Educational informatization is moving from "device stacking" toward "deep integration." Traditional premium recording classrooms often require separate audio processors, video matrices, recording hosts, control systems, switches, and multiple other devices-not only occupying significant rack space and complicating cabling, but also increasing system failure points and maintenance complexity. Addressing this challenge, TENDZONE introduces the next-generation SMART EDUCATION TERMINAL-a device that integrates eight functional modules-digital audio processing, video matrix, teaching control, media processing, video interaction, IoT control, premium recording, and PoE switching-into a 1U standard chassis using a newly upgraded high-performance processor chip, redefining the smart education terminal with an integrated architecture.
Integrated Hardware Design: Streamlined Architecture, Powerful Performance
A true TENDZONE SMART EDUCATION TERMINAL must achieve a high degree of hardware integration. The device features a soft power switch on the front panel and a hard power switch on the rear panel-a dual-switch design that ensures system safety and reliability. The rear panel features a clear layout with an exceptionally rich set of interfaces:
Video Interfaces: Multiple HDMI inputs (some supporting 4K30 resolution input) and multiple HDMI outputs, meeting the needs for accessing and presenting multiple teaching video sources
Audio Interfaces: Multiple Phoenix terminal inputs supporting 48V phantom power, with MIC input and Line input self-adaptive; multiple pairs of Phoenix terminal stereo outputs (L/R channels support independent audio output); high-power digital amplifier outputs capable of directly driving classroom speakers
Control Interfaces: Multiple RS-232/RS-485, RELAY, I/O, and IR ports, plus a debug interface, fully compatible with various environmental control devices
Network Interfaces: Multiple LAN ports supporting PoE power delivery and VLAN partitioning, enabling direct power supply to teaching tracking cameras without additional power adapters
Expansion Interfaces: USB ports supporting automatic copying of recorded content and system upgrades
This integrated design allows a single TENDZONE SMART EDUCATION TERMINAL to replace the functionality that traditionally required multiple devices, dramatically simplifying the equipment architecture and cabling complexity of premium recording classrooms.
Powerful Audio-Visual Processing Capabilities: Multi-Channel Encoding/Decoding, 4K Support
As a professional SMART EDUCATION TERMINAL, TENDZONE devices excel in audio-visual processing performance:
Encoding/Decoding Capabilities: Supports multi-channel 1080P encoding and decoding using H.265/H.264 high-efficiency encoding standards, ensuring high-definition quality while reducing bandwidth consumption
Video Input Capacity: In addition to multiple HDMI local inputs, supports access to numerous local IP network cameras with ample network forwarding capacity
Video Output: HDMI outputs support 4K30 resolution output in non-director mode, meeting the needs for ultra-high-definition teaching content presentation
Recording Functionality: Built-in high-capacity surveillance-grade hard drive supporting multi-channel simultaneous audio-video recording (dual modes: movie mode and resource mode), with support for 4K resolution composite recording
Professional Audio Processing Module: AI Algorithm Enhancement
Audio quality is one of the core experiential elements of premium recording classrooms. TENDZONE's high-performance SMART EDUCATION TERMINAL incorporates a complete audio processor module, featuring professional audio processing algorithms including AFC (Adaptive Feedback Cancellation), ANS (Active Noise Suppression), AEC (Acoustic Echo Cancellation), and AGC (Automatic Gain Control), along with pre- and post-processing modules such as expander, equalizer, compressor, delay, and limiter. The mixing function supports flexible mixing of local audio, embedded HDMI audio, and remote network audio streams, with audio routing freely configurable to LINE OUT, HDMI OUT, and amplifier AMP OUT output channels. These professional-grade audio processing capabilities ensure clear, natural sound whether for teacher instruction, student participation, or remote interaction.
Comprehensive Recording and Interaction Functions: Automatic Premium Lesson Generation
The TENDZONE SMART EDUCATION TERMINAL condenses all core functions of premium recording into a single device:
Automated Directing: Built-in web-based director console supports three directing modes-automatic, semi-automatic, and manual-enabling intelligent switching between teacher全景/close-up, student全景/close-up, blackboard content, and presentation sources. Supports independent preview and switching of PVW (Preview) and PGM (Program Output)
Schedule Integration: Supports integration with platform schedules, automatically starting and stopping recordings based on preset strategies, enabling unattended automated recording
Video Compositing: Built-in video composition functionality supports multiple layout modes including single-screen, dual-screen, triple-screen, nine-screen, and sixteen-screen, with picture-in-picture, picture-outside-picture compositing, and subtitle overlay
Remote Interaction: Supports SIP dual-stream video conferencing calls and multi-party remote teaching video interaction, with high resistance to network jitter to ensure stable interaction even during network fluctuations
Live Streaming: Supports RTMP live streaming, allowing any audio/video streams connected to the device to be selectively pushed to streaming platforms
Resource Management: Recorded files support web-based playback and download, with sorting by time and recording duration. Supports automatic copying of recorded content via USB drive (supports most recent lesson or weekly courses), facilitating teacher archiving and reuse
Intelligent Environmental Control and Centralized Management: Making Classrooms Smarter
As a TENDZONE SMART EDUCATION TERMINAL, the device not only handles audio-visual signals but also plays a central role in intelligent classroom environmental control:
Environmental Control Management: Supports configuration of control commands for RS-232/485, I/O, IR, and other control interfaces, enabling scripts, protocols, scheduled tasks, IoT gateways, audio-visual联动, device wake-up, network control, and other functions to achieve unified control of classroom lighting, curtains, air conditioning, projectors, and other devices
Distributed Visualization: Supports integration with distributed control systems, functioning as a distributed input/output interface unit for image preview, visual control, and distributed display
Remote Operations and Maintenance: Supports web-based management, providing rapid configuration of device ports, password changes, IP address modification, factory reset, software upgrades, log management, remote debugging, and other remote maintenance functions, significantly reducing on-site IT support costs
Stability and Reliability: Industrial Design, Classroom-Ready
Educational environments demand exceptional stability and durability from equipment. TENDZONE's next-generation SMART EDUCATION TERMINAL adopts an industrial-grade system architecture based on Linux development, effectively avoiding virus intrusion and system crash risks. Power consumption is finely optimized, with wide-temperature design and wide voltage input enabling adaptation to various teaching environments. Standard rack-mount design with height not exceeding 1U facilitates unified deployment and management.
Conclusion: The Core Engine of Smart Education
As the digital transformation of education advances, premium recording classrooms are moving from "demonstration-oriented construction" toward "routine application." TENDZONE's highly integrated SMART EDUCATION TERMINAL-with its 1U chassis containing all functions that traditionally required multiple devices-not only dramatically reduces system complexity but also delivers professional audio-visual processing capabilities, flexible recording and interaction functions, and intelligent environmental control management, providing schools at all levels with a stable, easy-to-use, and efficient smart teaching core engine.
When technology is no longer a burden for teachers to worry about, when every lesson can be recorded and disseminated with high quality, when remote students and local students share an equal participation experience-this is the true value that the TENDZONE SMART EDUCATION TERMINAL brings to education.
