CHAPTER 1 Overview
1.1 Product
The SmartSight™ 1000 is a professional video transmission product designed for the
CCTV (Closed Circuit Television) market. It offers a secure (encrypted using a Wired
Equivalent Privacy algorithm) signal 100 times more robust to interference than
conventional AM/FM analog systems. The system consists of a video transmitter
(S1000-TX) and a video receiver (S1000-RX).
1.2 Equipment
Your S1000 shipment should contain the following items:
• 2 - S1000 or S1000-24VAC modules (S1000-TX & S1000-RX)
• 2 - wall mounting bracket set
• 2 cable assemblies (P/N S1000-CA-9P)
• User’s manual.
The shipment may also contain the following options:
• 1 or 2 16 dBi gain antennas (S1000-PA)
• 1 or 2 15 VDC external power supply (S1000-PS)
• 1 or 2 Pole mount bracket sets (S1000-PM)
• 1 or 2 Junction Box with 24 VAC input (S1000-JB).

2.2 Applications
The current software version of the S1000 supports operation in point-to-point.
Future software upgrades will support transmission of video to multiple receivers as
well as retransmission of signal in none-line-of-sight application.
The S1000 supports 3 non-overlapping channels (channels 1, 6 and 11) or
operation of 3 simultaneous links within the same location. It is also possible to
support up to 6 links simultaneously with each of the six receivers installed at the
same location. However, this requires some site planning (see CHAPTER 4).
In most case, you will need to program a unique SSID (security ID) for each radio
system (see 4.2.4 to learn how to configure each module using a computer). As an
example, for 3 S1000 systems, 3 individual SSID are required. The table below
shows the configuration applied to each module:
Module Configured Channel Configured SSID
S1000-TX 1 1 SYSTEMA
S1000-RX 1 1 SYSTEMA
S1000-TX 2 6 SYSTEMB
S1000-RX 2 6 SYSTEMB
S1000-TX 3 11 SYSTEMC
S1000-RX 3 11 SYSTEMC

CHAPTER 3 S1000 System Configuration and Installation
3.1 S1000 system configuration
Your S1000 system is configured to operate right out of the box with the most
popular dome data port configurations (4800 baud, 8 data bits, no parity, 1 stop bit).
For added security, we recommend you change the SSID to your own secret SSID
and activate the WEP encryption and change the WEP key to your secret WEP key
before installing the system.
STEP 1 Initial Configuration
• Unpack the modules and set them side by side on a desk or table.
• Unpack the 2 cable assemblies (P/N S1000-CA-9P) and connect them to the
module (you must feel a positive click for the cable assembly connector to be
properly installed on the module)
• Connect the S1000-TX cable assembly DB-9 to a computer (if the DB9 has
been removed, refer to the table below to connect conductors properly) and
power the module (the STATUS LED should turn steady green and then
flashing green under normal operation; see the next section to understand
how this LED behaves under different operation conditions)

SmartSightTM 1000 User Manual / Rev 0.33
• Configure the S1000-TX SSID, WEP encryption key (if desired), radio
channel and serial port parameters (if required) via the computer (see 4.2.4
for configuration procedure)
• Connect the S1000-RX cable assembly DB-9 to the computer and power the
module (the STATUS LED should turn steady green under normal operation;
see the next section to understand how this LED behaves under different
operation conditions).
• Configure the S1000-RX parameters to the SAME parameters configured on
the S1000-TX
• You have completed the S1000 initial configuration. The system can now be
installed outdoors.
___________________________________________________________________
The S1000 integrates a single serial port. This port is used for both system configuration and data
communications (PTZ, access control or other). The serial port on the S1000 automatically detects
if it is connected to a computer (RS-232 serial port) or an RS-422 serial device. The user does not
have to configure the serial port for RS-232 or RS-422/485 operation or for configuration or data
communications.
__________________________________________________________________
3.2 Understanding the status led
The STATUS LED is a bi-color (GREEN-RED) LED which provides detailed
information on the system depending on whether the system is powering up, in
operation or the software is being updated.
Power-up sequence:
• Flashing Red (module is powering up)
• Steady Green (Application is started).
___________________________________________________________________
In very cold weather, the powering up sequence may take several minutes (up to 15 minutes at –
30°C). This is because the module must reach a certain internal temperature before powering up all
the electronics.
___________________________________________________________________
___________________________________________________________________
The following power-up conditions are abnormal:
1) LED not lit: Check the power supply and cabling, if power is available and the LED
stays off, call SmartSight technical support to obtain an RMA authorization.
2) Steady RED LED: There is an internal module error that prevents the unit from

