the operating mode, permission result, relay timing, controller output and lock wiring against the installation instructions.

What should I share when choosing a device?

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.

How can I get a manual or datasheet?

Find available documents by model in the download center. If the manual, specification or installation drawing you need is not listed, send the model and configuration to our team so we can identify the matching document.
