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:

the first video input of the devices. For details, refer to your Verint representative.
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
2CIF 704 240 288

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

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
independent and for indoor or outdoor use. The center frequencies of these channels are:

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

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

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.
The throughput for a 20 MHz channel is:

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.

The boot sequence of slave devices is:

2. The device roams through the channels in the available frequency bands to locate its
master; it does not transmit any data.
3. When the master is located, the slave runs normally on the selected frequency channel.
4. If the slave detects a radar on the channel during normal operation, it informs the
master then stops operation. Upon reception of this message, the master starts its
radar detection process.
Radar detection on slave devices can be disabled; for more information, see page 29.
Colocated Cells
You can operate many wireless cells in the same location, provided you follow guidelines
relative to frequency channel, wireless passkey, and distance.
The wireless passkeys of colocated cells must be different from one another, regardless of
their frequency channels.
Distance Limitations
The distance limitations between devices in colocated cells are:
The minimum distance between two devices is 3 feet (1 meter), regardless of the band
or channel used.
To avoid material damages, you must never power any two devices while their
antennas are facing one another with a distance of less than 10 feet (3 meters).
To reduce radio interference, separate as much as possible devices sharing the same
pole or installed on the same roof, even if they do not use adjacent channels.
If using adjacent channels, see page 120 for the recommendations on the minimum
distances to respect.

half the frequency channels are available, therefore ensuring that no adjacent channels
are used; however, you can make all channels available (for more information, see

It is suggested to limit the number of colocated cells to six in the 5.40–5.725 GHz band. By
respecting the following steps, you can assume that the cells will not share the same
frequency channel, making the complete bandwidth available for each one:
1. Assign a different wireless passkey to each cell.
2. Ensure that all masters “see” one another. For more information, refer to the “RF
Contact between Masters” appendix in the Nextiva S4300 Series User Guide.
This step is mandatory if automatic frequency channel selection is selected, and
strongly suggested for manual selection.
3. Position the devices so that there is at least 3 feet (1 meter) between each antenna.
4. If automatic channel selection is used, set a different starting order in each master
device: 1 for the first device, 2 for the device next to it, 3 for the third one, and so on.
Installing more than six cells in the 5.40–5.725 GHz band requires the use of adjacent
channels. This situation demands greater distances between the antennas to reduce
potential radio interference and false radar detection. Therefore, you should contact the
customer service team for assistance.

False Radar Detection
The design of wireless systems in a DFS context becomes difficult because not only can the
master devices cause an interference, but the slaves on an adjacent channel can also
generate interferences that can cause false radar detection. Therefore, to reduce the
possibility of false radar detection, it is strongly suggested to:
Limit the number of colocated cells to six.
Decrease the tx power of the wireless links that have a good RF margin (15 dB or
more). This way, the interference generated by the device is reduced.
Separate as much as possible devices sharing the same pole or installed on the same
roof.
In a context of adjacent channels, ensure that the signal level of a potentially
interfering device on the first adjacent channel does not exceed -50 dB, -36 dB on the
second channel, and -32 dB on the third channel. For example, if you use channel 100,
104 is the first adjacent channel, 108 the second channel, and 112 the third channel.
Manually select a frequency channel, to reduce the use of adjacent channels.
In addition, the following features help reduce the possibility of false detection events:
Half channel selection—This feature eliminates the possibility of using adjacent
channels. Enable this feature on all masters in a new installation to avoid the potential
conflict of having two masters on adjacent channels; in the web interface, the
parameter is called DFS/TPC Adjacent Channel Removal. By default this feature is
enabled.
If this feature is enabled, the channel list becomes:
100(DFS), 108(DFS), 116(DFS), 124(DFS), 132(DFS), 140(DFS), 254(Auto DFS/TPC)
The full channel list is:
100(DFS), 104(DFS), 108(DFS), 112(DFS), 116(DFS), 120(DFS), 124(DFS), 128(DFS),
132(DFS), 136(DFS), 140(DFS), 254(Auto DFS/TPC)
Slave radar detection management— This feature allows you to disable radar detection
on slave devices; in the web interface, the parameter is called Enable Radar Detection
on Slave. In a typical DFS environment, the slave can detect a radar and alert its
master to change the frequency channel. This situation can cause a major problem
because it increases the number of nodes that can detect false radar events caused by
adjacent channel interferences.
The default value is Disabled, meaning that the slave does not detect radars; in this
case, the slave EIRP is reduced from 30 to 23 dBm and the Tx power is automatically
reduced to meet the new maximum EIRP requirement.

