## 1. FAQ

<AccordionGroup>
  <Accordion id="q1" title="1.1 Why can the embedded page be accessed on some devices but not others?">
    This usually happens because the embedded page uses the HTTP protocol, while the YiDA platform uses HTTPS.

    For security reasons, browsers restrict this kind of embedding. Some Android devices with more lenient security policies may still allow access, but most newer devices and browsers block such requests.

    **To resolve this issue, embed a URL that uses the HTTPS protocol.**
  </Accordion>

  <Accordion id="q2" title="1.2 Does the YiDA platform support video data integration, such as connecting an external camera and displaying its feed on the YiDA platform?">
    Yes. Use the Iframe component to embed a live camera feed link.

    Add the Iframe component to a custom page, then configure the camera feed link in the Attribute panel on the right.
  </Accordion>

  <Accordion id="q3" title="1.3 Does it support Alibaba Cloud VOD (Video on Demand) service? The scenario is providing customers with a video window to remotely monitor crop growth.">
    The Iframe component only embeds third-party pages. YiDA acts solely as the display endpoint. If the third-party page supports on-demand streaming, then on-demand streaming works.
  </Accordion>

  <Accordion id="q4" title="1.4 The HTML component configured on a custom page does not execute JavaScript as expected. Does the HTML component not support importing JS files?">
    JavaScript can be executed, but it must be imported inside `didmount()`.
