SerVision Embedded Video Gateway System Guide
Getting Started 5
Getting Started
SerVision’s embedded Video Gateways are compact Video Gateway units that provide state-of-the-art security
functionality for a wide range of environments, from offices and homes to vehicles and other moving platforms. All
units feature live video streaming, video recording and playback, motion detection, sensor management, and real-
time event notification and device activation. These features can be accessed remotely via PC, PDA, or cellular
telephone.
All Video Gateway units can connect to computer networks, including local networks and the internet, using cable-
based Ethernet connections. Some models also support wireless network connections via cellular networks and
WiFi. In addition, mobile models support GPS tracking, and can be integrated with some third-party fleet-
management systems.
The following embedded Video Gateway models are currently available:
HVG400: A four-channel Video Gateway optimized for homes and small offices. The HVG400 features a
built-in hard drive capable of storing large quantities of recorded video and supports a cable-based connection
to a network.
UVG400: A four-channel Video Gateway that is ideal for deployment in locations where cabled network
connections are not available, such as building sites, parking lots, and horse stables. The UVG400 can connect
to a network via Ethernet, cellular, or WiFi and contains a built-in hard drive capable of storing large
quantities of recorded video.
MVG400:A four-channel Video Gateway designed for deployment in vehicles such as buses, trains, and
delivery trucks. The MVG400 contains a removable hard drive capable of storing large quantities of recorded
video. It can connect to cellular and wireless networks, and also supports GPS that enables remote users to
locate and track the vehicle in which it is installed.
MVG200: A two-channel Video Gateway designed for deployment in smaller vehicles such as cars, vans, and
mini-buses. The MVG200 records video and other data on a removable SD card. It can connect to cellular and
wireless networks, and supports GPS tracking.
CVG: A compact, two-channel Video Gateway optimized for streaming live video from indoor locations. The
CVG stores video and other data on a removable SD card, and can connect to cable-based networks.
CVG-M: A compact, two-channel Video Gateway optimized for streaming live video from vehicles. The
CVG-M can connect to cable-based and cellular networks, and also supports GPS that enables remote users to
locate and track the vehicle in which it is installed. It stores video on a removable SD card.
About this Guide
All Video Gateway models are configured using a browser-based configuration utility that is accessed via PC. This
guide explains how to use the configuration utility to configure and manage an embedded Video Gateway unit. The
guide assumes the unit is already installed in its intended location, all required devices are connected to it, and it is
connected to a power source and a network. For information about installing your Video Gateway unit, please refer
to its installation guide.
The following topics related to the configuration utility are covered in this manual:
Configuring the unit (page 8)
Connecting to the unit to check that the configuration settings are correct and to view video, snapshots, or
event information (page 163)
Resetting the unit (page 197)
Diagnosing system problems (page 171)
This guide also includes information about system maintenance and handling problems:
Upgrading the firmware (page 183)

SerVision Embedded Video Gateway System Guide
Getting Started 6
Restoring the factory settings of the unit (page 198)
Troubleshooting (page 201)
Most embedded Video Gateway models can be used in conjunction with a CCTV monitor. The monitor can be used
to view video from the cameras connected to the unit. Instructions for viewing video on a CCTV monitor are
included in an Appendix to this guide (see Appendix A: Viewing Video on a CCTV Monitor (TV-Out), page 207).
Because this guide relates to a number of different embedded Video Gateway models, certain parts of the manual
are only relevant to specific models. Information that only relates to some of the models is color-coded in teal. For
example, a paragraph that is only relevant to the MVG200 and CVG-M models would appear like this:
This is an example of a paragraph that only relates to the MVG200 and CVG-M models.
If an entire section is only relevant for particular models, the beginning and end of the section is marked and labels
appear at the top of the section. The labels indicate the models for which the section is relevant. For example, a
section that is only relevant to the MVG400, MVG200, and CVG-M models would appear like this:
GPS
Only the MVG400, MVG200, and CVG-M models support GPS position tracking.
The features of the two MVG models, MVG200 and MVG400, are nearly identical. For this reason, they are often
refered to collectively as the "MVG." Similarly, a single label may be used to represent both models:
Figure 1: Label representing both models of the MVG collectively
Because the Video Gateway models have slightly different features, their configuration is different in some cases.
Screenshots of the configuration utility that appear in this guide may be from a different model than the one you are
configuring, and may therefore not exactly match the screens you see. If the screen that is displayed differs
significantly from model to model, the name of the model from which the screenshot was taken appears in
parentheses in the caption below the screenshot.
About Client Software
Client software is used for accessing the Video Gateway unit remotely in order to view video and events and control
the system in various ways. This guide includes a general overview of SVMultiClient, SerVision’s PC-based client
software. A complete user guide for SVMultiClient is available on the SerVision website
(http://www.servision.net). SerVision also offers client software for certain cellular telephones, tablet PCs, and
PDAs. These applications, and user guides for them, can be downloaded from the SerVision website. In addition,
SVControlCenter is a complete control-center solution that includes powerful client features, for enterprises
managing sizable numbers of Video Gateways. Additional information about SVControlCenter is available on the
SerVision website and from SerVision customer-service representatives.
Before You Begin
Before the Video Gateway unit can be configured, the hardware should be set up as follows:
The Video Gateway unit should be installed and connected to a power supply. (Installation guides for all
Video Gateway models are available on the SerVision website.)

