Installation Planning
You should consider a number of factors in planning the installation of the MV/
MU-Series camera and JCU.
General Location Considerations
First determine a good location for mounting the MV/MU-Series system body and the JCU. The system has four pigtail cable connections:
• One for power; approximately 45 cm (18 in)
• One for Ethernet connection for the JCU and/or digital video; approximately 122 cm (48 in)
• Two for the analog video; approximately 152 cm (60 in)
More than one JCU can be installed to control the camera and more than one display can be used to view the video. Also, a single JCU can be used to control more than one camera. Most often, the JCU and video monitor are mounted close together, as a pair, so the video can be viewed when the camera position (pan, tilt, zoom) is changed with the JCU.
When determining the component locations, consider how the system may be expanded in the future. For example, you may want to add an additional monitor, or perhaps a JCU and monitor pair.
Camera Location Considerations
Consider the following points when determining the camera location:
• Mount the IP66-rated MV/MU-Series camera body as high as practical, but without interfering with any radar, navigational, or communications electronics. and minimizing the degree to which vessel structures block the camera’s 360° view. The camera’s continuous-pan design lets it rotate and point in all directions. It is a good practice to test the unit at the planned installation location with typical vessel electronics active prior to mounting the camera.
• Mount the camera as close to the vessel’s center line as possible so you will have a symmetrical view of on-coming traffic, obstacles, and other navigational hazards.
• An appropriate camera mount suited for the camera mass and potential vibration and mechanical shock is important for proper camera functioning. The camera is tested to hold position for mechanical shock up to 9g transverse and
15g vertical. Improper mounts that are loose and/or resonate can magnify vessel impacts causing the camera to be unable to maintain pointing direction.
• A final location consideration is the camera’s relation to other navigation devices. If you are relying on a magnetic compass for navigation and direction, you should establish a “compass safe distance” for any object placed in its vicinity, especially any electronic equipment. The magnetic compass safe distance for the camera is 20 cm (7.9 in).

MV/MU-Series Camera Body Handle
Caution:
The MV/MU-Series camera weights 27 kg (60 lb). Handling should be done in a secure manner to avoid potential shocks that could damage the product.
To move the MV/MU-Series camera to its location on board the vessel, you may want to use the hook lifting screw on top of the camera head. To access it, pry off the cover at the top of the camera body with a soft screwdriver. Screw the lifting hook into the threaded hole.

Camera Mounting Options
Your MV/MU-Series camera can be installed in an upright or upside down position.
Make sure you have ordered the proper version before installation.
Upright Installation
In most installations, the MV/MU-Series is mounted upright on top of a mounting surface, with the pan/tilt base below the camera; this is known as the ball up orientation. Optionally, the unit can be hung upside down or ball down.
Once the mounting location has been selected, verify that both sides of the mounting surface are accessible. The camera mounting surface must be at least as large as the footprint of the camera itself to ensure an adequate seal with the Oring.
The installer must provide mounting hardware which results in a maximum insertion depth into the camera base not to exceed 25 mm.
Caution:
Do not remove the screws in the base of the camera or disassemble the camera unit. The camera unit is sealed at the factory. Disassembling the camera will compromise the seals and will void the warranty.
Caution:
Use all the 10 mounting holes to secure the camera rigidly.
Camera Video Options
The video from MV/MU-Series models is provided as composite or analog video over two coaxial cables and as digital video over Ethernet (when connected to a local area network (LAN). The multiple payloads of the system provide between three and four video feeds (based on model) which must then be selected and configured for both the composite and digital outputs. Any two video feeds are available at any one time.

Joystick Control Unit - Back
Joystick Control Unit (JCU)
Mount the JCU in a convenient area that is close to the monitor being used to display the MV/MU-Series video output. Make sure the area you choose leaves enough room for the cable under the JCU (refer to the Maritime JCU ICD for dimensions). The magnetic compass safe distance from the JCU is 55 cm (21.7 in).
The JCU can be mounted to the dash in any orientation, using four captive mounting screws that hold panel mounting clamps. When the mounting screws are tightened, the panel mounting clamps rotate and extend away from the JCU at a right angle, and come into contact with the mounting surface. The JCU can be mounted to dash thicknesses ranging from 0.16 cm to 4.45 cm (0.063 in to 1.750 in). A trim bezel snaps on top of the JCU to cover the mounting screws. See
“Installing the Joystick Control Unit (JCU)” on page 10 for detailed instructions.
JCU Connection to Camera
The JCU is a Power over Ethernet (PoE) device and can be connected to the camera directly with a user-supplied cable of sufficient length. In this case, the JCU draws its power from the camera. The video in this case would typically be carried over the coaxial RG59/U analog video cables.
Alternatively, the camera and the JCU can be connected together via an Ethernet switch; this type of configuration allows for more than one JCU or camera to be used. The JCU draws its power through the Ethernet connection, so a PoE injector or PoE switch is required. The video in this case could be provided over the coaxial
RG59/U analog video cables or as IP digital video over the Ethernet cable.
Prior to Cutting/Drilling Holes
When selecting a mounting location for the MV/MU-Series system, consider cable lengths and cable routing. Ensure the cables are long enough, given the proposed mounting locations and cable routing requirements, and route the cables before you install the components.
Use power cables that have sufficient dimensions to ensure safety and video and communication cables that have sufficient dimensions to ensure adequate signal strength.
To ensure a proper seal between the camera unit and the vessel, an O-ring should be installed in the camera base. The O-ring will seal properly with a surface that is flat to within 0.15 cm (0.06 in) over the diameter of the base of the camera. If it is necessary to install on a surface that does not meet this criteria, a marine-grade sealant (3M 4200 or equivalent) must be used rather than the O-ring.
To ensure a proper seal around the JCU, the supplied gasket must be applied to the
JCU and the cutout opening for the JCU should precisely match the template. If the cutout opening is too large, the gasket around the JCU may not cover the opening adequately.

Multiple JCU Camera Installations
In some installations, the system may include additional components, such as additional cameras or JCUs, video equipment, or network equipment. More than one JCU can be used to control the camera, and more than one display can be used to view the video. Also a single JCU can be used to control more than one camera and optionally you can also use a PC to control the camera.
Refer also to the “MV/MU-Series Installation Examples” on page 15 for diagrams
showing several possible system configurations using more than one JCU.
The following diagram shows one possible system configuration using:
• A video amplifier that supports output to four video devices, is used here to provide a single analog video output to multiple monitors.
• POE Injectors for DC/DC Power over Ethernet to power two JCUs.
• Either JCU can take control of the camera and select which video output is shown on both remote monitors (IR, visible, etc).
