will point to the newer BWC heading for an additional dwell time 
period. When the camera is in the Slew to Waypoint mode, this icon is 
continuously displayed:
Radar Tracking – When Radar Tracking is enabled, the camera 
will track selected radar targets using data from NMEA Target Tracking 
Message (T TM) information provided by the radar unit.
Th  e user can select up to 100 targets to be tracked by Voyager II (refer to 
the radar or GPS documentation on how to designate a target). Once one 
or more targets are selected, the Voyager II will point toward each target 
sequentially, and track the target using position data that is sent from the 
radar unit. 
Th  e camera points at each target for a pre-set amount of dwell time (10 
seconds by defau lt) before mov ing on to t he ne x t ta rget. Th  e time spent on 
each target can be changed by selecting the menu function Dwell Time 
and using the joystick to toggle through the available presets. Th e default 
v a lue is 10 second s. Th  e Dwell Time includes the transition time from one 
target to the next.
Once the Voyager II begins to sequentially track the selected target(s), 
if desired the user can override the automatic scan by using the joystick 
to point the camera in a diff erent direction. Once the user releases the 
joystick, the camera will return to tracking its targets 10 seconds after the 
last JCU input (buttons or joystick). 
When the camera is in the Radar Tracking mode, the icon shown below 
is continuously displayed:
NOTE: Due to the way radar operates, it is possible to lose a 
target momentarily. To ensure that the tracking process continues after 
the momentary loss of a target, the T TM function maintains the last 
known position of the target in its queue for 60 seconds after receiving 
the last valid message. After the 60 seconds has lapsed, that target is 
removed from the queue. 
						

							32
Th  e ability of the Voyager II to accurately track a target depends on the 
quality of the data sent from the radar unit. Th  e ability of the radar to 
eff ectively track a target is infl uenced by several factors, such as the make 
and model of the radar unit, the radar update rate, the relative angular 
rate of the target, the angular rate of the boat heading and the velocity of 
target being tracked. 
NOTE: It is important to enter the accurate mounting height of the 
camera above the water line to ensure the unit’s pointing accuracy for 
close-in targets. 
While the Voyager can track a large number of targets, it is important to 
understand that in practical terms the number of targets is linked to the 
Dwell Time. Since the Voyager looks at each target for a minimum of 10 
s e c ond s  b e for e  mov i n g  on  to  t he  ne x t  t a r g e t ,  it  i s  p o s s ible  to  s e t  up  s o  m a ny  
targets such that it will take too long to cycle through all of them for the 
information to be of any use to the operator.
Message Priority
 – In the case where you might have a need 
to enable more than one NMEA feature at a time, please keep in mind 
there is a set priority to the order in which the Voyager II responds to the 
diff erent NMEA messages. Th  e priority order is:
1. JCU input (joystick or buttons)
2. Radar Cursor Tracking (RSD)
3. Slew to Waypoint (BWC)
4. Radar Tracking (T TM)
For example, if the unit is “ listening” to BWC or T TM messages and 
looking at a particular target, and it receives a RSD message, the Voyager 
will wait until the end of the dwell time and then move on to the RSD 
message, ignoring all other input.
Dwell Time – Dwell Time is the time spent on each tracked target. 
Th  e default value is 10 seconds but you can change it by toggling through 
the diff erent time options, with a possible range of 10 to 60 seconds
Mount Height
 – Mount Height refers to the physical height of 
the camera above the waterline, in meters. Th  is is important because this 
distance is used for target triangulation and incorrect values will aff ect the 
camera’s tracking performance.  
						

