3. Product Advantages

• (1) Full-Terminal Compatibility, No Threshold for Screen Mirroring
  Covers mainstream operating systems including Windows, MAC, Android, and iOS. It supports hardware transmitters (USB/HDMI/TYPE-C, no software installation required) and software mirroring (AirPlay/Miracast/WIN Sender). Whether it is a computer, mobile phone, or tablet, quick connection is achievable, eliminating device compatibility issues.
• (2) High-Speed & Low-Latency, Stable Transmission
  Adopting 5G/2.4G dual-band WiFi modules, the wireless transmission speed reaches up to 867Mbps with an average latency of less than 100ms. Stable transmission is ensured within 15m line-of-sight without obstruction. Equipped with 4K input + 1080P output and 30fps frame rate, the mirrored screen is clear and smooth without lag or ghosting, meeting high-definition demonstration needs.
• (3) Comprehensive Functions, More Efficient Conferences
  Supports touch backhaul (compatible with all screen mirroring methods), allowing direct touch operation on the source device via the mirrored screen; supports extended desktop mirroring to realize split-screen collaboration of "main screen demonstration + secondary screen operation"; can access 8 devices simultaneously, with no waiting time for switching screen mirroring. Combined with screen mirroring code verification, it ensures the security of conference content.
• (4) Flexible Management, Strong Scene Adaptability
  Supports arbitrary combination of three access methods: AP, wired, and wireless network card, adapting to different network environments; provides a WEB management interface and centralized control software, enabling batch modification of parameters such as WiFi name, video resolution, and channel; supports custom boot/standby screens to fit the corporate brand image.

4.สถานการณ์การใช้งาน

• (1) Corporate Conference Scenarios

  Suitable for small and medium-sized meeting rooms. Participants can quickly mirror screens to demonstrate plans via mobile phones and laptops. The touch backhaul function allows direct annotation and modification of documents on the large screen, eliminating the need for frequent switching of operating devices, shortening conference discussion time, and improving decision-making efficiency.

• (2) Education & Training Scenarios

  Teachers can mirror courseware via tablets, and students can mirror homework via computers. It supports extended desktops to realize simultaneous "courseware explanation + note-taking"; 15m long-distance transmission is suitable for large classrooms, ensuring stable screen mirroring for devices in the back row and enhancing classroom interactivity.

• (3) Government & Business Negotiation Scenarios

  Supports screen mirroring code verification to prevent unauthorized device access and ensure the security of government data and business information; the boot screen can be customized with corporate/government logos to enhance the professionalism of the scenario. Meanwhile, 7×24-hour stable operation meets the needs of long-term negotiations.

5. Usage Instructions

Device Connection: Power the system via a 12V1A power adapter, connect the screen mirroring system to a display device (such as a projector or conference screen) using an HDMI cable, and connect to a network cable (for wired bridging) or rely on wireless WiFi as needed.

Screen Mirroring Operation:

• Hardware Mirroring: Insert the USB/HDMI/TYPE-C transmitter into the source device (computer/mobile phone) and trigger screen mirroring with one click;
• Software Mirroring: Open the WIN Sender software on Windows devices, and search for the device name via AirPlay/Miracast on iOS/Android devices to connect.

Parameter Setting: Enter the device IP in a browser to access the WEB management interface, where you can modify the WiFi name/password, video output resolution, channel, etc., and customize the boot/standby screen.

Precautions: Ensure no obstruction between the transmitter and the host during wireless screen mirroring, and the distance does not exceed 15m; the touch backhaul function requires the source device to be connected to the screen mirroring system via USB/HDMI/TYPE-C; avoid long-term use in high-temperature (>40°C) or high-humidity (>90%RH) environments.