SerVision Embedded Video Gateway System Guide
Getting Started 7
All the cameras and optional devices (sensors, activators, etc.) should be connected to the Video Gateway unit
and to their power supplies, as necessary.
A PC should be on the same LAN as the Video Gateway or connected to the unit by a LAN cross cable.
There are two ways that you can connect a PC to the same LAN as an MVG400 or UVG400:
Using the supplied Ethernet (network) cable, connect the network connector of the PC to one of the Ethernet
In connectors on the rear panel of the unit. The PC will then be included in the network managed by the
router. (It is preferable to use this method the first time you connect to the unit, before it has been configured.)
Using the supplied Ethernet (network) cable, connect the Ethernet Out connector on the rear panel of the unit
to a LAN connection point. Connect the PC to the same LAN through a different connection point.
NOTE: Do not connect a LAN connection point to one of the Ethernet In connectors; if you do, the system
will not function properly and will reset itself continuously.
Installing SVMultiClient
The simplest way to open the Video Gateway’s configuration utility is by using the SVMultiClient application on a
PC that is on the same LAN as the Video Gateway (see Before You Begin, page 6). Thus, before you begin
configuring the Video Gateway, you should install SVMultiClient on the computer that you will use for the
configuration tasks.
After the unit is configured, you can check the installation and configuration using the SVMultiClient you installed
on the PC (see Connecting to the Video Gateway, page 163). If this is successful, you can then install
SVMultiClient on a remote computer and connect to the Video Gateway via the internet.
NOTE: This chapter explains how to get started using SVMultiClient on a PC that is on the same LAN as the
Video Gateway so that you can configure the system and make sure it is working properly. For
complete information about connecting to SVMultiClient, locally or remotely, and using
SVMultiClient to view video, monitor events, and control devices, please refer to the SVMultiClient
User Guide.


To install the SVMultiClient application on the PC:
1. Download the latest version of the SVMultiClient installation program from the SerVision website
(http://www.servision.net). The installation file is called Setup-MultiClient-SV-x.x.x.x.exe (The
software version number appears in place of “x.x.x.x”.)
1. Double-click the installation file. The setup program starts.
Note: If a Microsoft Windows Security Warning dialog box is displayed, click Run.
2. Follow the on-screen instructions.
When the installation is completed, a SVMultiClient application icon is placed on your desktop.

Opening the Configuration Utility
This section explains how to work with the configuration utility –how to open it, access its main menu, and
navigate to the various configuration screens. The menu options and their settings are described in detail in the
following chapters.
When you first open the configuration utility, you should open it through SVMultiClient, as explained in this
section. This method of opening the configuration utility is recommended whenever SVMultiClient is on a PC that
is on the same network as the Video Gateway (or the PC and the Video Gateway are connected via a LAN cross
cable).
No internet connection is required to configure the Video Gateway. Once the network settings of the unit have been
configured in such a way that the unit can be accessed remotely via the internet, the configuration utility can also be
accessed remotely. For additional information, see Opening the Configuration Remotely, page 14.
NOTE: The configuration utility is compatible with Internet Explorer and Firefox.

7. Click Restart System. The unit restarts, and the changes are implemented. You are automatically logged out
of the configuration utility.
Note: Most changes to the settings in the configuration screens only take effect on the Video Gateway unit
after they are saved and the unit is restarted, as describe in steps 5–7. For additional information, see Saving
Configuration Changes, page 156.
Note: For security reasons, a configuration session times out after 15 minutes. If the configuration utility is
open with no user activity (pages loaded) for more than 15 minutes, you must perform the login procedure
again to continue configuring the Video Gateway unit. Configuration changes that were made during the
timed-out session are not discarded, as long as Update was clicked in the relevant screen before the time-out
occurred.
Opening the Configuration Remotely
Once the unit has been configured for remote client access via the internet (see LAN Settings, page 38), you can also
access the configuration utility remotely via the internet. To do this, all you need is a PC that is connected to the
internet. You can then access the configuration utility in one of the following ways:
Through SVMultiClient: Connect to the Video Gateway and use SVMultiClient to access the configuration
utility, as explained below. (For additional information about working with SVMultiClient, please refer to the
SVMultiClient User Guide.)
Manually through a browser: Enter the address and port in the Address field of a browser window, as
described under Opening the Configuration Manually, page 14.
Both of these methods can also be used to access the configuration utility over the internet through a proxy
connection.



