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 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)
IRIS116 series 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
Video Pause
Freezes / Unfreezes the image in order to study an on screen
artifact.
User Presets
The camera has a built in memory that can be used to store up
to 100 user ʻpresetʼ positions. A preset allows you to move the
camera to a favourite or important position and learn that
position so that the camera can be instructed to move at top
speed to that position at the touch of a button. For example, you
may want to point the camera so that itʼs facing directly aft so
you can take a look at whatʼs coming up behind you. By saving
this position as a Preset, you can send the camera back to this
position immediately by recalling the preset. Presets can also be
used to form ʻToursʼ, where the camera can be instruction to
step through each preset within the Tour in sequence with a pre-
determined dwell time between each position.
User presets are numbered 100-199. Usually the controller you
are using will have the ability to SET a Preset to learn the
position and then CALL a Preset to send the camera to that
position. This will depend on the model of controller you are
using. Consult the user guide of your controller for details.
System Presets
Certain functions of the camera that are not defined by the
Pelco-D Protocol are called by using Presets. A list of System
Presets can be found later in this document.
Scan Modes
The camera supports 4 different Scan Modes. Once activated,
tilt and zoom commands are still accepted by the camera but
you will not be able to pan the camera until the Scan has been
Stopped:
• 45˚ Auto Scan
# Camera pans back and forth 22.5˚ either side of the
# centre point (the position the camera is facing when the
# scan is activated.
• 90˚ Auto Scan
! Camera pans back and forth 45˚ either side of the
# centre point (the position the camera is facing when the
# scan is activated.
• 180˚ Auto Scan
! Camera pans back and forth 90˚ either side of the
# centre point (the position the camera is facing when the
# scan is activated.
• 360˚ Auto Scan
! Camera pans continuously through 360˚, pausing every
# 108˚.
There are three speed controls for each Scan. Slow, Medium
and Fast.
A command is also available to ʻRe-Centreʼ the scan. This can
be found in the command list.
