System Installation

• 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.
• The M400 camera has a “forward” direction adjustment which has been set at
the factory. This is the direction directly toward the front of the vessel. Icons on
the video show the direction the camera is facing in relation to an outline of a
ship. Refer to the latest Interface Description Document for details. After
installation, the forward direction of the camera must be verified and adjusted if
required. Refer to M400 Operator’s Manual (FLIR Doc. # 432-0012-00-10).
Note: When the camera is mounted upside down (ball down), the camera base must be rotated
backwards, to point toward the stern of the vessel.
• 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 9 G transverse and 15 G vertical. Improper mounts that are
loose and/or resonate can magnify vessel impacts causing the camera to be unable to maintain
pointing direction.
• When selecting a mounting location for the M400 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 1.5 mm
(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.
• A final location consideration is the relation between the camera and other navigation devices.
If relying on a magnetic compass for navigation and direction, 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 40 cm (15.7 in).
System Installation
In most installations, the M400 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 O-ring.
Use a thread-locking compound such as Loctite 262 or equivalent with all metal-to-metal threaded
connections.
Caution: Use all six mounting holes to secure the camera rigidly.
As an alternative to a mounting O-ring, you can use a marine-grade sealant such as 3M 4200 or
the equivalent.
