## Description

The Seeed Studio RS485 Vision AI Camera is an intelligent device that combines an ESP32-C3 MCU ([Seeed Studio XIAO](https://www.seeedstudio.com/Seeed-XIAO-ESP32C3-p-5431.html)) with a [Himax WiseEye2 HX6538 processor](https://www.himax.com.tw/products/wiseeye-ai-sensing/wiseeye2-ai-processor/), featuring dual-core [Arm Cortex-M55](https://developer.arm.com/processors/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](https://sensecraft.seeed.cc/ai/#/home) platform, while AI models in [TensorFlow](https://www.tensorflow.org/) and [PyTorch](https://pytorch.org/) frameworks are supported. Privacy concerns are addressed through its design to transmit only inference results, with optional Wi-Fi keyframe transmission when needed.

- **Powerful Visual AI Processing Capability**: local inference up to 480\*480 10FPS with WiseEye2 HX6538 processor featuring dual-core Arm Cortex-M55 and integrated Arm Ethos-U55 neural network unit
- **Edge Computing for High Data Security**: local image inference, send only the final result, suitable for applications requiring limited data transmission and high data privacy.
- **Multi-Functional AI Models**: shipped with 3built-in models of human detection, people count, and meter reading, and it also easy to deploy public AI models or train customizedAI models on[SenseCraft AI](https://sensecraft.seeed.cc/ai/#/home) with a few clicks.Support[TensorFlow](https://www.tensorflow.org/) and [PyTorch](https://pytorch.org/) frameworks.
- **Multi-Transmission Protocols**: Supports transmitting inference results via standard RS485 protocol; connect with [SenseCAP S2100](https://www.seeedstudio.com/SenseCAP-S2100-LoRaWAN-Data-Logger-p-5361.html)/ [4G Sensor Hub](https://www.seeedstudio.com/SenseCAP-Sensor-Hub-4G-Data-Logger-with-builtin-battery-p-4852.html) DTU to get the results via LoRaWAN or 4G. Also supports transmiting keyframes via Wi-Fi.
- **Dust and Water Resistance:** IP66-rated protection ensures stable long-term deployment in indoor and outdoor environments.
- **Model Management via SenseCraft App**: Configure and switch between pre-installed AI models with just a few taps. Easily adjust Model Confidence Thresholds to optimize performance for your specific use case.
 
 **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.