Preferred Setups
In the 5.40–5.725 GHz band, the following colocated systems are the only ones supported
when automatic frequency channel selection is enabled, since the master devices must see
each other. In the manual channel selection mode, safe setups are:
T wo access point applications, in which the transmitters from one system do not see the
transmitters from the other cell. Both master devices see each other.
A point-to-multipoint repeater. Both master devices see each other.

Risky Setup
In the 5 GHz band in Europe, the following colocated system is not supported if the
automatic frequency channel selection is enabled, or is risky with manual selection mode if
a radar is detected:
Access point applications with hidden masters. In this context, the two S4300 masters
do not see each other, while transmitters 2 and 3 do.
RF Planning
Successful operation of a wireless link depends on proper RF path planning and antenna
installation. You have to install the devices in such a way that there is a clear RF line of
sight between the two antennas. The factors to take into account are:
Location evaluation
Antenna requirements
RF exposure
Location Evaluation
The path between the two antennas must be free of obstacles that could disturb
propagation. For very short link distances—less than 500 feet (152 meters)—you may be
able to establish a working link despite partial path obstruction. However, radio waves will
be in part absorbed and in part diffracted by the obstacles, therefore affecting link
reliability. Because the reliability of such an installation is highly unpredictable, Verint does
not recommend it. A path free of any obstacle is called an RF line-of-sight path.
T o establish an RF line-of -sight path, you must take into account the sph erical nature of the
radio signal transmitted between the two antennas. This spherical signal spreads out from
both ends of the communication path and creates a three dimensional elliptical area
immediately surrounding the visual line of sight. This elliptical area varies in width
depending on the length of the line of sight; the longer the length, the thicker the elliptical
area becomes.
Verint Video Intelligence Solutions 31
2: System and RF Planning
Visual line of sight First Fresnel zone (F1)
The region outlined by this elliptical area is known as the first Fresnel zone. The Fresnel
zone is always thicker at the mid-point between the two antennas. Therefore what appears
to be a perfect line-of-sight path between the base and a remote station may not be
adequate for a radio signal; this is the difference between "visual" and "RF" line of sight.
In practice, it has been determined that a radio path can be considered an RF line-of-sight
path if it has a clear opening through 60% of the first Fresnel zone (or 0.6 F1). Here are
values for 0.6 F1 for various signal path distances and frequency bands:
Distance Values for 60% of the First Fresnel Zone Earth
Curvature
2.45 GHz 4.9 GHz 5.3 GHz 5.8 GHz
Effect
mile km ft m ft m ft m ft m ft m
1 1.6 14 4.2 9.8 3.0 9.5 2.9 8.9 2.7 0 0
4 6.5 27 8.4 19.5 5.9 18.7 5.7 18 5.5 2 0.6
7 11.3 37 11 25.8 7.9 25 7.6 23.6 7.2 6 1.8
15 24 53 16 37.8 11.5 36.4 11.1 35 10.6 29 8.8
For distances under 7 miles, the earth curvature effect is negligible. However, for greater
distances, you need to consider it in your calculations; for instance, for a 15-mile link in the
2.4 GHz band, the two antennas must be located 82 feet higher than the highest obstacle
in the RF line of sight between them (that is, 53 feet for the Fresnel zone plus 29 feet for
the earth curvature effect). Consult the customer service team for assistance.
A common problem encountered in the field and related to the 0.6 F1 clearance rule is
building obstruction. The proposed visual path may just barely clear a building but the RF
line of sight will not. In such a case, the signal will be partially absorbed and diffracted.
Increasing the height of the two antennas or the gain of the antennas are the only
alternatives to improve the link quality.
Note: At 2.4, 4.9, and 5 GHz, radio waves are highly attenuated by dense foliage. A link
established in the fall or winter season may be adversely affected in the spring and
summertime, if it is established below tree level.

