• The Track tab (under File or shortcut button on toolbar) allows the user to appoint

an upstream direction for the fish and enter a site identification number (Figure ).

There is then an option of using the PC clock or entering an avi start time to

determine the fish time. The PC clock would be used if the PC and DVMD were

deployed on site and collecting in ‘real time’, which would be the usual way of

using the DVMD. However, some initial calibration of the DVMD parameters

would be required and this would be carried out using another PC to play back a

video file from the site through the DVMD. There is an option to enter a start date

and time for the video file and a playback speed. Normal speed is 25 frames per

second. This information is then used to determine the time of any fish tracked.

• The video display screen can be turned on and off by clicking Video Display in

the View menu.
