Gateway controller Milesight SG50

The Milesight SG50 is a robust gateway controller engineered for reliable wireless connectivity in demanding environments. Housed in a metal enclosure with IP67 protection, the SG50 resists dust and water ingress, making it suitable for outdoor and industrial locations. The device operates on the 2.4 GHz band and accepts NanoSIM cards; an external antenna with gain up to 27 dBi enhances signal reception for extended range and stable links. For service and configuration, the gateway provides a USB console port and runs on a 240 MHz processor with built-in working memory and flash storage for firmware and configuration data.

Advantages

The metal casing and IP67 rating provide durable environmental protection without compromising on connectivity. The external high-gain antenna improves reception in remote or obstructed areas while the 2.4 GHz operation ensures wide compatibility with many wireless devices. Compact internal memory and flash storage support device firmware and local configuration, and the USB console port simplifies initial setup and troubleshooting. Overall, the SG50 combines rugged construction with field-oriented connectivity features.
