Field-proven deployments.

Six representative installations — K-12, vocational, higher education and mobile training. Each follows the same pattern: what the scenario was, who it was for, which hardware was deployed, and what it changed in the room.

Smart classroom with 4K interactive flat panel and embedded 1U recording host Wall-mounted director display showing live recording feeds in a classroom
CASE 01

Smart Classroom & Interactive Lecture Capture

Scenario
K-12 & higher education smart classroom upgrade
Audience
School districts & educational system integrators
Deployed
4K interactive flat panel with smart blackboard system; 1U embedded 4K recording host; multi-camera AI tracking & audio capture; wall-mounted auxiliary director display

The host sits in the classroom control hub and captures slides, teacher close-ups and the full-classroom view simultaneously through 4x HDMI inputs with multi-channel H.265 encoding. A wall-mounted director screen runs automated 8-layout switching, so the instructor can see exactly what is being recorded without an operator.

CASE 02

Smart Classroom & Auto-Tracking Recording

Scenario
Turnkey AV classroom combining interactive display, physical blackboard writing and automated lecture recording
Deployed
Interactive flat panel with sliding blackboard system; 1U embedded 4K multi-channel recording host; dual-lens PTZ tracking camera (teacher & student); Windows / Android dual OS with one-key switching

All-in-one integration means 4K display, chalk and marker writing, and multi-angle capture share one installation. The embedded Linux recording architecture was chosen for 24/7 low-maintenance operation — no PC to reboot, no software to update before a lesson.

Mobile recording cart with overhead macro camera and preview screens Macro camera arm positioned over a work surface for detailed demonstration
CASE 03

Mobile Practical Training & Macro Recording

Scenario
Medical training, biological experiments and high-precision technical demonstrations
Deployed
All-in-one mobile cart base with integrated storage and power; HD overhead macro camera on a flexible mechanical arm; twin auxiliary preview screens; large interactive flat panel on mobile stand; 1U embedded 4K recording host

High-magnification optical zoom captures fine work — circuit board soldering, dissection, surgical procedure — and streams it in real time to both the local big screen and remote platforms at low latency. Because the whole system is cart-based, one unit moves between labs, operating rooms and lecture halls.

Vocational college classroom with large interactive panel and recording system
CASE 04

Vocational Education Smart Classroom

Audience
Vocational colleges and career development training centres
Deployed
Large-format interactive flat panel with push-pull blackboard; 1U industrial-grade 4K multi-channel recording host; wide-angle ceiling microphones and auto-tracking PTZ cameras; wall-mounted central control panel for one-key power and source switching

Built for instructors who teach in a workshop rhythm: one key powers the room and selects the source, so a lesson starts without a setup routine. Recording runs in the background with high reliability, because the same room doubles as a training-centre classroom.

Standard K-12 classroom cabinet housing the 1U recording host and amplifiers
CASE 05

Standard K-12 Classroom & Recording System

Scenario
Standardised lecture capture for primary and secondary schools
Deployed
Interactive flat panel with wall-mounted sliding blackboard; standard floor-standing AV server cabinet housing the 1U recording host and amplifiers; ceiling-suspended auxiliary director display; ceiling-mounted microphones and multi-angle tracking cameras

Centralised cabinet management keeps the electronics out of the teaching area — the cabinet holds the recording host and amplifiers, while the director display hangs from the ceiling for unobstructed sightlines. This is the configuration we ship most often for municipal rollouts.

Classroom with 4K interactive flat panel, sliding blackboard and document camera
CASE 06

Smart Blackboard & Document Camera Classroom

Scenario
Standard interactive classroom upgrade without a recording host
Deployed
Large-format 4K interactive flat panel; wall-mounted push-pull sliding blackboard (chalk and marker compatible); high-resolution desktop document camera (visualiser)

The entry-level configuration for schools that need display and live visualisation first. Real-time paper and specimen projection sits beside traditional chalk writing, and the panel keeps the same interface as the recording-equipped rooms for later expansion.

Tender support

What integrators get with the hardware.

Every project above was delivered with the same package of paperwork and commercial support.

Documents

Bid-ready paperwork

Authorization letters, specification deviation tables, and CE / FCC / RoHS compliance documents for the model quoted.

Testing

Sample units first

One or two sample units can be ordered for engineering testing and integration, with remote technical support during local trials.

Commercial

Tier pricing

Tiered pricing for project quantities, so partners can price a tender competitively and still hold margin.

Need references for a tender?

Tell us the country, sector and scope. We will send matched project references and the hardware list behind them.
