PLAYBACK
Once you’ve selected your video(s), you can control the playback in the same manner as
using a VCR or computer’s media playback software. The playback interface includes features
that add an extra level of control, including the ability to play in reverse as well as forward,
frame-by-frame movement and multiple playback speeds. Certain buttons will be grayed out
depending on the playback mode.
Double-clicking on a screen in a multi-channel display format will switch to a single-channel
display. Double-clicking again will enlarge it to full screen mode, hiding the Search area on the
right and the Video Indicator and Progress bar below, although the latter will pop up if the
mouse is moved to the bottom of the screen. Double-clicking a third time will revert back to
the multi-channel display mode that you had selected. Right-clicking when in single screen or
full-screen mode will reverse the process. Right-clicking while in your original viewing mode will
end the video playback.
In most circumstances, the control buttons affect the video on all screens in a multi-channel
display. Unchecking the Sync box at the bottom of the screen will allow independent control
of each channel. In this case, the controls will only affect the screen highlighted in green. Click
once on a camera’s view to select that channel. It should also be noted that certain functions
only work - or work best - in single-channel viewing mode.

Start, Stop and Play
Clicking either of the Play buttons will start the playback in the desired direction. The button’s
icon will change to a Pause icon to allow you to freeze the playback as needed. If you have
Sync unchecked, clicking Stop will end the playback of the video in the selected screen
while any other videos will continue to play. Otherwise, Stop will end the video playback on all
screens.
Frame Advance/Reverse
These buttons are only active when the playback has been paused. They allow you to move
forward or backward in 2-second increments.
Slow/Fast Play
There are four speed settings for each button. Clicking these buttons will increasingly slow
or speed up the playback as appropriate. When the after the fourth setting is reached, a
subsequent click will return the playback to normal speed. You can also decrease the effect of
one button on speed by clicking the other. Example: With playback set on “Fast 3”, you can
slow it down to “Fast 2” by clicking on the Slow Play button.
Volume
If you have a microphone-equipped camera or a microphone co-located with your camera you
can play back any audio that was recorded along with the video. Adjust the volume with the
slider as needed.
