A Display System Built Like a Control-Room Component
A surveillance video wall is not a consumer television with a bigger screen. It must hold consistent brightness across every panel, tolerate long fixed images without burn-in, and keep working while a city never sleeps. This series is engineered around those constraints so the wall behaves like one predictable part of the CCTV system, not a maintenance liability.
- Industrial A+ LCD panels with server-class high-temperature capacitors and temperature-controlled cooling.
- Built-in anti-image-retention protection for long-term fixed monitoring views.
- Whole-array calibration keeps uniform brightness and color across adjacent splicing units.
- 24/7/365 continuous operation design with stable output and no unexpected shutdown.
- Low-power architecture reduces long-term energy cost in the customer’s control room.
Ultra-narrow bezel: 0.88 mm / 1.7 mm / 1.8 mm options
What Makes This Wall Different
Four design decisions that matter on real surveillance projects: uptime, image truth, equipment reuse and controllable servicing.
24/7 Continuous Operation
Designed to run for years of shift duty, not for a season of retail display.
- Industrial A+ panel with server-level capacitors rated for high ambient temperature.
- Intelligent thermal management keeps long-run brightness stable.
- Anti-image-retention algorithm suppresses residual shadow from fixed monitoring views.
- Low power draw and ≥50,000 h backlight lifespan cut lifetime cost.
Surveillance-Grade Display Tuning
Calibrated for operators reading fast-moving scenes, not for showroom appeal.
- 500 cd/m² professional brightness keeps images readable in bright control rooms.
- ≤10 ms response time minimizes trailing on vehicles, crowds and machinery.
- High color restoration reproduces the camera’s real surveillance color and reduces misjudgment.
- Strong low-grayscale performance preserves night-time dark-area detail without black crush.
CCTV Signal Compatibility
Reuses the cameras, NVRs and DVRs you already own, so the project budget stays under control.
- Analog camera BNC input and HD coaxial SDI access.
- HDMI / VGA switching and LAN port with optional IP stream decoding (ONVIF / RTSP, H.264 / H.265).
- Compatible with mainstream NVR and DVR video output; extra sources handled by matrix, controller or decoder quoted with the screens.
- Surge and lightning protection circuitry tolerates unstable power environments in overseas projects.
Splicing Control & Industrial Hardware
Built-in management and protection that keep a large wall easy to operate and cheap to service.
Splicing & Display Modes
- Bezel options 0.88 / 1.7 / 1.8 mm for different project budgets.
- Flexible matrices: 1×2, 2×2, 3×3, 4×4 and custom layouts.
- Full screen, split screen, single screen, roaming and picture-overlay switching.
- Signal polling, patrol display and alarm window pop-up support.
Hardware & Protection
- Electromagnetic shielding resists interference from monitoring hosts and power equipment.
- Reinforced structure for long-term wall, cabinet or floor-stand installation.
- Remote network control, RS232 cascade to 30 units, one-key scene switching.
- Operating range 0–50 °C with 10–90% non-condensing humidity tolerance.
