Overview
The S3100 is the latest addition to the SmartSight family of
outdoor, wireless, digital video bridging products. It covers the
2.4 GHz and 5 GHz frequency bands in North America and
Europe.
Note: The S3100 units require professional installation.
Verint Video Solutions 1
1: Overview
About the S3100
The S3100 license-free video bridge has many uses, including:
Point-to-multipoint application—One S3100 bridge and
multiple S1100w units
Point-to-point repeater—Two S3100 units acting as a range
extender for one or many pairs of S1100 units
Point-to-multipoint repeater—Two S3100 units acting as a
range extender for multiple S1100w units
Wireless bridge—Two S3100 units linking two networks
(wired or wireless)
To cover these application types, the following S3100 models
are available:
S3100-RP: A repeater device made up of two units
S3100: A single unit for the other applications
Unless otherwise specified, the word S3100 refers to any of
these units.
Every S3100 unit comes with the following security features:
SSL—Every unit is shipped with a unique SSL (secure
sockets layer) certificate for securing its IP link. SSL is a
commonly used protocol for managing the security of IP
message transmission. Therefore, the connections between
two units or between a unit and the SConfigurator tool can
be secured.
The SSL protocol secures the VSIP communication data. It
does not apply to audio and video transmission.
Once a unit is in secure mode, you cannot access it
anymore with Telnet and you cannot perform firmware
updates through the IP network on it. However, you can
configure it with SConfigurator.
For more information about this security feature, refer to
the SConfigurator User Manual.
SPCF/SDCF—These proprietary MAC (media access control)
protocols use AES encryption (with key rotation) over the
wireless link to secure communication between the units.
They secure VSIP communication as well as audio and
video data. For more information, see page 12.

System and RF
Planning
To allow optimal configuration, you must properly plan your
network, especially configuration layout and RF (radio
frequency). Planning is especially required if you want to
install many systems in the same area, in order to prevent
radio interference between the colocated units and to select
the appropriate antennas. In all cases, follow the recognized
RF installation practices.
Verint Video Solutions 5
2: System and RF Planning
Available Frequency Bands and Channels
The S3100 supports communications in the following frequency
bands, in North America and Europe:
2.4 GHz OFDM, also known as 802.11g
5 GHz OFDM, also known as 802.11a
2.4 GHz Band
The 2.4 GHz band provides 11 channels in North America and
13 in Europe. In these two regions, only channels 1, 6, and 11
are non-overlapping. All these channels are for indoor or
outdoor use. The center frequencies of the channels are:
Channel Frequency (GHz) Channel Frequency (GHz)
1 2.412 8 2.447
2 2.417 9 2.452
3 2.422 10 2.457
4 2.427 11 2.462
5 2.432 12 2.467 (Europe only)
6 2.437 13 2.472 (Europe only)
7 2.442
5 GHz Band
In the 5 GHz band, the number of available channels and
sub-bands vary depending on the country of operation.
Most European countries adhere to the DFS (dynamic frequency
selection) and TPC (transmit power control) regulations
established by the European Telecommunications Standards
Institute (ETSI); these regulations apply to the 5 GHz
frequency band only. To know which bands are available in your
country of operation and whether your country adheres to DFS
and TPC, refer to the Wireless Frequency Plan document
located on our web site (Tools & Demos section).
6 Verint Video Solutions
S3100 User Manual
In North America, nine channels are available in the 5 GHz
band, all non-overlapping and for indoor or outdoor use. The
center frequencies of these channels are:
Channel Frequency (GHz) Channel Frequency (GHz)
52 5.26 149 5.745
56 5.28 153 5.765
60 5.30 157 5.785
64 5.32 161 5.805
165 5.825
In Europe, the 11 non-overlapping channels, for indoor or
outdoor use, are:
Channel Frequency (GHz) Channel Frequency (GHz)
100 5.50 124 5.62
104 5.52 128 5.64

