222 Playing Back Recorded Video/Audio XX112-36-00 Rev 909 Kollector Hybrid Network Digital Video Recorder
Overview
The ViconNet system enables you to select and play back recorded video and audio segments that have
been stored in defined storage locations. You can play back data that has been recorded either on your local
Kollector or on other remote Workstations in your ViconNet system. In addition, you can play back data that
was recorded manually or that was recorded automatically as a result of an alarm event or a preconfigured
schedule.
In order to play back recorded video and audio, in the Navigator window, you must select the devices that you
want to play back according to the corresponding number of display locations. Then you can select the
playback time interval and start time according to the recorded segments that you want to play back.
When you have synchronized all the options in the Navigator window, you can display and play back the
selected segments simultaneously or individually in the Main window, as required.
Picture quality (resolution) refers to the compression level of the video images. The quality of the recorded
image is determined according to configuration settings, with eight degrees of quality that can be assigned.
The following settings are for ViconNet cameras only (third party cameras may vary):

Less clear picture quality, faster data transmission.
The view image quality is also a function of the selected display mode. The Single mode is automatically
assigned the highest resolution available. In order to improve transmission speed, other modes are
automatically assigned lesser resolutions, in proportion to the number of views selected. In general, the
smaller views (for example, 9 or 16) do not benefit from higher resolutions and are equally legible in a lower
resolution.)
The ViconNet system also provides some optional functions that can be used when playing back recorded
video and audio. These include viewing alarmed segments of recorded data and creating archives that
contain specific recorded data, if required.
