Overview

The S3100 series is a multipurpose, outdoor, wireless, digital video product covering the

2.4 GHz and 5 GHz frequency bands in North America and Europe, and the 4.9 GHz public safety band in North America.

Note: The S3100 series devices require professional installation.

Verint Video Intelligence Solutions 1

1: Overview

About the S3100 Series

The S3100 series has many uses, including:

 Access point application—A communication hub for multiple S1100w devices  Point-to-point repeater—A range extender for one or many pairs of S1100 devices  Point-to-multipoint repeater—A range extender for multiple S1100w devices  Wireless bridge—A link between two networks (wired or wireless)  Wireless bridge repeater—A range extender for a wireless bridge

To cover these application types, the following S3100 models are available:

 S3100—A single device for access point applications  S3100-BR—Two devices for wireless bridge applications  S3100-RP—Two devices for repeater applications

Unless otherwise specified, the word S3100 refers to any of these devices. Every S3100 device comes with the following security features:

 SSL —Every edge device 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 with another device or the SConfigurator tool can be secured.

If enabled, the SSL protocol secures the VSIP communication data. It does not apply to audio and video transmission.

Once a device 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 Guide.

 SPCF/SDCF—These proprietary MAC (Media Access Control) protocols use AES

encryption (with key rotation) over the wireless link to secure communication between the devices. They secure VSIP communication as well as audio and video data. For more information, see page 13.

System and RF Planning

To allow optimal configuration, you must properly plan your network, especially configuration layout and RF (radio frequency). Pla n ning is e specially r equired if y o u wan t to install many systems in the same area, in order to prevent radio interference between the colocated devices and to select the appropriate antennas. In all cases, follow the recognized RF installation practices.

Verint Video Intelligence 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  4.9 GHz OFDM, a public safety band available in North America only  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 independent (that is, 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

4.9 GHz Band

The 4.9 GHz band is a licensed band for entities providing public safety services focused on the protection of life, health, or property in North America. This band provides license holders with an interference-free, secure channel for robust and secure broadband technologies, including wireless video surveillance systems.

For more detailed information concerning the regulations governing licensing and use of frequencies in the 4.9 GHz band, see Subpart Y of the FCC document, Memorandum Opinion and Order and Third Report and Order at:

http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-03-99A1.pdf

The 4.9 GHz band has a width of 50 MHz (4940 to 4990 MHz). Since the standard channel width is 20 MHz, only two independent channels can co-exist in the band. However, the S3100 supports channel fragmentation, allowing narrower channels of 5 MHz and 10 MHz. You can have up to four independent channels with a 10 MHz width, and up to 10 with a 5 MHz width. All these channels are for indoor or outdoor use. For more information about channel fragmentation, see page 45.

6 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

The available channels are:

Channel Frequency (GHz) Channel width

3 4.9425 5 MHz 6 4.9475 5 MHz 7 4.9525 5 MHz or 10 MHz 7 4.950 20 MHz 8 4.9575 5 MHz 9 4.9625 5 MHz or 10 MHz 10 4.9675 5 MHz 11 4.9725 5 MHz or 10 MHz 11 4.970 20 MHz 12 4.9775 5 MHz 13 4.9825 5 MHz or 10 MHz 16 4.9875 5 MHz

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 the Verint Video Intelligence Solutions extranet (Technical Support, then Downloads, then Utilities and Tools).

In North America, five channels are available in the 5 GHz band, all independent and for indoor or outdoor use. The center frequencies of these channels are:

Channel Frequency (GHz)

149 5.745 153 5.765 157 5.785 161 5.805 165 5.825

In Europe, the 11 independent channels, for indoor or outdoor use, are:

Channel Frequency (GHz) Channel Frequency (GHz)

100 5.50 124 5.62 104 5.52 128 5.64 108 5.54 132 5.66 112 5.56 136 5.68 116 5.58 140 5.70 120 5.60

2: System and RF Planning

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 46).

