The Ideal Large-Screen Interactive Solution for High-Traffic Events
PoE LiDAR signature walls represent a next-generation large-format, multi-touch interactive display. By using PoE-powered LiDAR sensing, these systems overcome the limitations of traditional infrared frames and capacitive touch screens, making them ideal for high-traffic, experience-driven environments such as exhibitions, weddings, brand launches, conferences, and corporate events.
In scenarios where many users interact simultaneously, stability, accuracy, and visual impact are critical. This is where PoE LiDAR signature walls deliver clear advantages.
What Is a PoE LiDAR Signature Wall?
A PoE LiDAR signature wall is a large interactive wall or LED screen that uses LiDAR-based multi-point touch detection, powered and connected via Power over Ethernet (PoE).
Instead of relying on physical touch frames or capacitive panels, LiDAR sensors detect finger, hand, or gesture movement in space, converting them into precise touch coordinates. The result is a seamless, touch-free or near-touch interactive experience on large surfaces.

Core Multi-Touch Advantages of PoE LiDAR Signature Walls
True Multi-User, Multi-Point Interaction
PoE LiDAR systems support 200+ simultaneous touch points (commonly rated at 255 or 256 points). This allows:
- Multiple users signing at the same time
- Group graffiti or collaborative drawing
- Multi-hand gestures without point conflict or signal loss
There is no “touch stealing” or dropped points, even during peak usage.
High-Precision Tracking for Fine Visual Effects
Typical accuracy reaches less than 2–3 cm error across wall sizes of 4–6 meters. This level of precision ensures:
- Smooth handwriting that follows fingers or palms closely
- Stable particle, water flow, or star effects
- No visible drift or lag during writing
This precision is critical for signature walls with high visual expectations.
High Detection Frequency for Smooth Writing
PoE LiDAR touch systems can achieve tens of thousands of detections per second (e.g., 18,000 detections/sec). This enables:
- Continuous, fluid handwriting
- Fast graffiti and gesture effects
- No broken lines or interrupted strokes
The interaction feels natural and responsive, even with rapid movement.
Deployment and Stability Advantages of PoE Technology
One Ethernet Cable for Power and Data
With PoE, a single network cable provides:
- Power supply
- Data transmission
No additional power outlets are required at the wall or ceiling, resulting in:
- Clean hidden installations
- Faster setup and teardown
- Ideal solutions for temporary or touring events
Flexible Installation for Large Signature Walls
A single PoE LiDAR unit can cover 3 m × 4 m or larger wall areas. Multiple units can be linked to create:
- Extra-long signature walls
- Curved or irregular-shaped walls
- Large venue entrance installations
This makes PoE LiDAR especially suitable for hotel ballrooms, exhibition halls, and event lobbies.
Long-Distance Networking and Centralized Management
Ethernet connections can reach up to ~50 meters, allowing:
- Sensors installed at the wall or ceiling
- Servers placed in control rooms or backstage areas
This improves system security, simplifies maintenance, and supports centralized management.
Experience & Visual Advantages in Signature Wall Scenarios
Dynamic Particle, Water, and Light Effects
PoE LiDAR signature walls support rich visual effects such as:
- Flowing water strokes
- Spark, fire, or star particles
- Ripple, dispersion, and aggregation animations
After signing, text and graphics react dynamically, creating a strong sense of ceremony and immersion.
Touch or Touch-Free Interaction Modes
The system can operate as:
- True touch interaction (finger touches the wall)
- Near-touch gesture interaction (activation within a few centimeters)
This is especially suitable for:
- Weddings and formal events
- Brand launches
- Users wearing formal clothing or makeup
Stable Performance Under Strong Lighting
LiDAR is highly resistant to ambient light, including:
- High-brightness LED walls
- Stage lighting
- Sunlight exposure
This gives PoE LiDAR a significant advantage over infrared touch frames in bright environments.
PoE LiDAR vs Traditional Infrared & Capacitive Solutions
| Feature | PoE LiDAR | Infrared Touch Frame | Capacitive Screen |
|---|---|---|---|
| Multi-Touch Points | Very High (200+) | Limited | Limited |
| Accuracy on Large Walls | High | Medium | High (small size) |
| Strong Light Resistance | Excellent | Poor | Medium |
| Large / Curved Walls | Supported | Difficult | Not suitable |
| Installation | Hidden, PoE | Visible frame | Fixed panel |
| Event Suitability | Excellent | Limited | Poor |
For large-scale, multi-user signature walls, PoE LiDAR offers clear technical and experiential superiority.

Frequently Asked Questions (FAQ)
Q1: How many users can sign at the same time on a PoE LiDAR signature wall?
PoE LiDAR systems typically support 200+ simultaneous touch points, allowing many users to interact concurrently without interference.
Q2: Is PoE LiDAR safe for public and event use?
Yes. The LiDAR operates at low-power, eye-safe laser levels and complies with international safety standards.
Q3: Can the system work with LED screens and projections?
Yes. PoE LiDAR works reliably with high-brightness LED walls and projection systems, even under strong lighting.
Q4: Can the signature wall be customized for branding or events?
Absolutely. Visual effects, interaction logic, wall size, and software functions can all be customized via OEM/ODM services.
Q5: Is it suitable for curved or irregular walls?
Yes. Unlike infrared frames, LiDAR supports curved, extra-long, and non-standard wall shapes.
