What Remote Teaching and Online Education Solutions Does VHD ODM Offer?
As an A-share listed audio/video ODM manufacturer, VHD provides a complete product matrix for remote teaching and online education scenarios—from education-specific cameras (JX1811K, JX200I, VX800I2) and education microphones (M702C, M710T) to non-wearable sound reinforcement solutions (M800, M800Pro), plus a full range of PTZ cameras and audio devices. VHD offers both standardized solutions and customized development.
I. Characteristics of Remote Teaching and Online Education Scenarios
Audio/video requirements in the education sector differ from those of ordinary meeting rooms, with distinct characteristics:
1. High Image Requirements: Both the Teacher and the Whiteboard Must Be Clear
- Teachers move around, write on whiteboards, and demonstrate experiments.
- Students must clearly see the teacher’s expressions, whiteboard handwriting, and experiment details.
- Ordinary fixed-focus cameras either cannot capture the full scene or cannot capture it clearly; intelligent tracking and zoom capability are required.
2. Audio Is Critical: Clear Sound Without Feedback
- Teachers speak while moving; microphones cannot be fixed in only one position.
- Classrooms have echo, students turning pages, and outside noise; strong noise reduction is required.
- Sound reinforcement must not cause feedback—if the teacher approaches the speaker and the sound becomes piercing, the class cannot proceed.
3. Equipment Must Be Stable: No Failures During Class
- A class lasts 45 minutes; equipment failure mid-session disrupts the entire teaching schedule.
- Equipment must be durable and reliable, not frequently failing.
- O&M must be simple—school IT staffing is limited, and overly complex equipment is impractical.
4. Diverse Scenarios: Not Just Lecture Recording
- Dual-teacher classrooms: one teacher instructs multiple classes.
- Dedicated delivery classrooms: quality educational resources delivered to under-resourced schools.
- Online education: live classes, recorded classes, and interactive teaching.
- Campus TV stations: student practice and campus event live streaming.
- Teaching research meetings: cross-school teaching research and teacher training.
In short, education scenarios require audio/video equipment that delivers: strong image quality, clear audio, high stability, and easy maintenance.
II. Remote Teaching Cameras: Designed for Education Scenarios
VHD offers multiple education-specific cameras covering different budgets and requirements:
JX1811K — 4K Intelligent Tracking Camera
The JX1811K is a 4K intelligent teaching tracking camera designed for dual-teacher classrooms, dedicated delivery classrooms, interactive teaching, and other educational scenarios.
- Available in teacher and student models.
- The teacher model supports intelligent tracking, automatically capturing the teaching panorama, teacher close-ups, and whiteboard close-ups.
- The student model automatically captures classroom panoramas and student interaction close-ups.
- Built-in intelligent director algorithm automatically identifies teaching dynamics and switches to the appropriate panoramic or close-up view.
- Built-in intelligent whiteboard algorithm automatically generates a whiteboard view overlaid above the teacher to avoid occlusion.
- Supports PoE single-cable connectivity.
JX200I — 4K Dual-Lens Intelligent Tracking Teaching Camera
The JX200I is a dual-lens integrated intelligent tracking teaching camera designed for lecture capture classrooms, premium course recording, and dual-teacher classrooms.
- Integrated panoramic lens + close-up lens design.
- Supports intelligent tracking, automatically capturing the teaching panorama, teacher close-ups, and whiteboard close-ups.
- Built-in intelligent director algorithm automatically identifies teaching dynamics and switches to the appropriate panoramic or close-up view.
- Supports PoE single-cable connectivity.
VX800I2 — 4K Dual-Lens Intelligent Tracking Zoom Camera
The VX800I2 is a dual-lens tracking camera for education scenarios such as large tiered classrooms and academic lecture halls.
- 4K dual-lens integrated design.
- 107° panoramic lens, with coverage spanning the entire classroom space.
- 71° wide-angle + 12x optical zoom close-up lens, capturing clear images at both near and far positions.
- Supports intelligent tracking, automatically following the teacher’s movement to capture teaching close-ups.
- Built-in microphone array with an effective pickup distance of up to 6 m.
III. Remote Teaching Microphones: Clear Pickup for Effortless Teaching
Whether the teacher’s voice is clearly captured directly affects remote teaching effectiveness. VHD offers multiple education-specific microphones:
M702C — Teaching Array Microphone
The M702C is an array microphone for education scenarios such as standard classrooms, lecture capture classrooms, and dual-teacher classrooms.
- 6-MEMS microphone array with beamforming pickup, precisely capturing the teacher’s voice.
- Automatic noise reduction, filtering ambient noise such as students turning pages and air conditioning.
- Echo cancellation; no feedback even when used with sound reinforcement systems.
- Simple installation: ceiling-mounted or wall-mounted.
- Supports PoE daisy-chain deployment.
M710T — Cascadable Omnidirectional Array Microphone
The M710T is a ceiling-mounted microphone array designed for large classrooms, tiered classrooms, multipurpose halls, and similar scenarios.
- Suspended/ceiling-mounted design; does not occupy podium space or affect classroom aesthetics.
- Long-array design for a wider pickup range, achieving full coverage even in large classrooms.
- Beamforming technology for directional pickup, precisely capturing the teacher’s voice.
- AI noise reduction + echo cancellation; no feedback during sound reinforcement, delivering clearer audio.
- Supports cascading of multiple units for full coverage even in extra-large spaces.
IV. Non-Wearable Sound Reinforcement Solutions: Natural, Clear Audio Without a Microphone
Traditional classroom sound reinforcement has a pain point—teachers must wear a lavalier or handheld microphone, which is inconvenient and unnatural. VHD’s non-wearable sound reinforcement solution addresses this: teachers wear no microphone, speak normally, and the entire room can hear clearly.
M800 — Non-Wearable Sound Reinforcement Microphone
The M800 is VHD’s entry-level non-wearable sound reinforcement system designed for standard classrooms, small-to-medium meeting rooms, and similar scenarios.
- Teachers wear no microphone and can move freely around the classroom while teaching.
- The microphone array automatically tracks the teacher’s position for directional pickup.
- Intelligent echo cancellation + anti-feedback algorithms prevent piercing sound reinforcement.
- Simple installation and convenient commissioning for easy deployment in standard classrooms.
- Clear, natural sound indistinguishable from normal speech.
M800Pro — Professional-Grade Non-Wearable Sound Reinforcement System
The M800Pro is an upgraded and enhanced version of the M800, targeting larger spaces and higher requirements.
- Larger pickup range, achieving full coverage even in large and tiered classrooms.
- Stronger AI algorithms for more precise tracking and more thorough noise reduction.
- Supports multi-channel sound reinforcement for more even sound distribution.
- Richer interfaces and functions for connecting to more devices.
- Professional-grade audio quality with an even sound field, ensuring clear hearing at every position.
