Overview--Types of
Playback
Four different playback methods are provided:
Sync Playback (server/local files only): Clips
for a desired time-period from up to 16
cameras on-screen at the same time.
Allows file management including a 'tab' for
each camera.
Note: This applies to local files for cameras in the
current camera folder structure only.
Video Search: Search and playback files
for a desired server, camera, and time-
range. Further search for motion within
video clips. Supports downloading and file
management for the selected camera.
Allows saving single-frame snapshots.
Quad Playback: Search and playback
files for any 1-4 cameras from any server
(not synchronized). Supports preview,
download, and playback. Allows saving
single-frame snapshots.
360 Playback
(optional): Provides the same
features (and uses the same screens) as
Video Search, but with a Panoramic Video
Surveillance (PVS) control enabled to allow
working with panoramic camera images.
7.2
Playback--Technical Details
Play vs. Download: NetVision uses a 'streaming'
playback approach--allowing remote videos to start
playing right-away (without having to be
downloaded 1
st
).
Exception: Due to extremely limited bandwidth,
streaming playback is NOT recommended
through a dial-up connection. Download
instead.
TechTip: Remote (streaming) playback provides
much less 'loading' on the Video Server than
playing the videos on the Video Server itself.
However, it is best to 'download' remote files, and
then play them locally (esp. for pause/resume, etc.)
