Description The Seeed Studio Modbus RS485 Vision AI Camera combines an ESP32-C3 controller with a Himax WiseEye2 HX6538 visual AI processor for edge inference in industrial and remote monitoring projects. It runs image recognition locally at 480 x 480 resolution and 10 FPS, then sends compact inference results instead of full image streams for more efficient and privacy-aware deployments. With Modbus-RTU over RS485, optional Wi-Fi keyframe transmission, support for SenseCAP DTU workflows, IP66 protection and more than 300 SenseCraft AI models, this camera is built for object detection, people counting, meter reading, smart building and industrial manufacturing applications. Note This product includes only the AI sensor. The S2100 data logger shown in the image needs to be purchased separately. Features Local visual AI inference with the WiseEye2 HX6538 processor and integrated Arm Ethos-U55 neural processing unit. 480 x 480 model execution at more than 10 FPS for compact edge AI tasks. Edge computing workflow that sends inference results instead of continuous image streams. Three built-in model types: human detection, people counting and meter reading. Supports public and custom model deployment through SenseCraft AI. Modbus-RTU over RS485 for integration with industrial control and monitoring systems. Optional Wi-Fi keyframe transmission for inspection and setup workflows. IP66-rated enclosure for stable indoor and outdoor deployment.

Pinout Diagram Connection Schematic Resources RS485 Vision AI Camera Wiki Documentation RS485 Vision AI Camera Schematic PDF SenseCraft AI Model Deployment Platform Vision AI V2 XIAO Data Reading Guide FAQ Can the RS485 Vision AI Camera run AI models locally? Yes. It performs local edge inference with the Himax WiseEye2 HX6538 processor and can run built-in or custom models deployed through SenseCraft AI. What data does the camera send over RS485? It is designed to transmit inference results over Modbus-RTU instead of streaming full video, which helps reduce bandwidth and improve privacy. Can it send image keyframes? Yes. Wi-Fi can be used for keyframe transmission when image inspection or setup feedback is needed. Is it suitable for outdoor use? The IP66-rated enclosure supports indoor and outdoor deployment when installed correctly within the specified operating range. Which power input should be used? Use either 5V or 12V power input, but do not connect both inputs at the same time. What is included in the package? The package includes the RS485 Vision AI Camera, a 2.4GHz rod antenna, an instruction guide, a screws package and a base positioning sticker.
