55" 3.5mm CCTV LCD Video Wall for Security Control Rooms
Qtenboard manufactures CCTV LCD video walls direct from the factory for 24/7 security monitoring. The 55" 3.5mm ultra-narrow bezel model is our best-selling configuration for police command centers, transportation control rooms and enterprise NOCs — near-seamless imaging, industrial-grade reliability, and low integration risk for the system integrators who spec it.
- 3.5mm ultra-narrow bezel for near-seamless multi-screen arrays
- 500 cd/m² brightness, 700 cd/m² optional for high ambient light
- 24/7 industrial-grade operation, ~60,000 hour panel service life
- Front-access maintenance cuts service downtime by up to 70%
- OEM, ODM, CKD and SKD private label support for integrators
Why System Integrators Choose Qtenboard
A CCTV video wall lives or dies on details buyers rarely see in a spec sheet — signal latency, bezel alignment, long-term panel stability, and how expensive it is to service five years in. Qtenboard takes a systems-engineering approach across controller selection, signal architecture and installation, so the wall stays a dependable part of your surveillance network, not a recurring line item.
Integrated manufacturing space, for consistent panel performance across large arrays.
Rated panel service life — roughly 7 years of continuous 24/7 operation.
Ultra-narrow bezel, for a near-seamless viewing surface across the wall.
Countries with deployed projects, from national police rooms to airports.
Key Features Built for CCTV Control Rooms
3.5mm Ultra-Narrow Bezel
The 3.5mm splicing gap keeps the image nearly seamless across the wall, so operators read camera feeds instead of tracking bezel lines. Tighter seams — down to 1.8mm, 0.88mm, or a fully seamless 0mm — are available for projects that need them.
- Near-seamless visual experience for multi-screen arrays
- Uniform brightness and color across every panel
- Factory-calibrated alignment for fast on-site installation
24/7 Industrial-Grade Reliability
Control rooms don't get scheduled downtime. Every panel is built for continuous operation in mission-critical settings, rated for roughly 60,000 hours of service with industrial components sized for round-the-clock duty.
- Built for zero downtime in 24/7 monitoring environments
- Stable long-term brightness and color consistency
- Protection against burn-in and signal instability
Front-Access Maintenance Design
Servicing shouldn't mean dismantling the wall. Technicians reach panels, power supplies and signal boards directly from the front, which cuts both downtime and on-site labor cost.
- Cuts service downtime by up to 70%
- Lower on-site labor cost over the life of the project
- Works with cabinet, wall-mounted and hydraulic stand structures
Centralized Signal Processing and CMS Remote Management
Dedicated video wall controllers handle centralized signal processing, flexible screen layouts and multi-source input. Add media players and a CMS, and the whole network gets remote content control, monitoring and configuration from one place.
- Centralized control of signal routing and screen layout
- Remote content distribution and system monitoring via CMS
- Compatible with external matrix switchers and third-party control

Multiple Sizes and Bezel Options
Match the panel size to your room scale and the bezel to your viewing standard — all at factory-direct pricing, with consistent panel quality across every unit in the array. Mixed-size arrays and custom dimensions are available for non-standard room layouts.
Available Panel Sizes
Bezel Width Options
Wider bezels are the most cost-effective choice for budget-sensitive projects; 0.88mm and 0mm configurations give premium command centers a virtually seamless canvas.
Choose the Right Configuration
Every size and bezel combination ships with the same industrial-grade backlight, 178° viewing angle and calibration process. The 55" 3.5mm model remains the most balanced choice for CCTV walls: large enough for multi-camera layouts, narrow enough for near-seamless monitoring, and cost-efficient for phased rollouts.
- Consistent panel performance across mixed-size arrays
- Custom bezel, brightness and panel color available
- Same controller and CMS ecosystem across all sizes

Real-World Deployments
Qtenboard video walls run around the clock in police command centers, airport operations rooms and enterprise security networks across more than 100 countries. Three representative projects below.
National Police Command Center
A Brazilian national police force consolidated feeds from 2,000+ cameras across 12 cities into one command center, using a 3×3 array of 55" 3.5mm panels with dedicated decoders and a cloud-based CMS.
- 40% reduction in signal switching latency
- Zero unscheduled downtime in the first 12 months
- 70% faster maintenance with front-access design
- 24/7 remote monitoring supported by Qtenboard engineering
Airport Operations Control Center
An airport in the UAE deployed a 2×4 high-brightness video wall for security, baggage and flight operations. Cloud-based processors handle multi-source signal input with remote management across terminal zones.
- 700 cd/m² panels for bright terminal environments
- Multi-source signal from security, baggage and flight systems
- Remote monitoring and configuration across zones
- Near-seamless 3.5mm bezel for uninterrupted situational awareness
Corporate Security NOC
A corporate network operations center in Vietnam built a cost-efficient monitoring wall with 55" 3.5mm panels and a matrix switcher, covering building access, parking and perimeter cameras with simple maintenance.
- Cost-efficient configuration for enterprise budgets
- Front-access maintenance without dismantling the wall
- Flexible split-screen and full-screen camera layouts
- Expandable to decoder-based IP architecture
Factory-Direct Manufacturing and Quality Control
With 330,000m² of integrated manufacturing space, Qtenboard controls the full production process — panel assembly, calibration, final inspection — in-house. That means consistent panel performance across large arrays, stable supply for phased projects, and quality control built for mission-critical environments.
- Cleanroom assembly with automated production lines
- Per-panel calibration of brightness and color consistency
- 100% aging test before shipment for 24/7 reliability
- Stable supply for phased and repeat projects
Every panel runs a full aging test before it leaves the factory, simulating continuous operation to verify stability, burn-in resistance and signal reliability under load. For control rooms where visual consistency and uptime matter as much as the spec sheet, manufacturing control is the difference.
- Full aging test program on every production batch
- Signal and interface verification before packaging
- Custom wood case packaging for safe international shipping
