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.

For FCC4901, FCC4904
Shared table for single-door and four-door versions. Confirm variant, chassis dimensions and capacity before ordering or installation.
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.
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.
Start with the credential, mounting, interfaces and software flow that matter to the final installation. Confirm the sample configuration in writing, test it in the intended environment and record any differences before planning a larger rollout.
Not necessarily. Identity enrollment and access permission are separate steps in many systems. Confirm that the person, credential, target device, schedule and permission group have been linked and that the authorization was delivered successfully.
