DETEXI NVR 30 - 169
DETEXI Client Archive Tool vs. DETEXI Archive Viewer
The DETEXI Client Archive Tool pulls recorded video from the NVR archive transferring all frames in
the time segment selected into
local memory. For this reason, the amount of video that can be
viewed at once is limited, and the initial load time is very affected by the network the video is being
pulled across. Once loaded, however, this video can be viewed very quickly and efficiently at very high
frame rates. When users already know the
time and date of interest and only need to review a small
amount of video, they might find the DETEXI Client Archive Tool more efficient than the DETEXI
Archive Viewer.
When large amount of video need to be scanned for events the DETEXI Archive Viewer is the tool of
choice. Rather than loading a collection of video into local memory, the Archive Viewer streams
video directly from the NVR archive over the network. For this reason, a full 24 hours of data is at the
user’s fingertips for viewing at all times without requiring a large initial load time. However, this limits
user to slower possible playback speed — completely dependent upon the network connection
between the Archive Viewer and DETEXI NVR archive. It is not uncommon to see pauses in video
playback for buffering of the video stream.
9 When located on the DETEXI NVR computer, the DETEXI Archive Viewer is very
efficient — limited only by the read speed of the hard drive and decoding speed of
the video card.
Security
An important part of network video management is security. The DETEXI NVR enables the Remote
DETEXI Client connection to any authorized DETEXI NVR available anywhere on the Internet or corporate
network for remote viewing and control.
