Warning: If you connect multiple devices on the same 24V AC power supply, always wire
them the same way: The red power wires of all devices must be on the same power supply terminal. Since the black power wire of the device is internally connected to its chassis (earth), swapping the power connection scheme from device to device will short out the AC power supply.
Warning: You can install third-party equipment with an earth-referenced power input on
the same power source as the devices. To do so, you must connect the earth-referenced terminal of the equipment to the same AC terminal as the black wire of the devices. Failing to do so will short out the AC power supply.

Overview

The S1100w allows digital video transmission over license-free and licensed bands. It delivers high-quality MPEG-4-based video at 30 frames per second in NTSC (25 in PAL) over local and wide area networks (LANs and WANs). This wireless edge device is built on open standards to provide long-term investment protection.
Combined with a Nextiva S3100 multipurpose outdoor wireless device or a commercial
802.11 access point, the S1100w enables analog CCTV extension over the enterprise’s network at a cost lower than that of laying new cables. The S1100w also allows the migration of analog CCTV cameras to an IP network.
Note: The S1100w edge devices require professional installation.
Verint Video Intelligence Solutions 1
1: Overview

About the S1100w

The S1100w devices come as transmitters only. You can buy 12V DC or 24V AC devices. The S1100w covers the 2.4 GHz and 5 GHz frequency bands in North America and Europe.
It also covers the 4.9 GHz public safety band in North America. Unless otherwise specified, the word S1100w refers to any of these devices. Each device is configured to operate, right out of the box, with the most popular camera
data port configuration (4800 baud, 8 data bits, no parity, 1 stop bit).

Security

Every S1100w 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 (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 the audio and video data.

Video

The S1100w has one video input with two encoders.
The video frame rate of the edge device can be:
NTSC—1 to 7, 10, 15, or 30 frames per second (fps) PAL—1 to 6, 8, 12, or 25 fps
2 Verint Video Intelligence Solutions
Nextiva S1100w User Guide
The S1100w devices can have the following video resolutions and maximum frame rates (in frames per second), using the NTSC (PAL) format:
Resolution Number of columns Number of lines Maximum frame rate
NTSC/PAL NTSC PAL NTSC PAL
QCIF 176 128 144 30 25 CIF 352 240 288 30 25 2CIF 352 384 448 30 25 2CIFH 704 240 288 30 25 4CIF 704 480 576 15 12 All lines 352 480 576 30 25 2/3 D1 480 480 576 15/30 * 12/25 * VGA 640 480 576 15/30 * 12/25 *
* Without noise, I/Os, and other factors affecting quality, the device can achieve the highest frame rate.
For more information about these video parameters, refer to the SConfigurator User Guide.

Verint Video Intelligence Solutions 5
2: System and RF Planning

Frequency Bands and Channels

The S1100w 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 S1100w 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 S1100w 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. For the S1100w, 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 S3100 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 (described on page 42). For example:
S3100
You can colocate many wireless cells if you respect certain conditions (see page 13).

802.11 Support

Starting at firmware version 4.0, you can use the S1100w devices with commercial
802.11-compliant access points. To support this new protocol, the 802.11 MAC (Media Access Control) mode is introduced. This mode is available in all frequency bands (2.4 GHz,
4.9GHz, and 5GHz). The S1100w in 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.

For more information about the TLS (Transport Layer Security) protocol, refer to RFC 2246 at http://www.ietf.org/rfc/rfc2246.txt
.
The supported encryption methods are:
WEP AES-CCMP TKIP Auto-select—The device automatically chooses the best available encryption scheme.
The wireless parameters associated to 802.11 differ from those of the SPCF mode. For more information about these parameters, see page 41 for the command line interface or refer to the SConfigurator User Guide.
Be aware of the following limitations in using S1100w devices in a 802.11 environment:
The S1100w will not be able to connect itself to an S3100. 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. It is assumed that the network administrators wanting to add S1100w 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 S3100 using 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 S1100w device and the access point in each cell. However, the S1100w devices can be completely hidden from one another.
Verint Video Intelligence Solutions 9
2: System and RF Planning

Point-to-Multipoint Application

A point-to-multipoint application is a wireless cell made up of an S3100 access point (the master) and several S1100w transmitters (the clients). Here is a typical point -to-multipoint system:
S1100w
S3100
For example, to associate three S1100w devices to one access point, you need to:
1. Assign the same wireless passkey to the S1100w devices and the S3100 access point.
The wireless passkey must be different from that of other colocated cells, if any.
2. In a non-DFS context, assign a frequency channel to the S3100 device. In a DFS
context, the master device will automatically select a channel.
The associated S1100w devices will automatically use their master’s channel.
3. Install the S1100w devices such that each one has a clear RF line of sight with the
S3100 access point. For the configuration and installation procedure, see page 23.

