GC™ 255 flush-mount camera, stainless steel

To install the GC™ 255 camera, you will need the following tools:

A 55 mm (2 3/16 in) hole saw for hulls less than 12 mm (1/2 in) thick, or a 57 mm (2 1/4 in) hole saw for hulls 12 mm (1/2 in) thick or thicker. 3.2 mm (1/8 in) and 4.5 mm (3/16 in) drill bits suitable for the mounting surface material. An 8 mm (5/16 in) torque wrench for SMA connectors, capable of tightening to 9 kgf-cm (8 lbf-in.). An 8 mm (5/16 in) wrench to hold the SMA connector. A TORX T10 screwdriver or bit. A #2 Phillips screwdriver. A torque screwdriver capable of tightening to 11.5 kgf-cm (10 lbf-in.). 3M™ 5200 marine adhesive sealant or equivalent. (Optional) Fiberglass or epoxy to seal the inside of the camera hole on a sandwich or composite hull.

For optimal performance, the GC™ 255 camera must be mounted above the waterline. The GVAM 10 black housing should be installed in a location that will not be submerged, with adequate ventilation to prevent heat buildup. It is also important to mount the black housing and route its integrated network cable at least 71 cm (28 in) away from noisy electrical sources, such as ignition wires and other sensitive electronic devices. Ensure you have sufficient space for routing and connecting all cables.

The GC™ 255 camera uses Garmin BlueNet™ network technology and is compatible with Garmin BlueNet devices as well as Garmin Marine Network devices. For connection:

If your boat is equipped with a Garmin BlueNet chartplotter, connect the black GVAM 10 box's integrated Garmin BlueNet cable to an available network port on your Garmin BlueNet chartplotter or on a Garmin BlueNet 20 switch. If your boat is equipped only with Garmin Marine Network devices, you will need to use a Garmin Marine Network adapter cable (reference 010-12531-01, if not provided) to connect the black GVAM 10 box to your network.A GPSMAP chartplotter compatible with Garmin Marine Network is required to view the camera's video feed.

Yes, the Garmin GC™ 255 camera is specifically designed for demanding marine environments. Its stainless steel construction provides robustness and corrosion resistance, ensuring a reliable and durable monitoring solution for your vessel. It is a fixed and discreet solution, ideal for monitoring key areas such as the anchor locker, engine compartment, or stern.

Yes, the GC™ 255 camera features an adjustable lens module that can tilt down by up to 35 degrees within its housing. This allows you to optimize the field of view for specific applications, ensuring a clear view of objects close to your vessel. Additionally, the camera can be mounted upside down, for example on the bow, and the image can be rotated in software on your chartplotter to achieve the desired orientation.

Yes, it is possible to extend certain cables, but with specific precautions:

Coaxial cable: An 8 m (26.25 ft) coaxial cable is included. If you need a longer length, you can purchase a 25 m (82 ft) Garmin coaxial cable (reference 010-13026-02). It is important not to cut or splice the supplied coaxial cable, as failures caused by a modified cable are not covered by the warranty.BlueNet™ cable: A 2 m (6.56 ft) cable is built into the GVAM 10 black housing. It can be extended by purchasing an additional Garmin BlueNet cable and a Garmin BlueNet coupler from your Garmin dealer.Power cable: A 2 m (6.56 ft) power cable is built into the GVAM 10 black housing. It can be extended using a wire of the appropriate gauge for the extension length (e.g., 20 AWG for up to 18 m, 18 AWG for up to 29 m, 16 AWG for up to 47 m). Use only wire with 105° C or higher insulation.

Drilling requirements vary depending on the thickness and type of your hull:

For a hull with a thickness of less than 12 mm (1/2 in), use a 55 mm (2 3/16 in) hole saw.For a hull with a thickness of 12 mm (1/2 in) or greater, use a 57 mm (2 1/4 in) hole saw.If your vessel has a sandwich or composite hull, you must use a slightly larger hole saw and seal the inside of the drilled hole with fiberglass, epoxy, or another material suitable for the hull type to prevent moisture from entering the hull core.The mounting hole must be drilled perpendicular to the hull surface.