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 devices (S1100, S1100w) that are connected to S3100 devices are clients. Clients always connect to a master S3100.

In this first example of a wireless cell, two S3100 devices, a master and a slave, form a wireless bridge:

Slave

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

S3100

Wireless clients

You can colocate many wireless cells if you respect certain conditions (see page 20).

Master

Compatibility Issues

When planning your wireless systems, you need to take into account the firmware versions of the involved devices. It is recommended that the S3100 devices ha ve the same firmware versions as their associated slaves and clients; however, from version 2.60 and up, the devices are fully compatible (for example, an S3100 at version 3.20 with an S1100w at version 3.60).

8 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

In a wireless cell involving S1100w transmitters, the order in which you configure the devices (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 devices starting with the farthest (in terms of number of RF hops) from the computer running the upgrade procedure.

2. One step at a time, get closer to the host computer.

In a point-to-point repeater, you should:

1. Update the firmware of all S1100 pairs, starting with the remote device.

2. Change the IP address of the computer running SConfigurator (see page 37).

3. Update the firmware of the two S3100 devices.

For example, consider the following wireless cell:

S1100w 1

S3100 3 S3100 2

S3100 1

S1100w 2

You should update or configure the devices 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 devices.

4. S3100 2—You then lose contact will all devices except master S3100 3.

5. S3100 3—You can then reach all devices.

For the complete firmware update procedure, refer to the SConfigurator User Guide.

Video Bit Rate and Data Throughput

You can connect up to 16 client and 7 slave devices to a master S3100 in a wireless cell. However, video quality, frame rate, and system layout can limit the number of devices that a single master device can support.

Verint Video Intelligence Solutions 9

2: System and RF Planning

Each time multiple client or slave devices are connected to a master S3100, the available bandwidth is divided equally between the connections. In the following example, two S1100w clients and one slave S3100 connected to a master on a 6 Mbps link each have 2 Mbps throughput.

S3100S3100

S3100

Note: In that context, you must ensure that all devices connected to a slave S3100 do not

require more than the available bandwidth. Otherwise video packets may be lost.

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.

The following figures were measured in typical setup situations. They may vary depending on your configuration. The total data throughput in a unidirectional UDP link setup varies depending on two factors:

 The MAC protocol. For more information about SPCF and SDCF, see page 13.  The frequency channel width: 20 MHz in all available bands, or 5 MHz and 10 MHz in

the 4.9 GHz frequency band.

The S3100 automatically adjusts the transmission speed with the current RF conditions. For the bit rate requirements of the edge devices to which the cameras are connected,

consult the Bit Rate Settings for Video Servers document located on the Verint Video Intelligence Solutions extranet (Technical Support, then Downloads, then Utilities and Tools).

System Planning

The grouping of devices in each wireless cell is determined by their respective locations with respect to one another and by the available S3100 devices. As a rule of thumb, each client or slave device must have a clear RF line of sight with its master device within each cell. However, the client and slave devices can be completely hidden from one another. For more information about the RF line of sight, see page 25.

MAC Protocols

Depending on the type of applications, an S3100 device 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 access point 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 ov er long distances or when a remote site is hard to reach—and in wireless bridge applications. 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 Nextiva devices; they cannot work with wireless devices from other vendors.

Here is a typical context of use showing the two protocols. A access point 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 device 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 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 63).

DFS

To follow the DFS (Dynamic Frequency Selection) regulations specified by ETSI for the selected country, it is the master device that performs the tasks relative to frequency channel selection and radar detection. In other words, you cannot choose the frequency channel on which the edge device will run.

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 device is in normal operation.

2: System and RF Planning

A master device in DFS mode goes through the following sequence when booting up:

Unit initialization (3 seconds)

Starting order delay (0-15 minutes)

Frequency scan (10-20 seconds)

Radar detection (60 seconds)

Radar detected?

Normal operation

Radar detected?

yes

1. The device 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 64.

3. The device 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 device listens for 60 seconds on the selected channel to detect possible radar interference.

