I.R.I.S. 316 - Manual (Page 10)

7.01 Controlling the Camera
Your camera features positional controls and extended features.
Positional features such as Pan, Tilt and Zoom are usually
controlled via a compatible joystick controller, such as the
IRIS516 or IRIS507 controllers or via a compatible MFD / Chart-
Plotter - sometimes via touch-screen controls depending on the
make and model. Third party control methods may differ from
Iris controllers. For details of compatible third party control
interfaces please contact Iris Innovations. Control of extended
features depends on the type of controller you are using, but is
usually accessed via a menu system on the controller or third
party device (MFD / Chart-plotter etc). If using a third party
control interface consult the relevant user documentation for the
specific equipment for details.
A list of feature commands is included at the end of this
document.
Set-Up Features
The following features will only usually be called during the initial
set-up of the camera following installation:
• VIdeo Standard Set-up.
! PAL / NTSC
When changing the video standard, power the unit down and
then reboot for the adjustment to take place.
• Video Orientation
! UP / DOWN / UP+MIRROR / DOWN+MIRROR
Setting the vertical orientation (UP or DOWN) is determined by
the orientation of the camera (Standard = UP / Hanging (also
known as Ball Down) = DOWN). The mirror option is usually
only used when the camera is facing aft, and is usually only
applied to fixed cameras, as with a PTZ camera such as the 216
or 316, the camera pan position is frequently changing. Video
orientation can however easily be ʻflippedʼ as required with the
IRIS516 controller.
• Set Home Position
!
This feature lets you set the home position of the camera
following install. Usually this is aligned with the bow of the boat.
This calibrates the positional indicator with the direction of the
camera.
Proportional Speed Control (Pan / Tilt / Zoom)
IRIS216/316 Thermal Cameras feature extremely accurate
multi-speed control with a Proportional Speed function that acts
like a gear in order to automatically control speed ratios in
accordance with the current level of zoom. The further the
camera is zoomed in, the slower it will pan and tilt when
commanded and vice versa. This greatly improves control
accuracy when zoomed in.
Auto-Flip
When the camera is tilted past its azimuth the Auto-Flip feature
is triggered. This automatically pans the camera through 180˚ at
full speed (Proportional Control is disabled during this
procedure) to the original pan position and continues the tilt
movement as long as the camera is still being tilted. This
corrects the orientation of the camera module as if the unit kept
tilting past the azimuth without the automatic correction, the
module would be upside down.
Extended Features
Colour Palette Select:
Iris 216 / 316 Thermal Cameras feature multiple colour palettes
which can be used in different conditions and situations to
enhance the image.
• Monochrome (White Hot)
• Red Scale (Red Hot)
• Green Scale (Green Hot)
• Blue Scale (Blue Hot)
• Iron Bow
• Rainbow
• Hot Metal
• High Contrast
• Isotherm
Colour Palette Inverse:
The polarity of the 9 palettes above is reversible providing a total
of 18 colour palettes.
Scene Mode Select:
5 different preset ʻScene Modesʼ are provided to enhance the
image in the following conditions:
• Day Mode
! Default mode. Handles wide thermal dynamic range
! while maintaining optimum picture quality.
• Night Mode
! Normal level/span. Suitable to provide verification of
! vessels/buoys observed with radar or navigation lights.
! The camera handles hot objects in the ! scene i.e vessel
! exhausts and personnel on board decks (of other
! vessels being viewed), without loosing ! d e t a i l o f l o w
! contrast areas.
• Marina Mode
! Ability to distinguish low contrast objects i.e. marina
! pontoons, moorings etc. without hot objects in the field
! of view affecting picture i.e. persons, vehicles on-shore/
! dock or heat from power boats engines.
• Man-Over-Board Mode
! Maximum sensitivity and discrimination of low contrast
! targets/objects. Hot spot tracker (MOB) enabled.
• Fog Mode
! Maximum sensitivity and discrimination of low contrast
! targets/objects.
Video Pause
Freezes / Unfreezes the image in order to study an on screen
artifact.
Non Uniformity Correction Control (NUC)
Manually operates shutter in order to recalibrate the thermal
sensitivity. When the shutter closes, the camera re-calibrates itʼs
temperature threshold to the uniform temperature of the shutter.
Non Uniformity Correction (or NUCʼing) also occurs
automatically to maintain a sharp image.
