HOW TO CHOOSE THE VIDEO STREAM SETTINGS FOR YOUR CONFIGURATION
VMX300(-E) can combine analog and digital video streams for viewing on the VMX300(-E) client. The total number of digital streams that can be
displayed is limited by the size and type of images selected for viewing. Table B identifies the CPU workload and bandwidth amounts used for
each type of video stream.
Table B includes the recommended PelcoNet
™
setting, identified by the gray row. Your selections may vary, depending on system bandwidth
limitations or other restrictions.
Table B.
Digital Video Stream Settings
CAUTION:
System performance will be compromised if the number of video streams is exceeded or if the PelcoNet settings exceed the
recommendations provided in Table B.
Also note that CPU workload could vary, depending on additional system activity that may be occurring at the same time. For example,
using scripts, viewing analog video, or using hyperlinks to change map displays could all affect the CPU workload. It is recommended that
you monitor the CPU workload level under a variety of system conditions while testing your system configuration to identify the optimal
number of digital video windows allowed for your configuration.
Note that if the VMX300(-E) client is operated from a separate workstation (instead of the same workstation running the VMX300(-E)
server), then you may be able to display more digital windows, since the VMX300(-E) client would not be using the VMX300(-E) server’s
CPU.
A NOTE ABOUT MULTIPLE CLIENTS:
If your system requires only one client, the client and server applications can both run on the
same workstation. To optimize system performance in a multiple-client system, each client application should run from a dedicated client
workstation. Additional servers in the same system (VMX300-E only) should be run from dedicated server workstations as well.
