Supplier's note

  1. Technical Breakthroughs:

    • Metal Chassis: Reduces thermal throttling by 30% compared to plastic enclosures, ensuring stable operation in industrial environments.
    • Auto-Negotiation: Automatically adapts to 10/100M networks, eliminating manual configuration.
    • IoT-Ready Protocol Support: Native HTTP/HTTPS client capability simplifies integration with cloud platforms.

  2. Version Selection Guide:

    • Base Model: Best for basic IoT deployments (e.g., small-scale sensor networks) where cost efficiency is critical.
    • Advanced Model: Ideal for industrial automation requiring QoS prioritization and secure data transmission (e.g., smart factories).
    • Pro Model: Tailored for extreme environments (e.g., oil rigs, outdoor surveillance) with its wide temperature range and PoE capability.

With the Pro Model’s -40°C to 85°C rating, you can deploy devices in harsh climates without performance loss. Pair this with its AES-256 encryption to ensure secure data transfer even in high-risk scenarios. For web-based control systems, the Advanced Model’s SSL encryption guarantees safe remote access.
