3.01 Examples of Typical Systems
A basic configuration will consist of a single camera, a camera
controller and a viewing medium (either a dedicated video
monitor or a multi-functional display (MFD)). The video feed
from the camera is routed directly into the MFD, and the control
data from the joystick is sent directly to the camera.
Systems become more complicated where there are multiple
cameras, monitors and/or controllers and where more complex
video and data transmission methods are employed such as
wireless or Internet Protocol (IP) conversions. The diagrams
below detail a number of different connection configurations.
In theory it is possible to have up to 255 controllable devices in a
system (cameras or controllers) and unlimited fixed cameras,
but this is obviously dependent on the video switching
equipment installed, the camera control data management and/
or the vessels on board LAN - and of coarse the size of the
vessel!
The key issue when installing multiple controllable cameras is
that they have individual addresses (see below). A popular
configuration would be something along the lines of 2 x
controllable cameras, 4 x fixed (static) cameras and 2 x
controllers. This would mean that the number of video inputs
required would exceed the amount of inputs offered by most
chart plotters and so a video switcher (such as the IRIS606 c
Camera switcher) would be required. Video from each camera is
routed into the video switcher and the output from the switcher is
then routed into a single input of the chart plotter. Switching is
controlled by a dedicated waterproof keypad connected to the
switcher. The data wires from each of the controllable cameras,
along with the data wires from the two controllers would then
need to be routed into a Serial Data Distributor (also known as
an Expander), such as the IRIS EXP0204. This simplifies
installation and prevents ʻcross-talkʼ and ʻreflectionsʼ and the
data line that can result in poor camera control and ʻover-runsʼ.
