Overview

The S4200 series allows digital video transmission over license-free and licensed bands. It
delivers dual-stream video over local and wide area networks (LANs and WANs). Many
compression modes (also called codecs—coder/decoder) are available: a proprietary
MPEG-4-based mode called SM4, the MPEG-4 ISO 14496-2 comp liant mode, and MJPEG
(Motion JPEG). This wireless edge device is built on open standards to provide long-term
investment protection.

Combined with a Nextiva S4300 multipurpose outdoor wireless device or a commercial

802.11 access point, the S4200 series enables analog CCTV extension over the enterprise’s
network at a cost lower than that of laying new cables. The S4200 series also allows the
migration of analog CCTV cameras to an IP network.

Note: The S4200 series edge devices require professional installation.

The overview covers the following:

2

The second encoder of each input can be used for analytics or to encode video. The

second encoder gives better video encoding performances than the first one.
You can also purchase each device for the 4.9 GHz public safety band (the suffix -49 is

added to the product name, for example S4200-2V-49).
Unless otherwise specified, the word S4200 refers to any of these devices.
The S4200 offers the following additional key features:
 Integration of a multiband radio, video encoder, and antenna into small outdoor rated

enclosures, for convenient, discreet, secure, and reliable installation in real-world video
security applications

Security

Every S4200 device comes with the following security features:
 SSL —Every edge device comes with a unique SSL (Secure Sockets La yer) certificate for

securing its IP link. SSL is a commonly used protocol for managing the security of IP
message transmission. If enabled, the SSL protocol secures the VSIP communication
data. It does not apply to audio and video transmission.

 SPCF (SmartSight Point Coordination Function)—This proprietary MAC (Media Access

Control) protocol using AES encryption (with key rotation) over the wireless link to
secure communication between the devices and resolve “hidden node,” quality of
service, range, and problems inherent to 802.11 wireless networking products. SPCF
secures VSIP communication as well as audio, video, and serial data.

Frame Rate and Performance

The available video frame rates of each encoder of the transmitter are:

 NTSC—1 to 7, 10, 15, or 30 frames per second (fps)
 PAL—1 to 6, 8, 12, or 25 fps

Verint Video Intelligence Solutions 3

1: Overview

On the S4200, S4200-AS, and S4200-AS-2V devices, the composite signal of a video input
is sent to two separate encoders. You can customize each encoder to meet your system
needs, for instance in terms of frame rate and resolution. Here are typical scenarios
regarding encoder use:

Scenario Encoder 1 Encoder 2

point-to-point point-to-point unused

unused point-to-point

point-to-point and web interface web viewing at rate A point-to-point at rate B

web viewing and

unused

point-to-point at rate C

video management software view at rate D record at rate E

Note: You should not use the web interface and a video management software at the

same time to avoid configuration conflicts.

The video resolutions supported by the S4200 device are:

Resolution Number of Columns Number of Lines

NTSC/PAL NTSC PAL

QCIF 176 128 144
CIF 352 240 288

 Mexico—The use of the 4.9 GHz in Mexico is subject to a special approval from

COFETEL.

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
S4200 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.

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

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, see the “Compliance” appendix on page 136.

In the United States and Canada, five channels are available in the 5 GHz band, all

Wireless Cells

A wireless network is designed such that information can travel back and forth between two
points without the need for wires. For the S4200, this information consists of digitized
video, audio, and PTZ data sent to and from the wired network via an outdoor wireless
access point—either the Nextiva S4300 device or a commercial 802.11 access point.

A wireless cell consists of a group of wireless devices that communicate together on the
same frequency channel and that share the same wireless passkey. For example:

You can colocate many wireless cells if you respect certain conditions (see page 31).
Devices in a wireless cell can have two MAC (Media Access Control) roles, master or slave:
 A master device controls the access over the wireless medium. It takes care of channel

selection and slave authentication to provide access to the wireless network. Finally , the
master allocates bandwidth among all connected slaves.

 Slave devices need a master to access the wireless medium to transfer data, through a

polling mechanism. The S4200 devices are always slaves.

Nextiva S4200 Series User Guide

802.11 Support

The S4200 devices can use commercial 802.11-compliant access points in all frequency
bands (2.4 GHz, 4.9 GHz, and 5 GHz).

It is assumed that the network administrators wanting to add S4200 transmitters to their

802.11 wireless network are knowledgeable about this protocol. In the remaining of this
user guide, the access point will be a Nextiva S4300.

The S4200 in the 802.11 mode supports the following security mechanisms:

 No security—Not recommended
 WEP—Not recommended
 WPA and WPA2 (also known as 802.11i) in personal mode (PSK)
 WPA and WPA2 in Enterprise mode, with an 802.1X authentication server

Note: WPA and WPA2 are not available with the proprietary SPCF MAC mode.

 The S4200 will not be able to connect to an S4300.
 The inherent problems with 802.11 wireless network products, such as the “hidden

node” and quality of service issues, will be present. Furthermore, the ranges of the
equipment will be lower than with the SPCF protocol.

System Planning

When installing many wireless systems in the same area, you have to carefully plan their
positions in order to prevent radio interference and select the appropriate antennas.

The grouping of devices in each wireless cell is determined by their respective locations
with respect to one another and by the available outdoor wireless access points. As a rule of
thumb, there should be a clear RF line of sight between each S4200 device and the access
point in each cell. However, the S4200 devices can be completely hidden from one another.

Point-to-Multipoint Application

A point-to-multipoint application is a wireless cell made up of an S4300 access point (the
master) and several S4200 transmitters (the slaves). Here is a typical point-to-multipoint
system:

For example, to associate three S4200 devices to one access point, you need to:

1. Assign the same wireless passkey to the S4200 devices and the S4300 access point.
The wireless passkey must be different from that of other colocated cells, if any.