120 5.60
Wireless Cells
A wireless network is designed such that information can travel
back and forth between two points without the need for wires.
Wireless devices are grouped into wireless cells. The devices in
a cell communicate together on the same frequency channel
and share the same wireless passkey (described on page 49).
Verint Video Solutions 7
2: System and RF Planning
Roles
An S3100 can have two MAC (media access control) roles,
according to its function in the wireless cell: master or slave.
The other wireless units (S1100, S1100w) that are connected
to S3100 bridges are clients. Clients always connect to a
master S3100.
In this first example of a wireless cell, two S3100 units, a
master and a slave, form a wireless bridge:

The second example shows three wireless clients associated to
an S3100 master unit:

S3100 User Manual
Compatibility Issues
When planning your wireless systems, you have to take into
account the firmware versions of the involved units. It is
recommended that the S3100 units have the same firmware
versions as their associated slaves and clients. Use the
following matrix to ensure complete compatibility between your
units:
Slaves and clients
V2.55 V2.56 V2.60 V3.10 V3.20 V3.30
V2.55 yes yes no no no no
Master
S3100
In a wireless cell involving S1100w units, the order in which
you configure the units (either the first time or later when they
are installed in the field) or update their firmware is critical if
you do not want to lose access to them. You should then:
1. Update or configure the units starting with the farthest (in
2. One step at a time, get closer to the host computer.
In a point-to-point repeater, you should:
V2.56 yes yes no no no no
V2.60 no no yesyesyesyes
V3.20 no no yesyesyesyes
V3.30 no no yesyesyesyes
terms of number of RF hops) from the computer running
the upgrade procedure.
1. Update the firmware of all S1100 pairs, starting with the
remote unit.
2. Change the IP address of the computer running
SConfigurator (see page 40).
3. Update the firmware of the two S3100 units.
Verint Video Solutions 9
2: System and RF Planning
For example, consider the following wireless cell:
S1100w 1
S3100 3 S3100 2
S3100 1
S1100w 2
You should update or configure the units in the following order:
1. S1100w 1—You then lose contact with S1100w 1.
2. S1100w 2—You then lose contact with S1100w 2.
3. S3100 1—You can then reach all units.
4. S3100 2—You then lose contact will all units except master
S3100 3.
5. S3100 3—You can then reach all units.
For the complete firmware update procedure, refer to the
SConfigurator User Manual.
Video Bit Rate and Data Throughput
You can connect up to 16 client and 7 slave units to a master
bridge in a wireless cell. However, video quality, frame rate, and
system layout can limit the number of units that a single
master bridge can support.
Furthermore, video quality and frame rate influence the
required data throughput. Therefore, you need to carefully plan
the number of cameras that will work on a link. Data
throughput is influenced by the MAC protocol used; for more
information about the protocols, see page 12. The following
figures were measured in typical setup situations. They may
vary depending on your configuration.
10 Verint Video Solutions
S3100 User Manual
The total data throughput for the SPCF protocol in the 5 GHz
band, in a unidirectional UDP link setup, is:

cameras are connected, consult the Bit Rate Settings for Video
Servers document located on the Verint Video Solutions web
site (Tools & Demo section).
Verint Video Solutions 11
2: System and RF Planning
System Planning
The grouping of units in each wireless cell is determined by
their respective locations with respect to one another and by
the available outdoor wireless bridges. As a rule of thumb, each
client or slave unit must have a clear RF line of sight with its
master bridge within each cell. However, the client and slave
units can be completely hidden from one another. For more
information about the RF line of sight, see page 26.
MAC Protocols
Depending on the type of applications, an S3100 unit uses one
of the two proprietary MAC protocols that solve problems
inherent to 802.11 wireless networking products.
The SPCF (SmartSight point coordination function) protocol
resolves the “hidden node,” quality of service, range, and
security problems. SPCF is used in point-to-multipoint
applications and in repeater contexts. With this protocol, a
master S3100 has total control over the radio frequency used;
therefore, in an RF line-of-sight context, you cannot install two
cells sharing the same frequency channel.
You use the SDCF (SmartSight distributed coordination
function) protocol in point-to-point systems with a high volume
of video transmission, typically over long distances or when a
remote site is hard to reach. SDCF optimizes the RF link by
providing more data throughput. It also resolves the range and
security problems of the 802.11 standard. However, SDCF does
not manage the hidden node issue.
These two protocols are designed to work with SmartSight
units; they cannot work with wireless units from other vendors.
12 Verint Video Solutions
S3100 User Manual
Here is a typical context of use showing the two protocols. A
point-to-multipoint system is installed on every floor of a
multistorey parking building. The surveillance station is in
another building. The SDCF cell acts as a wireless bridge
between the two sites.

