Close All Tasks on Download:
Prevents the unit from performing any other jobs – accepting new
connections, streaming live or recorded video, recording video, or downloading other video – when
downloading is in progress.
Block New Connections while Downloading:
Prevents the unit from accepting any new connections from
clients while downloading of recorded video is taking place. When this option is selected, transmission of new
live or recorded video streams to client applications does not begin while downloading is underway, but
existing streams are not closed. When this option is not selected, the process of downloading may take
somewhat longer to be completed. In addition, the framerate of video displayed in the client may be reduced at
times while the download is in progress.
Disable TV-Out While Downloading:
If a CCTV monitor is connected to the Video Gateway, stops
streaming of video to the monitor while downloading of recorded video is taking place
Additional System Settings
A number of other system settings can be configured in the
General System Settings
screen:
Video Authentication:
Adds a digital signature to each frame of video captured by the system. This signature
makes it possible to identify frames that have been tampered with. When a SerVision client application plays
video that has a digital signature and discovers a frame that has been changed from its original state, the status
of the stream indicates that the stream was modified. (Note: Only the current versions of SVMultiClient and
the Player support this feature.)
Outline Switching:
Defines whether the system can activate different outlines automatically and, if so, what
type of trigger will cause the system to switch to a different outline, sensor events (from Sensor 1) or a
schedule. If neither type of automatic outline switching is selected, you can manually change the active outline
at any time. For additional information, see
Network Speed Optimization:
Activates zero-latency handling of video packets. Activating this option may
increase the transmission speed of video from the Video Gateway to client PCs that are on the same LAN as
the Video Gateway. This feature is not recommended for use with other types of client connections (internet,
cellular, etc.). In addition, it is only recommended for use if video transmission speed is problematic. It usually
has a more marked effect on video streaming than on video downloading.
Network TCP Optimization:
Opens all sockets with TCP_NODELAY activated. Activating this option may
increase the transmission speed of video from the Video Gateway to client PCs that are on external networks –
internet, cellular, etc. This feature is not recommended for use with clients that are on the same LAN as the
Video Gateway. In addition, it is only recommended if video transmission speed is problematic. It usually has
a more marked effect on video streaming than on video downloading.
SMS on System Start:
Sends SMS notifications to all SMS recipients whenever the Video Gateway starts
running. For information about defining SMS recipients, see
ADAM Sensors:
Enables the activation of sensors that are connected to the Video Gateway unit through an
ADAM module. For additional information, see
Configuring Sensor and Activator
IA Sensors and Activators:
Enables the activation of sensors and activators that are connected to the Video
Gateway unit through an IA 3126-2 relay board. For additional information, please refer to your unit’s
installation manual.
Maximum Recording Length:
Automatically erases recorded video after a specified period of time.
Publish System Name:
Sends the name and IP address of the Video Gateway to the ARP system of the local
network so that the ARP system can translate the name of the Video Gateway to its IP address. This enables
local users to access the Video Gateway using its name.
Ignore VGA in RT:
Tells the Video Gateway not to send VGA video streams (of live or recorded video) to
client applications; when a client requests a VGA stream, the stream is sent in a lower-resolution, although the
VGA image size is retained. Activating this option enhances the stability of the stream when bandwidth is
limited, such as when the Video Gateway transmits video streams over a cellular connection. This option does
not affect video downloading; video can be downloaded in full VGA resolution even if this option is selected.