Nextiva S4200 Series User Guide
Antenna Requirements
Verint offers many antennas to meet various distance requirements. You need to consider
many factors when choosing an antenna, including the distance to cover, the RF bit rate,
the radiated power (EIRP), and the frequency band. For systems located in North America
on the 5 GHz band, you can use the Wireless System Margin Calculator located on the
Verint Video Intelligence Solutions extranet (under Tools).
You must use only antennas certified by Verint. They meet the local regulations regarding
the maximum antenna gain allowed. The certified antennas are listed in the “Compliance”
appendix on page 136.
To ensure that the device meets the maximum EIRP in the region of operation, enter the
antenna gain in the device (in the SConfigurator Wireless pane or the Wireless
Communication page of the web interface); the device will automatically take it into
account and adjust its own transmission power accordingly at startup.
For fixed point-to-point applications in the 5.725 GHz–5.850 GHz in USA and Canada,
19 dBi and 23 dBi antennas can be used without transmission power reduction. It is the
responsibility of the installer to ensure that the system is used exclusively for fixed
point-to-point operation.
Note: Connecting an antenna with a gain higher than the value for which the device is
certified for the frequency band and region of operation is prohibited. It is your
responsibility to ensure that you respect the regulations in place.
Antenna installation must be performed by certified professionals.
RF Exposure Considerations
In order to comply with the RF exposure requirements of CFR 47 part 15 in North America,
the devices must be installed in such a way as to allow a minimum separation distance of
12 inches (30 cm) between antennas and persons nearby.
Other countries may have different regulations. Please consult with local regulations prior
to installation.

Performing a Point-to-Point Connection
A point-to-point connection is the association of a transmitter and a receiver to view video
coming from an analog camera on an analog monitor. The Nextiva receivers are the
S1970e-R and S1504e-R. You can connect each of these receivers to up to four
transmitters, to create a maximum of four different point-to-point connections. Here is a
single connection:
You can also use a point-to-point connection to transfer audio, input/output, or serial port
data, if the transmitter and receiver have these features.
Typically, both devices sit on the same IP subnet as SConfigurator and have the same VSIP
port; to access other devices, refer to the device discovery section in the Verint
SConfigurator User Guide.
To associate a transmitter and a receiver in a point-to-point connection:
1. Start SConfigurator.
2. In the Units tab, discover the desired devices. The discovered devices appear in the
Units box.
3. Select the Connections tab, then click Add. The Connection Creator window appears.
42 Verint Video Intelligence Solutions
Nextiva S4200 Series User Guide
4. Select a transmitter in the left column and a receiver in the right one.
In the Transmitters column, you have access to the two encoders of each input; the
video stream is the same for both. Encoder1 is always reserved for viewing live video
with the web interface, therefore you should use Encoder2 for point-to-point
connections; however, you can use the same encoder for both functions if you want the
same resolution and frame rate.
5. In the Video list, select the desired transmission mode for video data. The available
values are:
RTP/UDP—A video mode using RTP (Real Time Transport Protocol, RFC 3550) over
UDP. It is the preferred mode for LAN environments; however, it does not guarantee
proper reception of packets. (default)
VSIP/UDP—A legacy mode, using the proprietary VSIP video protocol over UDP. The
preferred UDP mode is RTP/UDP.
RTP/TCP—A video mode using RTP (Real Time Transport Protocol, RFC 3550) over
TCP. It can be useful over WANs, Internet, or LANs needing more robust or secure
connections. This mode guarantees proper reception of packets, but could slow
down the effective frame rate to a level which is not acceptable.
VSIP/TCP—A legacy mode, using the proprietary VSIP video protocol over TCP. The
preferred TCP mode is RTP/TCP.
6. If you are not transferring I/O data (typically alarms) between the two selected
devices, clear Forward I/O.
7. If you are not transferring serial port data (like PTZ commands), clear Forward Serial
Port Data.
Tip: The serial connection is automatically performed with the TCP protocol, which
may induce lag time on a slow wireless connection. If it is the case, change the
protocol to UDP. For the procedure, see page 105.
8. To enable audio between the devices, ensure that Enable Audio is checked, then select
the audio mode. The available modes are:
Full Duplex—Audio data is transferred in both directions simultaneously.
PTT/PTL—Push-to-talk/push-to-listen is a half-duplex mode that allows you to
control audio communication by using a button to switch from voice reception to
transmission mode. Audio data will be transmitted only if the PTT or PTL buttons
are pressed.
Note: On a receiver, you can activate audio on a single connection only. The active
audio connection is the last that was performed.
The audio connection will remain the same even if the S1970e-R is in guard tour
mode, that is, the receiver will not switch between the audio streams of its four
connected transmitters. For more information, refer to the Nextiva S1900e
Series User Guide.
9. Click Connect.
10. In the SConfigurator confirmation window, click OK.