To access the configuration utility remotely through SVMultiClient:
1. Connect to the Video Gateway through SVMultiClient.
Note: SVMultiClient's Search function does not work over the internet. Therefore, you will have to manually
add and configure the connection to the Video Gateway. For information about how to do this, please refer to
the SVMultiClient User Guide.
2. In the Connection Panel (left panel) of SVMultiClient, select the Video Gateway.
3. At the bottom of the Connection Panel, click the Config button. A new browser window opens, and
automatically connects to the configuration utility login page for the Video Gateway.
Note: If you cannot connect remotely through port 10000, the login page will not appear at this point, and the
browser will display an error message instead. Change the port number in the Address field of the browser
from 10000 to the port that is set in the router's port forwarding settings (see General System Settings,
page 17), and press Enter to reload the page. The login page should then appear. For additional information,
see Opening the Configuration Manually, below.
Note: If more than one SerVision Video Gateway is connected to the internet via the same router, each of
them must use a different port. When you click Config in SVMultiClient, the browser automatically connects
to port 10000. As a result, SVMultiClient may initially connect you to the wrong Video Gateway unit. In this
case, you should manually correct the port number in the Address field of the browser, as explained in the
previous note.
Opening the Configuration Manually
The configuration utility can be opened manually in a browser using the IP address and port of the unit. This is
particularly useful in situations in which you cannot open the configuration utility through SVMultiClient. This is
most likely to occur when you are opening the configuration utility remotely and either do not have access to
SVMultiClient or cannot connect to the unit remotely through port 10000.

SerVision Embedded Video Gateway System Guide
Getting Started 15
To open the configuration utility manually, you must know the network address (IP or hostname) of the Video
Gateway and the port allowing access to the configuration utility. The required network address depends on whether
you are accessing the configuration utility through a local connection (through the same LAN or through an
Ethernet cross cable) or a remote connection (through the internet):
Local connection: The network address is the private IP address of the Video Gateway on the local network.
This can either be its dynamic IP, or, if it has one, its static IP. The port is 10000.
Remote connection: The network address is the public IP or hostname of the router through which the Video
Gateway connects to the internet. The port is the port that allows access to the configuration utility via port
forwarding.
If you connect through a proxy connection, you must also know the network address and port of the proxy server.



To open the configuration utility manually:
1. Open a web browser.
2. In the Address field of the browser, enter the IP address and system port number of the Video Gateway, as
follows:
Connection

screen resolution is 704×480 pixels for NTSC systems and 704x576 pixels for PAL systems. Available
smaller screen sizes are CIF (one quarter of full screen; 352x240 pixels for NTSC systems and 352x288 pixels
for PAL systems) and QCIF (one sixteenth of full screen; 176x120 pixels for NTSC systems and 176x144 for
PAL systems).
VGA normally displays properly even on analog equipment such as CCTV screens. If your system supports both
resolutions, it is recommended that you select VGA resolution because it requires slightly less system resources.
Ignition-Off Shut-Down
The Ignition settings define whether the MVG or CVG-M unit should automatically shut down when the vehicle
ignition is turned off and, if so, how long the unit should continue operating after the ignition is turned off before it
shuts down.
Download Optimizations
Downloading recorded video uses system resources that would otherwise be available for other functions such as
recording or streaming live video. Download optimization settings are used to tweak the allocation of system
resources between downloading and other system processes.
These optimization settings are most important for mobile Video Gateways, which may be subject to vastly
different network conditions at different times. For example, if a bus is on the road, it typically only has access to a
cellular connection, which has very limited bandwidth, but when it is the bus yard, it probably also has access to a
high-speed WiFi network. In this case, downloading of the recorded video can be scheduled for times when the bus
is in the yards. Since recording video is only necessary when the bus is on the road, it is best to suspend recording
while downloading is being performed, because this speeds up the downloading process.
The following download-optimization options can be selected:
Enabled: Prevents the unit from initiating transmission of a new stream of recorded video to a client device,
and from beginning to download live or recorded video to a client device, when video is already being
downloaded from the unit. Live streams can be initiated, and all processes that are already in progress
(streaming of live or recorded video to a client or to a connected CCTV monitor, and downloading of video)
continue uninterrupted, unless one or more of the download-optimization options described below are
selected.
Stop Recording on Download: In addition to the above, stops all video recording on the unit when video is
being downloaded from the Video Gateway. This option increases the download speed, because it allocates
more of the unit’s resources to the download task. However, it also means that there may be gaps in the
recorded video at the times that the video is downloaded.

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 Defining Alternate Outlines, page 149.
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 SMS and E-mail Notifications, page 61.
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 Settings, page 119.
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.