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 S1100w transmitters have the same firmware versions as their associated master; however, from version 2.60 and up, the devices are fully compatible (for example, an S1100w at version 4.0 with an S3100 at version 3.62).
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 upgrade procedure. One step at a time, get closer to the computer.
10 Verint Video Intelligence Solutions
Nextiva S1100w User Guide
For example, consider the following setup:
S1100w 1
S3100 3 S3100 2
S3100 1
S1100w 2
You should update 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 documentation of the Verint software you are using.

Video Bit Rate and Data Throughput

You can theoretically connect up to 16 S1100w devices to a master access point in a wireless cell. In practice however, video quality , fr ame rate, an d system layout can limit the number of devices that a single master access point can support.
Each time multiple client devices are connected to a master S3100, the available bandwidth is divided equally between the connections. For example, three S1100w clients connected to a master on a 6 Mbps link each have 2 Mbps throughput.
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:

The S1100w 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).
TPC
If the country of operation of the S1100w 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 46).

DFS
To follow the DFS (Dynamic Frequency Selection) regulations specified by ETSI for the selected country, it is the master S3100 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 when the other device is in normal operation.
The boot sequence of client (transmitter) devices is:
Unit initialization (3 seconds)
1
Roaming (2-25 seconds)
2
Normal operation
3
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 device runs normally on the selected frequency
channel.

Colocated Cells

You can operate many wireless cells in the same location, provided you follow guidelines relative to frequency channel, wireless passkey, and distance.
Regarding frequency channel, you cannot manually select one in the 5.40–5.725 GHz band in Europe; for the detailed procedure, see page 16.
The wireless passkeys of colocated cells must be different from one another, regardless of their frequency channels.

Distance Limitations

The distance limitations between devices 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). If using adjacent channels, see page 65 for the recommendations on the minimum
distances to respect. To reduce radio interference possibilities between two adjacent frequency channels,
ensure that the maximum margin between the emission of the two wireless cells is
25 dB; for more information, see Appendix F on page 65.

4.9 GHz Band in North America

Depending on the channel width (20, 10, or 5 MHz), you can colocate 2, 4, or 10 wireless cells respectively. For the available channels in each of the three scenarios, see page 7.
The following example presents three wireless cells with 10-MHz channels. To install such a system, you have to:
1. In each cell, assign the same wireless passkey to the S1100w devices and the S3100
access point. The wireless passkey must be different from that of the other cells.
2. Assign a different frequency channel to each S3100 device; the associated S1100w
devices will automatically use their master’s channel:

with its associated S3100 access point.

5 GHz Band in North America and 2.4 GHz

In the 2.4 GHz band in North America and Europe, you can use the three independent channels (channels 1, 6, and 11) to colocate wireless cells. In the 5 GHz band, all channels are independent.
A typical colocation example is three wireless cells. To install such a system, you have to:
1. In each cell, assign the same wireless passkey to the S1100w devices and the S3100
access point. The wireless passkey must be different from that of the other cells.
2. Assign a different frequency channel to each S3100 device; the associated S1100w
devices will automatically use their master’s channel. For example, in the 5 GHz band:

5 GHz Band in Europe

The maximum number of colocated cells corresponds to the number of channels in the available frequency bands that can be used outdoors. For instance, in most countries of Western Europe, you can have up to 11 colocated cells in the 5.40–5.725 GHz band. However, because the master devices must see each other in a DFS context, the variety of supported setups is limited.
In this context, you can easily install up to five cells. 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. You have to:
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 S3100 Series User Guide.
3. Position the devices so that there is at least 3 feet (1 meter) between each antenna.
4. In each master device, set a different starting order: 1 for the first device, 2 for the
device next to it, 3 for the third one, and so on. Installing more than five 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. Therefore, you should contact the Verint Video Intelligence Solutions project engineering group for assistance.

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.

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.
To establis h an RF line-of-sight path, you must take into account the beam width of the radio signal transmitted between the two antennas. This beam width is an elliptical area immediately surrounding the visual line of sight. It varies in thickness depending on the length of the line of sight; the longer the length, the thicker the beam width becomes.
The region outlined by the signal beam width 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.
Visual line of sight First Fresnel zone (F1)
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 (mi./km)
1 / 1.6 14 / 4.2 9.8 / 3.0 9.5 / 2.9 8.9 / 2.7 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
2.45 GHz (feet/m)
4.9 GHz (feet/m)
5.3 GHz (feet/m)
5.8 GHz (feet/m)
Earth curvature effect (feet/m)
For distances under seven 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). For help, consult the Verint Video Intelligence Solutions Support group.
