Comar R500NI Intelligent Network AIS Receiver with WiFi

The R500Ni with WiFi is an AIS receiver interfaced to an ARMv8 microcomputer. The R500Ni is designed for coastal monitoring applications and is capable of filtering and processing AIS data and forwarding it across a network. In this way, several R500Ni units can be used to form a complete networked monitoring solution for monitoring a port and its approaches.

The unit has both WiFi and Ethernet connectivity, as well as 4 USB ports and an HDMI connector for a monitor display. What makes the R500Ni different from other receivers is that it can be deployed in any AIS network using proprietary software specific to that network and is shipped ‘bare bones’.

The R500Ni is designed for use by the commercial market and uses Comar’s well proven and internationally specified high sensitivity dual channel parallel receiver, and is quite possibly the most flexible and powerful AIS receiver available on the market.

Note: This product was previously known as the SLR350Ni
