The R450 series is a professional-grade AIS receiver range, designed for shoreside monitoring of vessel traffic within VHF range. It decodes all AIS message types, including Class A, Class B, Aids to Navigation, and SARTs, delivering comprehensive situational awareness for ports, authorities, and commercial users.

With both Ethernet and built-in WiFi connectivity, the R450 streams AIS data directly to PCs, servers, or mobile devices over wired or wireless networks. It supports local monitoring, sharing data across a network, or sending AIS data over the Internet to a fixed IP address for centralised display.

The R450 series is offered in a number of variants to suit different requirements:

X Series use a Lantronix® XPort® module, supporting up to 4 TCP and 1 UDP client/server connections.

E Suffix models are Ethernet-only variants and do not include a Wi-Fi module. (Contact us for more information)

G Suffix models include an integrated GNSS receiver.