on the device and to run it down the pole. Tie the cable to the pole 2 feet (0.7 meter)
or less below the device, while ensuring that there is no tension between the device
and the tie point. Insert the other end of the cable in a waterproof electrical box for
outdoor applications. Add external surge protection near the device to protect the
Ethernet port.
For more information about surge protection, see Appendix C on page 110.
Tip: If the S4200 is directly exposed to the sun in an environment likely to reach 122°F
(50°C), install a sun shield. Otherwise, reduce the maximum operating temperature
by 18°F (10°C) to protect the equipment; that is, without a sun shield, the maximum
temperature should be 104°F (40°C).

15. To properly fuse the power supplied to the wireless device, install a fuse between the
power source and the power cable. The fuse must have the following ratings: UL Listed,
250V, 2.5A, Fast-Acting.
16. Power up the S4200 device (see page 37).
Note: Power supplies other than the approved ones (PS2440) require verification of
operation with the S4200 before use.
If you are using a power supply other than the one supplied by V erint, y ou need
to ensure that it has a minimum capacity of 1.6A (for 12V DC) or 25 VA (for
24V AC).
17. To improve the signal level between the devices, use the antenna alignment utility from
SConfigurator.
Installing an External Antenna
If you bought a high gain antenna, install it after the S4200 is in place.
Note: You can only use antennas certified by Verint. For the list, see the “Compliance”
appendix on page 136.
The antenna requires professional installation.
The installer must enter the proper antenna gain in the device so that the
transmission power is automatically adjusted. It is the responsibility of the installer
to ensure that the proper antenna gain is configured. For fixed point-to-point
applications in the 5.725 GHz–5.850 GHz in USA and Canada, 19 dBi and 23 dBi
antennas can be used without transmission power reduction. It is the responsibility
of the installer to ensure that the system is used exclusively for fixed point-to-point
operation.
An omni-directional antenna (ANT-WP8-49/5x product code) is available for installation on
a master device that requires a 360º coverage. Use it if the following conditions are met:
There is a short distance between the master and slave devices (less than
0.6 mile/1 km). A typical use is in parking lots.
At least three slaves are connected to the master.
The antennas of the slaves point towards the omni-directional antenna and are in its
vertical coverage zone (vertical beamwidth of 14º).
The omni-directional antenna is installed vertically, without any tilt.
To install an external antenna:
1. Install the antenna above the S4200 device. If you bought your antenna from Verint,
use the supplied pole mount bracket.
2. Remove the cap from the antenna connector on the S4200.
Verint Video Intelligence Solutions 49
3: Configuring and Installing the Device
3. Screw the SMA connector of the antenna cable to the antenna connector on the S4200
and tighten it with a 0.25-inch (0.6 centimeter) wrench.
Warning: Do not over-tighten to avoid damaging the connector. The recommended
torque is 8 lbf-inch (100 N-cm). You could use a calibrated SMA torque
wrench (for instance, from the Pasternack company, available at
www.pasternack.com).
Never leave the antenna connector without either the cap or the SMA
connector. The antenna connector must be terminated to avoid damaging the
device radio.
4. Apply two or three layers of electrical tape around all RF connections.
The antenna cable and connectors are weather-tight; however, vibration caused by the
wind will over time loosen the connectors and reduce the efficiency of the gaskets. The
electrical tape will prevent this situation.
5. With SConfigurator , enter the new antenna gain and change the antenna selection from
Integrated to External (see page 40).
6. Carefully align the antennas of the S4200 and access point so that they have a clear RF
line of sight.
7. To improve the signal level between both devices, use the antenna alignment utility
from SConfigurator.
Connecting the RS-422/485 Serial Port
The Nextiva edge devices support only the RS-422 and RS-485 asynchronous protocols. For
any other protoco l, you may need a converter.
On an S4200-2V transmitter, you can transmit serial data to two PTZ cameras if the
protocol is RS-485. The corresponding PTZ keyboard must be able to reference each
camera individually. In this context, perform the serial connections on both cables.
RS-422 allows you to have one PTZ camera and one fixed camera.
Use the video/serial/power cable to properly connect the device to a serial peripheral. Here
is the wiring scheme for the four-wire RS-422 or RS-485 protocol:

Configuring the I/Os
You can progr am alarms (or events) or use the audio features of devices with a single video
input, using the supplied alarm/audio cable (CABAA).
The S4200 supports two alarm inputs, one alarm output, one audio input, and one audio
output. Each signal has a dedicated purpose:
Signal Color Purpose
Alarm Input 1 yellow/black An alarm link in a point-to-point configuration or with a
video management software
Alarm Input 2 white/black Push-to-talk (PTT) audio transmission mode
Alarm Output red/black Relay for the input 1 signal in point-to-point alarm mode
Audio Input green/black Connection to the line-out plug of a pre-amplifier
Audio Output blue/black Connection to a speaker
You cannot program PTT audio and alarms at the same time, since alarm input 1 is used in
both contexts.
Since the S4200 transmitters are mostly used with a video management software, you will
perform most configuration and activation steps in it. Otherwise, in a point-to-point
connection, use SConfigurator for setup.
Alarms
The S4200 device can generate and receive alarms. Typically, an alarm is generated on a
transmitter and acknowledged on a receiver (for instance, an S1970e-R). To generate an
alarm on an S4200 transmitter, you have to short the alarm input 1 and alarm ground pins.
The output relay on the receiver is configured to close the contact between the two alarm
output pins (up to 48V at 100 mA) upon alarm activation. For example, with an S1970e-R
receiver:

With SConfigurator, you activate the alarm process by checking the Forward I/O box in the
Connection Creator window.
Audio
Two transmission modes for audio data are available, provided audio is supported
everywhere in your system:
Full duplex—Data is transferred in both directions simultaneously. The I/Os are
available for alarms.
PTT—The push-to-talk mode is a half-duplex mode that allows you to control audio
communication between two devices by using a button to transmit.
When creating a point-to-point connection between an S4200 transmitter and an S1970e-R
receiver in SConfigurator, you set the transmission mode in the Connection Creator window.
To activate the audio transmission channel, you must trigger an activation switch (for
example, a button) that is based on the short ing of the al arm input 2 and alarm ground
pins. If the PTT switches of both the transmitter and receiver are activated at the same
time, the receiver will have precedence: Audio will be transferred from the receiver to the
transmitter.
Here is a typical PTT application in a point-to-point context:
The S4200 device supports the line-in input type. With SConfigurator, ensure that the input
type in the Audio tab reflects this value.
Regardless of the transmission mode, the connections for the audio equipment are:
You plug the audio input signal of the device to the Line-out connector on a
pre-amplifier. Then you plug a microphone on the pre-amplifier.
You plug the audio output signal of the device to the Line-in connector on an amplifier.
Then you plug a speaker on the amplifier.

