The Firewall & IP Conflict Problem Most Interactive Installers Eventually Face One of the most frustrating situations in interactive projection projects is this: The PoE LiDAR powers on normally. The switch lights blink. The device appears connected. But: At first, many engineers suspect: But in real installation environments, another issue is extremely common: Windows silently…
Why Your PoE LiDAR Powers On — But Still Cannot Connect The “8-Core Ethernet Cable” Mistake Most Installers Miss In interactive projection projects, one of the most confusing problems is this: The PoE LiDAR powers on normally. The LEDs blink. The switch detects the device. But: At first glance, everything looks normal. But in many…
In interactive projection projects, the most frustrating issue is not calibration. It’s this: “Connection Failed.” The LiDAR appears online for a few seconds…then disconnects.Or it keeps rebooting.Or Unity / TouchDesigner cannot detect the sensor at all. At CPJROBOT, we’ve seen this issue repeatedly in: And surprisingly: Most failures are NOT caused by the LiDAR itself.…
Understanding PoE LiDAR vs. Traditional USB Sensors The transition from USB-based LiDAR sensors to Power over Ethernet (PoE) technology represents a significant shift in how we approach real-time sensing systems. While traditional USB sensors operate with straightforward point-to-point connections, PoE LiDAR systems introduce additional layers of complexity that directly impact system reliability and performance. Unlike…
Interactive projection projects often fail for a surprisingly simple reason: The LiDAR powers on.The indicator light flashes.But the software still says: “Connection Failed.” For many installers, this becomes the most frustrating part of deploying an interactive floor or wall system. They restart the software.Replace the radar.Reboot the PC.Reset the switch. But in real-world projects, most…
Introduction Interactive LiDAR systems are transforming spaces—from museums and malls to education and commercial installations. But here’s the reality: most installation failures don’t come from the hardware—they come from the environment. From our on-site experience at CPJROBOT, two issues repeatedly cause false triggers, unstable tracking, and costly rework: If you’re planning an interactive projection or…
Introduction: Why LiDAR Stability Matters in Interactive Projects In modern interactive installations—such as museums, exhibition halls, retail spaces, and immersive environments—PoE LiDAR systems play a critical role in enabling accurate, real-time touch interaction. However, real-world deployments often face issues like: These are not random failures—they are systematic and diagnosable. This guide provides a POELIDAR-F1 LiDAR…
When deploying LiDAR-based interactive systems, choosing the right touch protocol is just as important as selecting the hardware. Two of the most commonly used protocols are: From an engineering perspective, the choice between them directly affects: This guide explains how each protocol works, where it performs best, and how to choose the right one for…
Selecting the best LiDAR for interaction is one of the most critical decisions in building reliable interactive systems—especially for floor projection, interactive walls, and immersive environments. From an engineering perspective, LiDAR is not a “plug-and-play” component. Its performance depends on how well it matches: This guide focuses on practical selection criteria used in real deployments,…
Interactive floor projection systems are increasingly used in shopping malls, retail stores, and public spaces to attract attention, increase dwell time, and create memorable user experiences. From an engineering and deployment perspective, these systems are not just visual effects—they are real-time sensing + projection + interaction pipelines. The choice of sensing technology, system architecture, and…