							WEBCAM FEATURE 
						

							34
WEBCAM
It is possible to use Voyager II as a Webcam, allowing you to keep an eye on your 
vessel from anywhere in the world using an Internet connection. 
Th is section 
describes the IP interface that allows monitoring and control of the 
Voyager II from remote locations.
BEFORE YOU BEGIN
Using the webcam feature from a remote location requires an Internet 
c on ne c t ion w it h a s t at ic I P a dd r e s s , or at le a s t a n I P a dd r e s s t h at i s k now n . 
If the IP address is not static, then every time it changes the webcam 
feature will need to be reconfi gured.
Th  e webcam capability may require a signifi cant amount of confi guration 
of network equipment that is completely independent of the Voyager II 
camera. Getting it set up and working may require a level of familiarity 
with managing IP networks that is beyond the skill set of many people. 
Prior to confi guring the webcam feature, make sure you know how to 
manage and confi gure the other equipment in the network (for example, 
whatever cable, DSL or wireless modem/router that is used to connect to 
the Internet). FLIR technical support can only provide limited support in 
this regard. 
CONFIGURATION STEPS
Confi guring the Voyager II webcam feature involves the following steps:
Connect the Voyager II to a PC and verify IP connectivity 1. 
If needed, confi gure the PC web browser to allow installation of  2. 
the ActiveX component (VLC video player) 
Access and use the webcam feature locally with the PC 3. 
Change the Voyager IP address to match the local network on the  4. 
vessel
Confi gure the Voyager to allow the video to be streamed to an  5. 
external IP address
Test the webcam feature remotely over the Internet 6. 
IP CONFIGURATION
Th  e IP address for the Voyager II must be statically confi g ured; it will not 
obtain an address off  the network automatically with DHCP. In order to 
set the IP address on the camera, it will be necessary to temporarily set up 
a PC with an IP address on the same network as the Voyager II default 
IP address.  
						

							35
For example, confi gure the PC to have an IP address of 192.168.250.1. 
Th  en connect the PC and the Voyager II to the same network, or even 
back-to-back with a cross-over Ethernet cable.
If the network makes use of Network Address Translation (NAT) and 
port forwarding and/or a fi rewall, the webcam feature requires that 
certain ports are opened up to allow access to the camera control and 
to allow for video streaming. In particular, the following ports are used 
by default:
Por t Protocol Comment
TCP Port 80
HTTP • Web browser access
TCP Port 8080
HTTP • webcam
TCP Port 554
RTP • Video streaming
In most installations, the IP address for the Voyager II will be changed 
from the default address (192.168.250.116) to a diff erent IP address that 
is within the address space of the existing IP network on the vessel. For 
example, there may already be devices such as IP cameras, PCs, and 
routers that are attached to a local area network (LAN). In this manual, 
we will use the 192.168.1.0/24
1 network as an example for the existing 
network, and the Voyager will be added to that network. 
Th  e IP address for the Voyager II will be modifi ed using a web browser 
such as Internet Explorer. After the Voyager is powered on, point the web 
browser of the PC to the default IP address by typing “192.168.250.116” 
in the location fi eld.
1 Th  e 192.168.250.0/24 designation of the net work is known as CIDR notation; 
it indicates the range of net work addresses that use 192.168.250 in the fi rst three octets 
with a netmask of 24 bits (255.255.255.0). 
						

							36
Th  e web browser will display a picture of the Voyager (the label at the top 
will indicate PTZ35x140) as shown below. 
When this screen appears, the PC is successfully connected to the camera 
over the IP network. We will return to this login page later in order to 
make confi guration changes to the camera. First however we will test the 
webcam with the existing default confi guration.
ACCESS THE WEBCAM LOCALLY
Prior to changing the IP address of the Voyager II, at this point it may 
be wise to bench test the webcam feature using the local network. Th e 
webcam feature is also accessed by using a web browser. Th e instructions 
that follow describe how to use the webcam with the Microsoft Internet 
Explorer browser. 
Important: Please refer to the Web Browser Confi guration section for 
information on how to confi  g u re t he sec u r it y set t ing s in Inter net E x plorer 
and on how to use other browsers. 
In the web browser, connect to the following URL (the port number 8080 
is required): ht t p://192.168. 250.116:8 08 0/operation.htm l
Th e fi rst time you connect to the webcam, the following screen will 
appear. Note the IE Security notice at the top of the screen indicating 
an attempt to install an ActiveX control. Th  is is the VLC video player 
that is needed to stream video from the camera. You will be prompted to  
						

							37
install the VLC Player2 and the Voyager camera will download the ActiveX 
software to the computer .
Right click on the warning, and install the ActiveX control. 
It may take a moment for the video to start streaming. Confi  rm that video 
is streamed to the monitor and it is possible to control the camera using 
the pan/tilt controls and so on. For example, switch between Black Hot 
and White Hot. 
Additional information on how to use the Webcam interface is provide 
in the following section entitled Camera Control. Once operation of 
the camera has been confi rmed, the camera can be confi gured to allow 
webcam control remotely over the Internet. 
Note: the camera streams video from either thermal camera (wide or 
narrow fi eld of view). It is not possible to stream the daylight video or the 
combined wide and narrow thermal video.
 