TPC
If the country of operation of the S3100 unit requires
conformity to the TPC (transmit power control) regulations, the
transmission power of its radio is automatically reduced by 3 dB
before leaving the Verint Video Solutions factory. However, in
case of a weak wireless link (that is, a link with an RF margin of
less than 15 dB), you have the opportunity to use the
maximum transmission power (see page 69).
DFS
To follow the DFS (dynamic frequency selection) regulations
specified by ETSI for the selected country, it is the master unit
that performs the tasks relative to frequency channel selection
and radar detection. In other words, you cannot choose the
frequency channel on which the unit will run.
Verint Video Solutions 13
2: System and RF Planning
The automatic selection of the frequency channel limits the
number and the configuration of the wireless cells.
Furthermore, when colocating many cells, all masters must
“see” each other.
Note: DFS is required only in the 5 GHz band.
You should start the master first, then power the client or slave
when the other unit is in normal operation.
A master unit in DFS mode goes through the following
sequence when booting up:
1
2
3
4
5
6
7
Unit initialization (3 seconds)
Starting order delay (0-15 minutes)
Frequency scan (10-20 seconds)
Radar detection (60 seconds)
Radar detected?
no
Normal operation
Radar detected?
no
yes
yes
1. The unit goes through the standard startup procedure.
2. The starting order delay ensures that colocated masters will
not select a frequency channel at the same time, therefore
minimizing the possibility that they choose the same one.
For more information about the starting order, see page 69.
14 Verint Video Solutions
S3100 User Manual
3. The unit scans the available frequencies (based on the
selected country) and automatically selects a channel. In
the selection process, channels already used by colocated
masters will be discarded at first.
4. The unit listens for 60 seconds on the selected channel to
detect possible radar interference.
5. If a radar is detected on the channel, the unit returns to the
scan process. Otherwise, it continues its bootup procedure.
6. The unit runs normally.
7. If a radar is detected, the unit immediately goes back to
the scan process to select another channel.
The boot sequence of client or slave units is:
Unit initialization (3 seconds)
1
Roaming (2-25 seconds)
2
Normal operation
3
1. The unit goes through the standard startup procedure.
2. The unit roams through the channels in the available
frequency bands to locate its master.
3. When the master is located, the client or slave unit runs
normally on the selected frequency channel.
Application Types
The S3100 units are used in many types of applications,
including:
Point-to-multipoint application—One S3100 bridge linking
multiple S1100w units to a LAN
Point-to-point repeater—Two S3100 units acting as a range
extender for one or many pairs of S1100 units

Point-to-Multipoint
A point-to-multipoint application is a wireless cell made up of
an S3100 bridge (the S3100 product code, called the master)
and several S1100w transmitters (the clients). The MAC
protocol for the master unit is SPCF. Here is a typical
point-to-multipoint system:
S1100w
To install a single wireless cell made up of three S1100w units
and one bridge, you have to:
1. Assign the same wireless passkey to the S1100w and
S3100 units.
2. In a non-DFS context, assign a frequency channel to the
S3100 unit. In a DFS context, the master unit will
automatically select a channel.
The associated S1100w units will automatically use their
master’s channel.

3. Install the S1100w units such that each one has a clear RF
line of sight with the S3100 bridge.
For the complete configuration and installation procedures, see
page 33.
Point-to-Multipoint Repeater
A point-to-multipoint repeater is used as a range extender for
wireless links, when you need a device to retransmit the signals
coming from S1100w units towards the Ethernet LAN. A typical
context is when you cannot obtain an RF line of sight between
the transmitters and the S3100 connected to the wired LAN.
