A provincial government-run vocational training institute in Mozambique delivers technical training for local youth and in-service teachers, covering electrical engineering, auto repair, agriculture and forestry practical courses. The campus consists of multiple training buildings with year-round daily sessions.

Restricted by local infrastructure, most classrooms lack full-day air conditioning, creating an environment with high temperatures and heavy dust throughout hot seasons. Daily teaching sessions last 10–12 hours, running six days a week.

The campus previously relied on traditional projectors paired with basic whiteboards. Only two full-time IT staff manage equipment across dozens of classrooms, spending excessive time traveling between buildings for routine inspections and emergency repairs.

1. Projector lamps suffered accelerated wear under harsh local conditions, requiring bulk replacement every 3 months and generating recurring administrative and procurement costs.

2. High heat and dust severely degraded projection brightness. Afternoon sunlight glare made on-screen teaching materials unreadable for trainees, disrupting hands-on practical training.

3. No remote device monitoring platform was available. Malfunctions such as black screens, system freezes and abnormal standby power consumption could only be diagnosed by on-site IT visits, with zero advance fault alerts.

4. Conventional whiteboards only supported physical handwriting without digital saving or content sync. Step-by-step training notes could not be shared digitally for after-class review or remote supplementary learning.

1. Hardware built to withstand harsh local conditions: fully sealed dust-proof touch layers, reinforced metal chassis with high-temperature tolerance, supporting 12+ hours of continuous daily operation.

2. All-in-one integrated teaching functionality including digital annotation, file storage and wireless casting, to fully replace the separate projector-whiteboard setup.

3. Centralized DMS remote management system for unified real-time monitoring of device online status, internal temperature and fault alerts across all campus units, plus remote firmware updates and teaching material distribution.

4. Commercial long-term warranty tailored to high-temperature, dusty operating environments to cut long-term after-sales replacement expenses.

1. Hardware: Fully sealed dust-proof infrared touch screens with reinforced cold-rolled metal frames and dedicated active cooling ducts, perfectly suited for unairconditioned hot classrooms. Multi-point writing and palm rejection support simultaneous annotation by multiple trainees during practical workshops.

2. Management: All panels connected to the campus exclusive cloud DMS backend. IT administrators monitor equipment runtime, internal temperature and online status from a single office, remotely push training courseware and lock unauthorized third-party applications uniformly.

3. Deployment Phasing: Full campus replacement rolled out in 3 phases during holiday and weekend breaks to avoid disruption to scheduled training sessions. Spare units were pre-stored in each building for instant emergency swap-outs.

32 total training classrooms across the full campus completed in 3 holiday phases. Equipment was manufactured and shipped to local ports 45 days in advance for customs clearance and delivery, paired with hands-on DMS operation training for the campus IT team.

A leading private education group operates four campuses across Hanoi and Ho Chi Minh City, offering undergraduate and vocational degree programs. The university rolled out hybrid teaching as a core academic standard: large lecture halls accommodate hundreds of in-person students while live streaming sessions for remote part-time learners and international exchange students joining virtually.

Prior to the upgrade, classrooms were fitted with a disjointed mix of consumer smart TVs and outdated projectors with no unified management system, leading to persistent instability during remote lectures and consistent complaints from teaching staff.

1. Consumer-grade TVs and projectors failed to sustain stable 2–3 hour Zoom Rooms sessions, frequently suffering frame freezes, microphone disconnections and casting dropouts that caused remote students to miss critical lecture content.

2. No native on-screen annotation tools were available. Instructors were forced to annotate slides on personal laptops rather than the main display, with live handwriting invisible to remote attendees.

3. Dispersed equipment lacked centralized oversight. IT teams across four campuses could not uniformly check device power status, firmware versions or fault logs, requiring manual on-site visits for every system update.

4. Specialized coursework relied on Windows-only professional teaching software, which consumer Android TVs could not support, forcing messy extra laptop wiring in every lecture room.

1. Zoom Rooms certified commercial interactive panels engineered for stable multi-hour virtual sessions with seamless integration of campus PTZ cameras and microphone arrays.

2. Dual-system architecture: lightweight native Android OS for instant digital annotation, paired with swappable OPS Windows modules to run discipline-specific academic software.

3. Cross-campus DMS centralized management to enable unified backend oversight for all Hanoi and Ho Chi Minh City devices, supporting remote firmware deployment and real-time hardware diagnostics.

4. Extended commercial warranty engineered for daily 8–10 hour heavy university use to reduce bulk after-sales costs across multiple campuses.

1. Dual-System Compatibility: Hot-swappable OPS Windows modules run specialized design, statistics and engineering teaching software. The embedded Android layer delivers real-time multi-color annotation, shape drawing and slide saving synced live to Zoom remote participants.

2. Conferencing Optimization: Fully Zoom Rooms certified hardware with robust enterprise wireless casting, natively paired with existing lecture hall camera and microphone hardware for synchronized audio-video and live digital whiteboard sharing.

3. Cross-Campus Centralized Control: All devices onboarded to the group’s unified cloud DMS platform, shared by IT staff in both Hanoi and Ho Chi Minh City. Teams remotely batch-update firmware, restrict non-educational applications and export full equipment performance reports without cross-city travel.

4. Staged Installation: Construction scheduled exclusively between academic semesters, with 10–15 lecture halls upgraded per phase to avoid disrupting active teaching terms.

68 large lecture halls across four Hanoi and Ho Chi Minh City campuses, completed in four holiday installation phases. Equipment shipped in staggered batches to local Vietnamese warehouses, paired with full DMS platform training for AV teams at both city campuses.