The Garmin GC™ 255 camera stands out with its flush-mounted design and rugged stainless steel construction, specifically engineered for demanding marine environments. Unlike add-on cameras or PTZ units, it provides a fixed and durable surveillance solution, featuring an adjustable lens module allowing up to 35 degrees of tilt to optimize the field of view.

The GC™ 255 camera must be mounted above the waterline. We recommend installing it with the lens pointing downward at approximately 35 degrees relative to the waterline to ensure an adequate view of objects close to your vessel.

It can also be installed upside down (for example, on the bow) and the image can be rotated in the chartplotter software to achieve the desired field of view.

To install the Garmin GC™ 255 camera, the following tools are required:

A 55 mm (2 3/16 in) hole saw for hulls less than 12 mm (1/2 in) thick. A 57 mm (2 1/4 in) hole saw for hulls 12 mm (1/2 in) thick or more. A 3.2 mm (1/8 in) drill bit suitable for the camera’s mounting surface. A 4.5 mm (3/16 in) drill bit suitable for the black housing’s mounting surface. An SMA 8 mm (5/16 in) torque wrench capable of 9 kgf-cm (8 lbf-in.). An 8 mm (5/16 in) wrench. A TORX T10 screwdriver or bit. A #2 Philips screwdriver. A torque screwdriver capable of 11.5 kgf-cm (10 lbf-in.). 3M™ 5200 marine adhesive sealant or equivalent. (Optional) Fiberglass cloth or epoxy to seal the inside of the camera hole on a cored or composite hull.

To prepare the mounting hole for the GC™ 255 camera:

Use a 55 mm (2 3/16 in) hole saw if the hull is thinner than 12 mm (1/2 in). Use a 57 mm (2 1/4 in) hole saw if the hull is 12 mm (1/2 in) or thicker. Drill the mounting hole perpendicular to the hull surface. If the vessel has a cored or composite hull, use a slightly larger hole saw and seal the inside of the drilled hole with fiberglass, epoxy, or another suitable material for the hull type to prevent moisture from entering the core.

Yes, the GC™ 255 camera can be mounted upside down, for example on the bow. In this case, tilt the lens upward to achieve the desired field of view and rotate the image in software on your compatible Garmin chartplotter.

The GC™ 255 camera uses Garmin BlueNet™ network technology and is compatible with Garmin BlueNet devices as well as Garmin Marine Network devices. To connect to a Garmin Marine Network, a Garmin Marine Network adapter cable may be required (part number 010-12531-01).

To display images from the GC™ 255 camera, you need a compatible GPSMAP® chartplotter. The video signal is routed via the included GVAM 10 black box, which connects to your chartplotter's network.

It is strongly advised against cutting or splicing the coaxial cable supplied with the GC™ 255 camera. Failures caused by a modified coaxial cable are not covered by the warranty. If you require a longer length, a 25 m (82 ft) coaxial cable is available for purchase (reference 010-13026-02).

The adjustable lens module inside the GC™ 255 camera can tilt downward within its housing by up to 35 degrees. This flexibility allows optimizing the field of view for specific applications, such as monitoring objects close to the vessel.

When mounting the GVAM 10 black housing, consider the following:

The housing must be mounted in a location where it will not be submerged. It must be installed in a well-ventilated area to prevent heat buildup. Mount the housing and route its integrated network cable at least 71 cm (28 in) away from noisy electrical sources, such as ignition wires and other sensitive electronic devices. Ensure the location allows for routing and connection of all cables.

The camera comes with mounting screws, but they may not be suitable for your hull material. It is essential to use screws appropriate for your hull material to avoid damage. Always check compatibility before installation.

The GC™ 255 camera system includes the following cables:

An 8 m (26.25 ft) coaxial cable to connect the camera to the black housing.A 2 m (6.56 ft) Garmin BlueNet™ cable integrated into the GVAM 10 black housing.A 2 m (6.56 ft) power cable integrated into the GVAM 10 black housing.

To ensure the mounting template is printed at the correct scale (100%), follow these instructions:

When printing the template, make sure the scaling option is set to "Actual size" or "100%" in your PDF print settings. After printing, use a ruler to measure at least one dimension line on the template to verify it has been printed at 100% scale. It is recommended to use the template provided in the product box for the highest accuracy.
