Requesting video from many cameras
Since images from many cameras may need a few seconds more to appear, retrieving
video from many cameras at once offers images from slightly before the top of the
minute of the “Go to time” you request. For examples, see table 11.

* On systems connected to many cameras, selecting one of the higher numbered
cameras also slightly pushes back the time of the first image obtained.
3.3 Resolution of Recorded Video
Optimal size for camera windows in a Retrieval
During a Retrieval session, an operator can size camera windows optimally for the
resolution at which recording was made.

!45 To size a camera window optimally for a resolution
1. While running a Retrieval session, right-click on a camera window’s video. A
small window appears on the video listing Image Size. See figure 31.
2. Click the value that matches the “Recorded at n × m” value. The menu
vanishes and the camera window is sized optimally.
Recorded video cannot be retrieved at a higher resolution than the one at which it
was recorded.
Video is recorded at one, set resolution, which can be lower than those viewed in a live
session. The resolution for recorded video is chosen by your organization’s Multi SA.
