Integrating Traffic Video Devices for Distributed Event Detection
Smart transportation systems are moving video analytics closer to the roadside for faster local detection of traffic flow, pedestrians, and abnormal events. Designed for compact roadside installations, WEBS-91J0 offers Intel®Processor N150 or Intel Atom® x7433RE options, with support for wide-temperature deployment. Three independent 1GbE ports, RS-232/RS-485, Mini PCIe, and M.2 B-Key expansion enable flexible integration for video analytics, data connectivity, and Edge AI inference at smart intersections.
Three Independent Ethernet Ports for Traffic Segmentation
WEBS-91J0 provides three independent 1GbE ports that can be dedicated to different traffic flows, such as cameras and sensors, local edge processing, and backend management systems. Separating camera streams, field sensor data, and management traffic across physical Ethernet interfaces helps isolate network traffic and provides greater flexibility for network security zoning, system integration, and troubleshooting.
Roadside AI Inference with Flexible Field Device Integration
Camera video can be transmitted to WEBS-91J0 through 1GbE or USB 3.0 for image preprocessing. An optional Hailo-8 AI accelerator module via M.2 B-Key enables edge inference workloads such as pedestrian detection, traffic flow counting, and abnormal event detection. Detection results, event snapshots, and system status can then be sent to the management center without continuously transmitting all raw video streams, helping reduce upstream bandwidth requirements. Three USB 3.0 ports support USB cameras or external SSDs for local image acquisition and data backup. Mini PCIe can accommodate mSATA or wireless modules for local event storage and wireless connectivity. RS-232 and RS-485 interfaces also provide connectivity to existing sensors and serial devices, allowing system integrators to add edge computing capabilities while retaining deployed field equipment.
Compact Fanless Design for Roadside Cabinet Deployment
With a compact footprint of 152 × 112 × 48 mm, WEBS-91J0 supports both DIN-rail and wall mounting, making it easier to integrate into roadside control boxes and traffic equipment cabinets. Its fanless design reduces maintenance concerns associated with fan failure and dust accumulation. The Intel Atom® x7433RE configuration supports an operating temperature range of −40°C to 60°C, providing an option for roadside and semi-outdoor installations exposed to wider temperature variations. A 12–24V DC input also supports integration with commonly used industrial power systems.
From Design-In to Multi-Site Deployment
Portwell can assist with project-specific configuration of computing, storage, AI acceleration, and communication functions, along with BIOS/firmware support, compatibility validation, BOM management, and mechanical and thermal design services. These services help system integrators move from proof of concept and design-in to multi-site deployment and long-term volume production.