Configuring Wireless Communication
The wireless communication parameters are relative to radio frequency (RF) and wireless
security . The parameters vary depending on the MAC mode (SPCF or 802.11). It is assumed
that the network administrators wanting to add S4200 transmitters to their 802.11 wireless
network are knowledgeable about this protocol; for more information on 802.11, see
page 17.
For each MAC mode, there are two sets of parameters: basic and advanced.
Basic Wireless
The S4200 contains standard wireless parameters for the SPCF and 802.11 MAC modes.
66 Verint Video Intelligence Solutions
Nextiva S4200 Series User Guide
To configure the basic wireless parameters for SPCF:
1. In the navigation pane, expand Configuration, then click Wireless Communication.
The basic wireless communication parameters appear.
2. In the MAC Mode list, select SPCF. The available media access control values are:
IEEE 802.11—The standard protocol for using commercial 802.11-compliant access
points.
SPCF—The proprietary protocol that uses 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.
SDCF—The legacy proprietary protocol not used anymore. It used AES encryption
and resolved the range and security problems of the 802.11 standard, but did not
manage the hidden node issue.
Note: A change to the MAC mode is automatically applied because it has an immediate
impact on other parameters.
3. In the Passkey box, enter a unique user-supplied, case-sensitive identifier enabling
secure and encrypted RF communication in the wireless cell. The passkey must have
exactly 16 characters or 32 hexadecimal digits.
For the wireless connection to be secure, do no enter a known name (like a street
name), but instead use a mix of digits and letters. Do not disclose the passkey. The
connection security is based on the secrecy and uniqueness of the passkey. It is good
practice to change the default passkey during the configuration process.
Verint Video Intelligence Solutions 67
4: Using the Web Interface
4. In the MAC Role list, select the function of the device in the wireless system. The
required value for an S4200 is Slave. The available values are:
Master—A device that controls the access over the wireless medium. It takes care
of channel selection and slave authentication to provide access to the wireless
medium. The master also allocates bandwidth for all connected slaves.
Slave—A device that needs a master to access the wireless medium to transfer
data. A slave can also bridge data.
Note: A change to the MAC role is automatically applied because it has an immediate
impact on other parameters. However, this change will take effect in the device
only after you save the parameter and reboot the S4200.
5. In the RF Band list, select the radio frequency band used by the device. The available
values are:
802.11a (5 GHz OFDM)
802.11g (2.4 GHz OFDM)
Public Safety (4.9 GHz OFD M)
Note: A change to the RF band is automatically applied because it has an immediate
impact on other parameters. However, this change will take effect in the device
only after you save the parameter and reboot the S4200.
6. In the Channel list, select the frequency channel, within the selected band, that the
wireless system will use. It is the master device of the S4200 that selects the channel.
However, you can specify an initial value for the roaming process by which the S4200
will find its access point; be aware that this initial channel may not be the one used by
the access point.
In a 4.9 GHz band context, the list of channels varies depending on the chosen
bandwidth.
7. In the Channel Bandwidth list, select the width of the frequency channel when the
4.9 GHz public safety band is selected. This parameter only appears for the 4.9 GHz RF
band. The values can be 5 MHz, 10 MHz, and 20 MHz (default).
Note: A change to the channel bandwidth is automatically applied because it has an
immediate impact on other parameters. However, this change will take effect in
the device only after you save the parameter and reboot the S4200.
8. In the Tx Bit Rate list, select the data rate at which the device operates. A high bit rate
reduces the effective distance between two functional devices. You can set the bit rate
in slave devices only.
When a slave connects to its master for the first time, it automatically receives the best
possible value (the Auto value), with a default RF margin set to 15 dB (to change the
margin, see page 75).
68 Verint Video Intelligence Solutions
Nextiva S4200 Series User Guide
Once the device is operating properly, Verint strongly recommends to change the
configured bit rate from Auto to the actual bit rate of the connection. This way, the
wireless communication will be more stable in the presence of changing atmospheric
conditions or other RF interferers. To know the actual bit rate of the connection, look in
the Advanced > Communication Status and Statistics > Wireless Status menu of the
CLI. If the quality of the RF link degrades severely, the actual bit rate could be lower
than the manually configured one.
The available bit rates for the S4200 device are:
Band Channel width Bit rates (Mbps)
2.4 GHz 20 MHz 6, 9, 12, 18, 24, 36, 48, and 54

72 Verint Video Intelligence Solutions
Nextiva S4200 Series User Guide
Once the device is operating properly, Verint strongly recommends to change the
configured bit rate from Auto to the actual bit rate of the connection. This way, the
wireless communication will be more stable in the presence of changing atmospheric
conditions or other RF interferers. To know the actual bit rate of the connection, look in
the Advanced > Communication Status and Statistics > Wireless Status menu of the
CLI. If the quality of the RF link degrades severely, the actual bit rate could be lower
than the manually configured one.
The available bit rates for the S4200 device are:
Band Channel width Bit rates (Mbps)
2.4 GHz 20 MHz 6, 9, 12, 18, 24, 36, 48, and 54

