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 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.

networked video source.