2 Please note that currently the Voyager II only supports the VLC Player v. o.8.6.f 
						

							38
CAMERA CONTROL 
Th  e Webcam graphical user interface (GUI) allows you to control the 
camera’s pan and tilt motion, change between wide and narrow fi elds of 
view, change the imaging mode from red/white-hot to gray/white-hot and 
set diff erent levels of contrast.
To control the camera movement, use the arrow button 
. 
Please note the following: 
Pressing the single arrow  • 
 and releasing the mouse button in less
  than one second lets the camera move one step (1/3 or ¼ of FOV). 
Pressing and holding the single arrow allows the camera to move at  • 
  1/10 FOV /second. Releasing the mouse button stops the movement. 
Pressing the double arrows  • 
 produces the same results but at two
  times the speed (steps and speed). 
Double clicking on the symbol in the upper left portion of the GUI  • 
  will make the camera turn in that direction.
NOTE: Th  e Home position cannot be changed through the GUI. 
When 
you click on Home, the camera will return to the last saved position. 
Changes to the Home position must be made on site (on the vessel).
Image Mode Control – Click the Night button to toggle 
between red (night) and gray (daytime) modes.
Same image with diff  erent color modes - White/Hot Night (left) and Day 
(right) color modes
   
						

							39
Image Contrast – Under Contrast Mode you have four preset 
options: Night Underway, Night Docking, Day, and Man Overboard. It 
is advisable that you fi nd and select one that produces the best image for 
your needs for the current environmental conditions.
Black / White Hot – If you select White Hot, hot objects are 
displayed in white, cold objects in black, with the color gradient between 
them indicating relative temperatures between hot and cold. Selecting
Black Hot reverses the image and hotter objects are now displayed 
in black.
Field of View (fov) Control – You can change between 
Wide and Narrow fi  e ld of v ie w (s e e fi  gure below). Th  e Focus function only 
applies to the Narrow fi eld of view.
Focus Control – When the Narrow fi eld of view is selected 
you can use the Near/Far/ buttons to manually focus the camera. Use 
the Far button to “pull back ” on the focus function, and the Near 
button to focus in. Using the Near/Far buttons instead of just using the 
Auto focus button will speed up the focusing process.
Full Screen Video – If you wish to view the video in full 
screen mode, double-click on the image. To exit the  full screen mode, 
double-click on the image again.  
NOTE: No icons are displayed on the MPEG video stream. Refer to 
the graphic to the left of the video for azimuth control, which indicates 
the direction the Voyager is pointing relative to the bow of the vessel.

REMOTE ACCESS
Th  e webcam feature is designed to allow access to the camera remotely 
over the Internet. For example, the following diagram shows a typical 
scenario. Th  e laptop in a remote location would be used to connect to 
the Voyager II over the Internet. It is assumed the Router/Gateway will 
perform Network Address Translation (NAT) and port for warding. 
Th  erefore it is necessary to confi gure the following items on the Voyager 
II: 
IP address on the local network (in this example, 192.168.1.116) 1. 
Defau lt gateway (192.168.1.1) 2. 
Video devices such that video streams are sent to the external IP  3. 
address (12.164.25.1)
Note: Once the camera is confi gured for remote access from the remote 
PC through the Router/Gateway, it is not possible to access the webcam 
feature from the local PC (192.168.1.10 in the example above).
IP CONFIGURATION
To add the camera to the local network, it is necessary to log into the web 
confi guration pages with the browser, and then change the camera IP 
address to match the local network. Point the web browser of the PC to 
the default IP address again by typing “192.168.250.116” in the location 
fi  eld. In the screen with the picture of the Voyager II, enter the User name 
“admin” and Password “indigo”, and then click on the Login link. Th e 
General Settings screen will be displayed as shown below. Click on the 
LAN Settings tab on the left.
SECURIT Y WARNING: in order to protect against 
unauthorized access to your camera from other internet users, you 
must take steps to protect your connection. FLIR recommends that 
you set up a fi rewall on your router.
