CamTrak for OziExplorer
Track camera positions on the your camera's audio track
On the camera, a small device (pictured above) is required to interface the
GPS to the camera. This device will constantly store the GPS positions on
one of the audio tracks of the camera. Our device plugs into almost any GPS
receiver, and has an audio output that can be plugged into one of the audio
channels of a Video camera.
What sets our system apart from others is that we do not place the position
information on the screen, but store it on one of the audio tracks.
Whilst most video cameras have two or four channels, there is rarely any use
for more than one channel.

FAQs
Wireless |
| Q: Can I use CamTrak with a wireless video transmitter? |
A: In most cases there is no problem with this. This is actually the type of
application that CamTrak was designed for. All you need to do is to plug
the output of the CamTrak into one of the audio inputs of the the video
transmitter, and then plug the output of the reciever into the computer at
the recieving end. |
Technology |
| Q: When I play the video I recorded back, I hear a horrible noise on one of
the channels |
A: This is normal. This is the computerised recording of the GPS positions and
needs to be there for the system to work. You may be able to get arround
this problem my playing back only the other channel through your sound
system. |
Mapping |
| Q: What maps do can I use with this system? What maps do you supply? |
A: Almost any raster format of maps can be used with the system. We do not
supply any maps. It is up to the user to buy the maps, and also the
OziExplorer mapping software |
OziExplorer |

CamTrak Software
CamTrak Basic contains software to allow stations to be tracked using
OziExplorer whilst a video is being played back. CamTrak Basic Player is free.
CamTrak Live contains software to allow stations to be tracked using
OziExplorer whilst a video is being played back. The audio output containing
the CamTrak position information gets plugged into the Line Input of your
computers sound card, and the software sends the information to your copy of
OziExplorer.
CamTrak Pro is similar to CamTrak Basic, except it also contains
hardware to decode CamTrak position information without the issues involved
with using the sound card. The extra hardware plugs into the serial port,
and then into the video recorder.

System Overview
CamTrak Encoder
The CamTrak encoder is connects between the GPS receiever and the video
camera. It requires at least 5V power. The output of the CamTrak Encoder
plugs into the audio input of the video camera. The serial output of the GPS
plugs into the CamTrak Encoder
CamTrak Decoding
There are a number of ways to decode the CamTrak signal. In order to decode
the CamTrak data, we need to get the video and audio signals off tape. This
can be done through Firewire, video digitizing hardware or the sound card in
the case of the audio signal.
Live Mode is where the tape is played back on a normal VCR unit (or video
camera) with
the video being sent to a video screen. The Audio Track is sent to the
decoding computer, either in to the Sound Card or Hardware Decoder. In live
mode image is displayed on the TV and the map on the PC.
Recording Mode. The first step is to digitize video from the video
tape using the normal video digitizing tools. Care must be taken to
preserve the video levels. Once the file is digitized to a WMV file, the
file can then be loaded into CamTrak. When the file is loaded in, the file
can then be encoded in CamTrak either using the Sound Card or the CamTrak
Decoder.
The decoding process invloves playing back the video on the computer in real
time, and decoding the signals recorded on the audio track. Using the
hardware solution, the decoder is plugged into the serial port and the audio
output of the PC, and the data is saved with the WMV file.
CamTrak Editing
Video Tapes that have been recorded with CamTrak can be edited together with
on any video editing system. Care must be taken to ensure that the audio
tracks are not edited out during the process. Following editing the video
tape can be digitized like normal.