2. Assign a frequency channel to the S4300 device. The associated S4200 devices will
automatically use their master’s channel.

3. Install the S4200 devices such that each one has a clear RF line of sight with the S4300
access point.

For the configuration and installation procedure, see page 34.

Using IP Cameras with the S4200

The Ethernet port on the S4200 and the optional two-camera models provide new
configuration possibilities. Although video data from more than a single camera can be
transmitted from one S4200 transmitter, you must take several factors into account: the
total throughput available from the S4200, the available bandwidth for the wireless cell,
and the total amount of bandwidth used by each link in the cell.

If using a single S4200 for multiple camera transmission, it is important to remember that
the onboard processor has a finite amount of processing power available. F or instance, you
can achieve 4CIF resolution at 30 fps with a single analog camera connected to an S4200
transmitter; however, if an IP camera is connected to the Ethernet port of the S4200, some
processing power is required to transport the data stream of the IP camera from the
Ethernet port out to the radio for transmission to the S4300 access point.

The S4200 processor has the ability to forward an Ethernet stream equal to the maximum
available bandwidth on the wireless link. Obviously, using the maximum available
bandwidth only for the Ethernet port leaves no bandwidth for the video streams from the
encoders. Also, to attain good encoding performance for the analog cameras connected to
the S4200, the maximum amount of Ethernet traffic from the Ethernet port should not
exceed 2 Mbps; exceeding this value will seriously affect the performance of the encoders.
If maximum encoder performance is required (4CIF 30 fps), the total amount of Ethernet
traffic being sent from the S4200 should not exceed 4 Mbps.

For example, consider a wireless cell with four cameras using two S4200 transmitters. If
this system is designed such that the distances dictate a channel data rate of 12 Mbps, the
total amount of video bandwidth for the entire wireless cell will be 9.5 Mbps at distances of
less than 3.1 miles (5 km).

The SPCF MAC protocol divides this video bandwidth equally between the two transmitters,
therefore providing 4.75 Mbps for each pair of cameras in the wireless cell. This equates to
a total of 2.4 Mbps per camera, which can accommodate the following resolution and frame
rate (NTSC/PAL) combinations, with either two analog cameras or a combination of one
analog and one IP camera using MPEG-4 encoding:

 4CIF at 15/12 fps
 2CIF at 30/25 fps
 CIF at 30/25 fps

As the number of multicamera links increases, the video bandwidth available for each
camera reduces. With the previous example and four transmitters instead of two, the
bandwidth available for each camera is 1.2 Mbps (9.5 Mbps divided by four transmitters
divided by two cameras per transmitter).

If an IP camera is used with MJPEG compression, you must be careful in ensuring that the
combination of frame rates and resolutions from both the IP and analog cameras do not
exceed the maximum video bandwidth available.

As link distances increase, the total available video bandwidth will decrease due to free
space loss and other attenuating factors. If this is not taken into account in the design
phase, problems will surface which will have a detrimental effect on the total system
performance.

2: System and RF Planning

To help you plan your system, here are typical scenarios, where:
 The maximum number of analog cameras is connected on the device (one for the

S4200 and two for the S4200-2V).

 The compression mode is MPEG-4 or SM4.
 There is a single stream per camera.
 There is clear RF line of sight, with an RF margin of 15 dB or better to maintain the data

rate specified.

 The video performances supplied include a video resolution, a frame rate expressed in

frames per second (fps), and bit rate expressed in kilobits per second (kbps).

Compatibility Issues

When planning your wireless systems, you have to take into account the firmware versions
of the involved devices. It is recommended that the S4200 transmitters have the same
firmware versions as their associated S4300 master. Furthermore, you can use the S4200
with an S3100 access point at firmware version 4.12 or higher.

In a wireless cell, 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:

 Update the devices starting with the farthest (in terms of number of RF hops) from the

computer running the procedure.

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

Video Bit Rate and Data Throughput

You can theoretically connect up to 24 S4200 devices to a master access point in a wireless
cell. In practice however, video quality , frame r ate, and system lay out can limit the number
of devices that a single master access point can support.

Available video data throughput can be evaluated using the Wireless System Margin
Calculator that you can find on the Verint extranet. Available video data throughput
depends on the transmission (tx) bit rate used by each slave on the wireless network.

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 the frequency channel width: 20 MHz in all available bands, or 5 MHz and
10 MHz in the 4.9 GHz frequency band.

TPC

If the country of operation of the S4200 device requires conformity to the TPC (Transmit
Power Control) rules, the maximum EIRP (effective isotropic radiated power) is reduced by
3 dBm from the allowed maximum value; for example, if the maximum EIRP is 30 dBm in
the band and region of operation, the maximum EIRP in the device will be set to 27 dBm.

The combined transmission power of the device and its antenna must not exceed this
maximum value. For that reason, you must specify the antenna gain during configuration;
the device will automatically take it into account and adjust its own transmission power
accordingly at startup. This adjustment is done in all wireless devices (masters and slaves).

To meet local regulations, you must use only antennas that conform to the requirements
specified in the “Compliance” appendix on page 136.

DFS

In countries following the DFS (Dynamic Frequency Selection) regulations, frequency
channel selection is performed by the master S4300 device. Frequency channel selection
can be automatic (default) or manual; manual selection allows a better RF planning.

Note: DFS is required only in the 5 GHz band.

The radar detection mechanism (including channel availability check and non-occupancy
period) can be performed on all wireless devices (master and slave); it also allows for

RF planning and optimal wireless network performance.

regardless of the type of frequency channel selection.

Note: To minimize the false radar detection problem in colocated systems using adjacent

frequency channels, see page 29.

You should start the master first, then power the slave when the other device is in normal
operation.