5. If a radar is detected on the channel, the device returns to the scan process. Otherwise, it continues its bootup procedure.

6. The device runs normally.

7. If a radar is detected, the device immediately goes back to the scan process to select

another channel.

The boot sequence of client or slave devices is:

Unit initialization (3 seconds)

Roaming (2-25 seconds)

Normal operation

1. The device goes through the standard startup procedure.

2. The device roams through the channels in the available frequency bands to locate its

master.

3. When the master is located, the client or slave device runs normally on the selected frequency channel.

Application Types

The S3100 devices are used in many types of applications, including:  Access point—One S3100 device linking multiple S1100w transmitters to a LAN (the

S3100 model)

 Point-to-point repeater— Two S3100 devices acting as a range extender for one or many

pairs of S1100 transmitters (the S3100-RP model)

 Point-to-multipoint repeater—Two S3100 devices acting as a range extender for

multiple S1100w transmitters (the S3100-RP model)

 Wireless bridge—Two S3100 devices linking two networks, wired or wireless (the

S3100-BR model)

 Wireless bridge repeater—Two S3100 devices acting as a range extender for a wireless

bridge (the S3100-RP model)

Access Point

An access point application is a wireless cell made up of an S3100 device (the S3100 product code, called the master) and several S1100w transmitters (the clients). The MAC protocol for the master device is SPCF. Here is a typical access point system:

S1100w

S3100

2: System and RF Planning

To install a single wireless cell made up of three S1100w transmitters and one S3100, you need to:

1. Assign the same wireless passkey to the S1100w and S3100 devices.

2. In a non-DFS context, assign a frequency channel to the S3100. In a DFS context, the

master device will automatically select a channel. The associated S1100w transmitters will automatically use their master’s channel.

3. Install the S1100w transmitters such that each one has a clear RF line of sight with the S3100 device.

For the complete configuration and installation procedures, see page 31.

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 transmitters 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.

A point-to-multipoint repeater (the S3100-RP product code) is made up of two S3100 devices separated into two colocated cells. For example:

Master

Slave

Video management software

S3100 S3100S3100

Receivers

Repeater

To operate the two cells forming the repeater, you need to:

1. In each cell, assign the same wireless passkey to all the devices. The wireless passkey must be different from that of the other cell.

2. Always connect the S1100w transmitters to a master S3100, never to a slave.

3. Set the MAC mode of the S3100 in Cell1 to SPCF.

4. Set the MAC mode of the two S3100 devices in Cell2 to SDCF.

5. In a non-DFS context, assign a frequency channel to the master S3100 device in each

cell. For better isolation, use different frequency bands.

6. In a DFS context, set a different starting order for each master S3100. Ensure that the two masters see each other.

7. Install the S1100w and slave S3100 devices such that each one has a clear RF line of sight with its associated master.

For the complete configuration and installation procedures, see page 32.

Wireless Bridge

You use two S3100 devices (the S3100-BR product code)—a master and a slave—to transfer video surveillance data between two LANs when a wired connection is not av ailable or too costly to install. For instance, a wireless bridge application can connect remote S1900e-AS edge devices (the following illustration) or wireless devices without an RF line of sight.

Transmitters Receivers

S3100

Slave Master

To create a wireless bridge application, you need to:

1. Assign the same wireless passkey to the two S3100 devices.

2. In a non-DFS context, assign a frequency channel to the master S3100 device.

3. Set the MAC mode of the two S3100 devices to SDCF.

Video management software

4. Install the S3100 devices such that there is a clear RF line of sight between the two antennas.

You can also use the S3100-BR product in point-to-multipoint wireless bridges, to transmit video coming from IP cameras:

S3100

Slaves Master

All slaves (you can install up to seven of them) must be S3100-BR devices. The configuration of such an application is very similar to that of a standard wireless bridge, except that the MAC role of the devices is SPCF instead of SDCF.

For the complete configuration and installation procedures, see page 33.
