Video walkthrough

▶ Adding a Garmin GC200 Camera (3:26)

Overview

BRNKL supports video feeds from the Garmin GC 200. The older Garmin GC 14 is supported through a video encoder — see the GC 14 section below.

The following Garmin camera models are not currently supported by BRNKL:

  • Garmin GC 245

  • Garmin GC 255

Install GC 200 camera

  1. Mount the camera according to the manufacturer's instructions.

  2. Connect the camera to the vessel's Garmin network.

  3. If the camera is connected through a Garmin GMS 10 network switch and you want the camera available 24/7, follow Connect GMS 10 switch to ground terminal to configure the switch for always-on operation, and ensure the switch is powered by a 24/7 source.

Prepare GC 200 camera

Find camera IP address

If BRNKL is connected via USB Ethernet adapter

  1. Open BRNKL Device Manager > Settings > Cameras.

  2. Click + Add Camera.

  3. From Available Cameras, find the camera and make note of its IP address.

If BRNKL is connected via VLAN in a router

  • Check the router's device list for the camera's IP address, or

  • Connect a laptop or smartphone directly to the camera's network and run an IP scanning tool such as LAN Scanner or Advanced IP Scanner.

Log in to the camera

  1. Open a browser and navigate to the camera's IP address.

  2. Log in using the credentials below.

Default GC 200 login:

  • ID: admin

  • Password: 1234

Configure stream settings

  1. In the camera's web interface, go to Setup > Camera > Stream Format.

  2. Under 1st Stream Setting, configure the recommended values (see Add camera for the full list — at minimum, set Frame Rate: 20 fps and Bitrate: 2400000 bps).

  3. Click Save.

Assign a static IP address

  1. In the camera's web interface, go to Network > Network Setting.

  2. Set IP Type to Static.

  3. Configure as follows:

    • If BRNKL is connected to the Garmin network via USB dongle:

      • IP Address: the camera's current IP address

      • Subnet Mask: 255.255.0.0

      • Default Gateway: 172.16.6.0

    • If BRNKL is connected to the Garmin network via VLAN:

      • IP Address: 172.16.6.__ — pick a unique number between 50–90 and record the full address

      • Subnet Mask: 255.255.0.0

      • Default Gateway: 172.16.6.200

  4. Click Save.

Add GC 200 to BRNKL Device Manager

The credentials used to login to the camera webpage are different than those used to add it to BRNKL.

  1. Open BRNKL Device Manager > Settings > Cameras.

  2. Click + Add Camera. If BRNKL is connected to the Garmin network via USB Ethernet adapter, the camera will be auto-discovered. Otherwise, click + Enter camera IP address and enter the IP manually.

  3. Enter credentials:

    • Username: root

    • Password: (leave blank)

  4. Enter a descriptive name (e.g., Engine Room, Cockpit) and click Add.

Some older GC 200 units use Username: root and Password: 1234. Try these if the blank password doesn't authenticate.

GC 14 via Axis P7304 encoder

The Garmin GC 14 outputs analog composite video and can't connect to BRNKL directly. To use a GC 14, run its video signal through an Axis P7304 video encoder, which converts the feed to a network stream that BRNKL can read.

Wiring

  1. Connect the GC 14's BNC video output to one of the encoder's BNC inputs (BNC 1–4).

  2. Connect the encoder to the vessel's Garmin network with an Ethernet cable.

  3. Power the encoder (12 V DC or Power over Ethernet, depending on installation).

Configure the encoder

Follow the standard Axis setup workflow on Add Axis cameras and encoders. The encoder appears to BRNKL as an Axis device, and each BNC input maps to a separate camera view.

Enable anonymous viewing on the encoder

For the encoder's video stream to appear on the Garmin MFD, anonymous viewing must be enabled on the Axis P7304. Without this, the MFD will not be able to access the stream.

  1. Log in to the encoder's web interface.

  2. Go to Settings > System > Users (or Settings > System > Plain config > Network, depending on firmware).

  3. Enable Anonymous viewer login (or Allow anonymous viewers).

  4. Save the settings.

The encoder's video streams should now be visible to the Garmin MFD as well as to BRNKL.

Add the encoder to BRNKL Device Manager

To add the encoder feed to BRNKL, follow Add Axis cameras and encoders. To view a specific encoder input, use the RTSP URL format and adjust the camera= parameter:

rtsp://<username>:<password>@<ip>/axis-media/media.amp?camera=1

Set camera=1 through camera=4 to match the BNC input the GC 14 is connected to.
