55" 3.5mm CCTV LCD Video Wall for Control Rooms — Reduce Integration Risk with Factory-Direct Supply
Deploying a video wall isn't just about buying screens. System integrators face real challenges: signal latency, bezel misalignment, long-term stability, and maintenance costs. Qtenboard provides a complete system engineering approach — from controller selection to signal architecture and installation — to minimize integration complexity and project risk.
- ✓ 330,000 m² manufacturing — consistent panel performance across large arrays
- ✓ Front-access maintenance — reduce downtime by up to 70%
- ✓ 24/7 industrial-grade reliability — built for mission-critical surveillance
- ✓ OEM / ODM / CKD / SKD — white-label support for integrators

Solution-Oriented, Not Product-Only
Qtenboard supports LCD Video Wall projects from a system engineering perspective — treating the display as one component of a larger CCTV infrastructure.
Beyond supplying panels, we assist integrators with solution-level planning that covers:
- Control room layout — viewing distance, operator ergonomics
- Panel configuration — bezel alignment, uniform visual performance
- Controller selection — signal architecture and processing
- Installation structure — access strategy and long-term maintenance
This approach ensures the video wall operates as a stable, integrated component of the overall surveillance system — minimizing integration complexity, reducing project risk, and improving delivery efficiency.
Direct Manufacturer with Real Project Delivery Capability
330,000m² Factory · ISO-Certified · High-Capacity Manufacturing
As a direct factory, we control the full production process — from panel assembly and calibration to final quality inspection. This allows us to provide:
- Consistent panel performance across large video wall arrays
- Stable long-term supply for phased or repeat projects
- Controlled quality standards for mission-critical environments
For CCTV control rooms, where visual consistency and operational stability are essential, manufacturing control matters as much as specifications.
OEM / ODM / CKD / SKD and private-label support available for integrators and solution providers.
LCD Video Wall CCTV Projects Actually Care About
Qtenboard provides flexible customization options for different CCTV command room applications:
🎛️ Controller & System Compatibility
Built around dedicated video wall controllers, the system supports centralized signal processing and flexible screen management. When paired with media players and CMS, it enables remote content control, system monitoring, and configuration management.
⚡ Industrial-Grade 24/7 Operation
Panels are designed for continuous operation in surveillance environments where downtime, burn-in, or instability is unacceptable. 60,000-hour average lifespan.
🔧 Front Maintenance Structure
Front-access service design allows maintenance without dismantling the video wall — significantly reducing system downtime and on-site labor costs.
Centralized Management for LCD Video Wall
To accommodate different CCTV system designs, we offer three types of video wall control devices: matrix switchers (distributors), decoders, and cloud-based video wall processors.
Each option is designed for specific signal sources and system architectures — from traditional video inputs to IP-based surveillance streams. By selecting the appropriate control device, integrators can achieve efficient signal distribution, flexible screen management, and stable operation across control rooms of different scales.
☁️ Centralized Management with CMS (Optional)
When required, the system can be combined with media players and a CMS to enable centralized and remote management. The CMS serves as a management layer for configuration, system monitoring, and controlled content distribution — enhancing operational efficiency while maintaining reliability and security.

Which Video Wall Configuration Fits Your Control Room?
Different surveillance environments have different requirements. Here's our recommended approach based on project type.
🚔 Police & Emergency Command Centers
- Screen Size: 55" — 65"
- Bezel: 3.5mm (near-seamless)
- Brightness: 500 cd/m²
- Controller: Decoder + Matrix
- Key Feature: 24/7 reliability + low latency
→ Real-time incident monitoring requires instant signal switching and zero visual distraction
✈️ Airports & Transportation Hubs
- Screen Size: 49" — 55"
- Bezel: 1.8mm — 3.5mm
- Brightness: 700 nits (high ambient light)
- Controller: Cloud-based processor
- Key Feature: Multi-source signal + remote management
→ High ambient light environments require higher brightness and remote monitoring capability
🏢 Corporate Security & Enterprise NOCs
- Screen Size: 43" — 55"
- Bezel: 3.5mm (cost-effective)
- Brightness: 500 cd/m²
- Controller: Matrix switcher
- Key Feature: Cost-efficiency + ease of maintenance
→ Balance between performance and budget with front-access maintenance