If the MAC mode is SPCF, the parameters are:
If the MAC mode is 802.11, the parameters are:
2. In the Passkey Entry Format list, select the format for the wireless and WEP
passkeys. The available values are String and Hexadecimal.
74 Verint Video Intelligence Solutions
Nextiva S4200 Series User Guide
3. In the Tx Power Scale list, select the level of emitting power of the device radio. The
default level is the maximum allowed in your country for the configured antenna. If
your system operates with a comfortable RF margin (15 dB), you may reduce the
emitting power to lower the noise generated on the other RF systems located nearby.
The available values are:
Maximum—The maximum allowed.
50%—The power is reduced by 3 dB.
25%—The power is reduced by 6 dB.
12.5%—The power is reduced by 9 dB.
4. In the Sensitivity Threshold list, select the minimum signal level perceived by the
radio of the device. Reducing the sensitivity of the radio enables unwanted “noise” to be
filtered out. A safe value is 10 dB below the current received signal level (displayed in
the CLI in the Advanced > Communication Status and Statistics > Wireless Status
menu). The default value, Normal, represents the most sensitive context. You must be
careful not to reduce the sensitivity to a level where the device would not “hear” its
legitimate correspondent. The other available values are -80 dBm, -75 dBm, -70 dBm,
and -60 dBm.
5. In the Minimum Margin box, enter the difference in dB between the actual signal
received by the device and the minimum signal required by a given bit rate to correctly
receive data on the RF link. The default minimum margin is 15 dB. This parameter is
used when the transmission bit rate is set to Auto. It only appears if the MAC mode is
SPCF.
6. In the Enable Radar Detection on Slave list, indicate whether radar detection is
enabled on slave devices in a DFS context; this parameter only appears if the selected
RF band supports DFS and if the MAC mode is SPCF. For more information on radar
detection, see page 29.
7. In the Number of Frames per Burst box, enter the maximum number of data frames
that are sent on the wireless network by a slave device each time its master polls it.
The value range is 1–8. Default is 8. The performance of the wireless network increases
as the number of frames increases.
Typically this value is set on a slave device to configure its connection to its master.
Setting this value on the master limits the maximum number of frames for all slaves
connected to it. If a slave has a lower limit than the value provided by the master, the
lowest limit will be taken.
8. In the Maximum Polling Latency box, enter the maximum delay between two polls
for the same slave, in milliseconds. The value range is 10–255. Default is 255: It
indicates that there is no latency control and provides the maximum performances.
SPCF is a polling protocol. Each slave is polled one after the other. The polling latency
is the time taken to poll all the connected slaves. For delay sensitive applications like
PTZ, it can be useful to have control on this delay. When enabled, polling latency
control will automatically adjust the maximum number of frames per burst for each
slave so that the maximum latency delay is respected. However, doing so reduces the
maximum performances of the wireless network.
9. In the IP Multicast Forward from this Interface list, indicate whether multicast
data coming from the wireless network is allowed to be sent to the Ethernet network.

band. The available values are Indoor, Outdoor, or Indoor/Outdoor. The available
frequency channels are different for each location regulation. The default factory value
for most countries is Indoor/Outdoor.
Under the RF regulation, a device programmed to be used only indoors must not be
installed outdoors, and vice versa.
To know which frequency channels are available in your country of operation in each of
the three operation modes, see the “Compliance” appendix on page 136.
11. In the DFS/TPC Adjacent Channel Removal list, indicate whether the available list
of frequency channels is reduced to avoid the use of adjacent channels. For more
information, see page 29. This parameter only appears if the MAC mode is SPCF.

HTTP requests will be made. Default in all web applications is 80.
3. In the Web Streaming Method list, select the protocol used for transmitting video.
The available values are:
VSIP/UDP—A legacy protocol, using the proprietary VSIP video protocol over UDP.
The preferred UDP mode is RTP/UDP.
VSIP/TCP—A protocol using the proprietary VSIP video protocol over TCP. This
protocol guarantees proper reception of video packets, but could slow down the
effective frame rate to an unacceptable level (default).
Multicast UDP—A protocol using RTP (Real Time T r ansport Protocol, RFC 3550) over
UDP that transfers video to a multicast group. It does not guarantee proper
reception of video packets.
RTP/UDP—A protocol using RTP (Real Time Transport Protocol, RFC 3550) over UDP
that transfers video to a unique recipient. It does not guarantee proper reception of
video packets.
