Chapter 3 –Video Explorer
3.4 Play

Once you have a video segment selected, trying to look at single frame is seems a slow process to get it
at the correct time. So much like a Video recorder, the software has a very simple to use set of
playback tools.
Firstly as soon as you are in the video explorer, you can use the Keyboard Cursor Up, and cursor down
keys to change the current active camera a single frame at a time. Note that because different cameras
are recorded at different times, the other cameras can jump more than one frame, or as you may notice
the times are not all exactly the same. This is because the system is trying to match a time line against
the current active camera. And the system only records when the motion detection is activated. This is
normal and is by design; after all there is no point recording information when nothing has changed. So
in essence you are shown the last recorded frame at each of the other cameras.
The same frame forward and back process can be done if you have a “Scroll Wheel” mouse on your
system, by using the scroll mouse button. This is very simple and a quick way to find a frame. And
again makes the keyboard not seem part of the system.
Animation playback is achieved using the very simple set of control Icons at the Top right of the
screen.
Once you use them you’ll see it’s easier than setting your home VCR clock time.
Click the Play
Icon, and the system will start playing through the video segment. The status of
playback is indicated as the Icon changed to the standard green background, like this
as normal
clicking again will de-activate the playback.
Note that you still can zoom into the segment and go back and forth; the system will just keep playing
what is the selected video segment. Normally you’ll just stop the playing.
The normal playback tries to playback in real-time as recorded, which is naturally very slow. To speed
up this playback you need to select the
Icon. This changes to green.
Again as normal
clicking again will de-activate this.
Clicking the
Icon, the system will pay naturally in reverse. Again green when active
As soon as you select either play – reverse Icons, the stop Icon will be available to select.
This as you would expect will stop all the playback activity.
You’ll notice on the playback a white line which moves. This it is the marker to the point which is
being played. When this marker reaches the bottom of the segment, the system will either select the
next segment, or start the playback again from the top of the current selection. If you look at the
options menu on the previous page, you’ll see the
“Play Loop”
at the bottom, this define what the
system will do with the playback. Having a tick against the option the system will re-play the current
segment.
