SVPROXY 3 (PROXY/DISTRIBUTOR/DDNS SERVER)
SVProxy 3 is an intermediary server that is somemes
required to relay video and other data between SerVision
video gateways and SerVision client applicaons running
on computers or mobile devices. This 4U rack mountable
server includes a proxy server (SVProxy), a video distributor
(SVDistributor) and a DDNS server (SVDDNS). SVProxy is
required for remote viewing and downloading of video in
special circumstances where direct network connecons
between video gateways and clients cannot be established.
Normally, this occurs when a router or other rewall prevents
clients from connecng to the video gateway. This can happen
when the video gateway connects to the Internet via cellular
modem, and the cellular carrier does not permit direct external
access to the system’s cellular modem. It may also be the case
when the video gateway is located in a private network.
SVDistributor, is an intermediary server that reduces
networking bolenecks caused by too many simultaneous
stream requests from several clients to one gateway, and/or
insucient bandwidth resources. SVDistributor enables up to
1,000 high-quality live video streams (actual number depends
on conguraon and other variables) from a single SerVision
video gateway simultaneously, even when the video gateway
transmits the video via cellular modem. SVDistributor may
be required when mulple users want to remotely view video
from a gateway at the same me without adversely aecng
the quality of the other users’ video stream. SVDDNS enables
users to connect to a gateway using an easy to remember
domain name (DNS) instead of a hard to remember or
dynamically assigned IP address.
SVNVR/SVBACKUP
SVNVR is a powerful server that provides automated backup,
storage, and playback of video recorded by SerVision video
gateways. It connects to the systems at xed intervals,
downloads all the video that was recorded by the video
gateways since the previous download, and stores it on its
large-capacity local disks (3TB standard disk capacity).
SVNVR includes support for wireless networking. In mobile
environments, this versale feature can be used to acvate
downloading of new video recordings in a WiFi zone
whenever a gateway comes within range of the SVNVR server.
For example, if a eet of buses is ouied with SerVision
MVG gateways, and an SVNVR is set up in the bus yard’s WiFi
zone, recorded video can automacally be downloaded from
the buses whenever they enter the yard.
Advanced SVBackup soware oers synchronized playback
of downloaded video from mulple cameras connected to
a single video gateway. Playback can be iniated either by
selecng a start me or by selecng an event from among
those that were detected by the system.
