Networked Video Devices

NOTICE

A Garmin Power over Ethernet (PoE) Isolation Coupler (P/N 

010-10580-10) must be used when connecting a PoE device, 

such as a FLIR

®

 camera, to a Garmin Marine Network. 

Connecting a PoE device directly to a Garmin Marine Network 

chartplotter damages the Garmin chartplotter and may damage 

the PoE device.

Before you can view and control video devices such as IP 

cameras, encoders, and thermal cameras using your 

chartplotter, you must have a compatible video device 

connected to your chartplotter, and you must have a marine 

network cable Power over Ethernet (PoE) isolation coupler. Go 

to 

www.garmin.com

 for a list of compatible devices or to 

purchase a PoE Isolation Coupler.
You can connect multiple supported video cameras and up to 

two video encoders to the Garmin Marine Network. You can 

select and view up to four video sources at once. Chartplotters 

with multiple composite built-in video inputs can display a single 

built-in video input only. When the cameras are connected, the 

network detects them automatically and displays them in the 

source list.
