The Seeed Studio RS485 Vision AI Camera is an intelligent device that combines an ESP32-C3 MCU (Seeed Studio XIAO) with a Himax WiseEye2 HX6538 processor, featuring dual-core Arm Cortex-M55 and an integrated Ethos-U55 neural processor. This advanced camera delivers high-performance AI recognition at 480×480 resolution and 10 FPS, while maintaining low power consumption through flexible options for transmitting inference results. With its standard Modbus RS485 interface, it seamlessly integrates with industrial systems and supports both LoRaWAN and 4G connectivity through SenseCAP DTUs or other standard RS485 DTU devices. Protected by an IP66-rated enclosure, it withstands harsh environmental conditions, making it ideal for both indoor and outdoor applications. The camera excels in various computer vision tasks including headcount, object detection, and classification. Users can deploy models from over 300 pre-trained models or train custom models on the no-code SenseCraft AI platform, while AI models in TensorFlow and PyTorch frameworks are supported. Privacy concerns are addressed through its design to transmit only inference results, with optional Wi-Fi keyframe transmission when needed.

What is Modbus RS-485?

Modbus RS-485 is an efficient and reliable serial communication standard, suitable for various applications that require long-distance and multipoint connectivity. Its noise immunity and flexibility have made it widely used in industrial and communication sectors.

How does Modbus RS-485 work?

Modbus RS-485 uses a pair of signal lines (A and B) to transmit data, providing excellent noise immunity and supporting half-duplex communication modes. It allows for the connection of up to 32 devices on the same bus, with each device having a unique address for identification in sending and receiving data. This standard is widely used in industrial automation, remote monitoring, and other applications, and when combined with the Modbus protocol, it facilitates efficient data exchange and management between devices.
