Dahua LPH75-MT440-C 75″ UHD Smart Interactive Whiteboard
The Dahua LPH75-MT440-C Smart Interactive Whiteboard is designed to enhance collaboration in modern meeting rooms, classrooms, command centers, and other professional environments. Built with Android 8.0 and powered by a quad-core CPU and GPU architecture with 4 GB RAM and 32 GB storage, the system provides strong processing performance for presentations, content management, and interactive collaboration.
Equipped with a high-precision infrared touch frame featuring a 2 mm identification diameter and a 4K high-definition DLED display module, the whiteboard delivers a responsive and accurate interactive experience. Whether users are writing, controlling applications, or displaying content, the system provides smooth operation and vivid visual clarity.
The smart interactive whiteboard integrates a wide range of collaboration tools including wireless screen sharing, video conferencing, file management, HD display, and scan-and-share features. These capabilities help modernize meeting spaces and improve the efficiency of presentations and discussions.
4K Camera with Ultra-Wide Field of View
The built-in 8-MP camera supports a maximum resolution of 4K at 30 fps and features an ultra-wide field of view with diagonal 112.7°, horizontal 104°, and vertical 70.2°. This wide coverage captures clear images across larger meeting spaces while maintaining vivid visual detail for video conferencing.
Hidden Antenna Design
The Wi-Fi and hotspot antennas feature a front hidden design that maintains a clean and modern appearance. This design also helps ensure stable wireless signal strength even when the whiteboard is installed using a flush wall mount.
Advanced Wireless Screen Sharing
The whiteboard supports wireless screen sharing with a range of collaboration features including basic file sharing, reverse control, and screen grouping for multiple simultaneous transmissions. Users can also transmit wireless camera images and sound from mobile devices in real time.
Host mode allows centralized meeting control while split-screen mode can display up to nine different screens simultaneously, enabling multiple participants to present and collaborate at the same time.
Real Writing Experience
The smart interactive whiteboard supports tilt-sensitive writing and includes specialized pressure-sensitive stylus pens designed to provide a natural writing experience. With its soft and comfortable pen nib, writing on the display feels smooth and closely resembles writing on paper.
Strong System Security
The system supports multiple authentication methods including digital password, gesture password, and fingerprint password. These security methods can be applied to screen unlocking, USB permissions, touch lock, and factory restore settings.
Up to 256 fingerprint passwords can be registered with a fingerprint resolution of 508 DPI. The system provides strong security performance with a false acceptance rate below 0.001% and a false rejection rate below 0.1%.
Easy File Sharing with QR Code
File sharing is simplified through a QR code-based sharing system. The device automatically determines the network environment and generates a QR code that can be shared across both intranet and extranet networks.
Additional protection is provided through QR code encryption and extraction features that require a six-digit randomly generated verification password before files can be accessed.
Ideal for Professional Environments
The Dahua Smart Interactive Whiteboard is suitable for indoor environments such as meeting rooms, command centers, hospitals, banks, and other professional settings where efficient collaboration and digital communication are required.
