Understand your requirements
We review your application, product questions and the context you share.
Let’s build
what comes next.
Find the right hardware, connect your software, or shape a device around your application.
Our team will review your requirements and contact you as soon as possible.
Our team is based in China (UTC+8).
Start with the right device.
Discuss credentials, interfaces and installation with the people behind the product.
Connect the whole workflow.
Bring your platform requirements and the experience you want to create on the device.
Make room for your ideas.
Explore hardware, software and DejaOS development around a clear project brief.

Tell us about your project.
A product question, an integration challenge, or an idea to develop. Start here.
What happens next.
Confirm the direction
We discuss the device, configuration or development work that needs evaluating.
Agree on the next step
Together, we identify the information, technical discussion or sample evaluation needed.
Before you get in touch.
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.
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.
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.
How should we evaluate a product for our project?
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.
What should I include in a technical support request?
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.
What should we check if a device repeatedly restarts?
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.