6
starting normally. Power down and power back-up the module once. If the
condition persists proceed to a firmware upload (see CHAPTER 6) and if this fails
or the condition persists after the new upload, call SmartSight technical support
to obtain an RMA authorization.
____________________________________________________________________________
Tx After Power-up:
 Flashing Green (steady rate) if not communicating with another module.
 Flashing Green (various rate) if system communicating.
 Flashing Green with intermittent Red flash if the radio link is not very good
and there are video frames lost.
Rx After Power-up:
 Steady Green (if not communicating with another module).
 Flashing Green (various rate) if system communicating.
 Flashing Green with intermittent Red flash if the radio link is not very good
and there are video frames lost.
___________________________________________________________________
When communication is established between the transmitter and receiver, the GREEN LED flashing
rate is an indication of the number of frames transmitted every second. If the link is very good
the rate will be high. Under poor link conditions, the system will retransmit video frames constantly
and the frame rate will decrease as a result. If there are too many retransmission of video frames
some video frames may be lost and the picture quality may degrade momentarily (a flashing RED
LED indicates this state).
___________________________________________________________________
3.3 S1000 system installation
STEP 2 Installing the S1000 system in it’s final location
• Once your system is successfully configured it is ready to be installed
• Carefully review the site planning information presented in CHAPTER 4 to
optimize your system radio performance.
• If installing the S1000-TX on a light pole or mast, we suggest you use the
S1000-PM pole mount brackets and stainless steel clamps (for wall
mounting use the module side brackets).
• ALWAYS mount the S1000 modules with the industrial bayonet type black
connector pointing downwards.
• Connect the S1000-CA-9P cable assembly to the S1000 module and route
the cable to the dome or camera (all connections for the S1000-24VAC
model can be made inside a dome or motorized camera if 24 VAC is being
used for these devices). If the S1000-JB interconnection box is being used,
route all conductors to the S1000-JB first and then route all conductors from
the S1000-JB to the dome or camera).

7
SmartSightTM 1000 User Manual / Rev 0.33
• Cut-off the DB-9 connector from the cable assembly in order to connect the
serial port to the dome or camera PTZ port terminals. Refer to one of the
following tables (whether using RS-422/485 or RS-232) to connect the serial
port to the target serial device:

____________________________________________________________________________
The S1000 must always be installed with the black bayonet connector pointing
downwards. Failure to install the module properly can cause moisture to penetrate the
module and may void the warranty.
____________________________________________________________________________
Figure 2 Example of a pole
mount installation
STEP 3 Installing the optional S1000-PA high gain antenna
• The S1000-PA is supplied with an adjustable pole mount bracket. It is
designed for mounting on a mast or pole of 2-3 inch diameter.
• The S1000-PA includes a one (1) meter pigtail cable to connect to the S1000
module. We recommend the antenna be mounted above the S1000 module.
Screw the pigtail connector (called an SMA connector) to the S1000 antenna
port and tighten with a small adjustable wrench (do not over-tight to avoid
damage to the connector)
• 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 S1000-PA antenna is shipped with
waterproofing potty and electrical tape. We recommend you apply the potty
around the two junctions between connectors at both the antenna and
module end and wrap 2-3 layers of electrical tape around the potty.
• Carefully align the S1000-PA antenna with the other antenna so that both
antennas are in perfect line-of-sight.

SmartSightTM 1000 User Manual / Rev 0.33
CHAPTER 4 Proper RF and Network Planning
The S1000 offers a robust and highly reliable spread spectrum wireless link, which can
operate up to 4 miles line-of-sight with appropriate installation.
For best operation, the system(s) must be properly planned (see section 4.1) and the
antennas must be installed in such a way as to obtain a line-of-sight link (see section 4.2)
4.1 Network Planning
4.1.1 Co-locating up to 3 systems
Three (3) S1000 can be co-located without special consideration for antenna
placement and antenna type. The following steps must be taken to operate three (3)
systems in the same area (failure to do so will cause interference between systems)
• Assign a unique SSID for each system (use any 4-32 characters for this ID). The
default SSID of each S1000 shipped is ‘SMARTSIGHT’.
• Assign channel 1 to one system, channel 6 to the second system and channel 11
to the last system.
4.1.2 Co-locating up to 6 systems (360 degree coverage)
If you are installing up to 6 S1000 receivers on the same mast and they are pointing
in different directions (at least covering 270 degrees), here is the procedure to use:
• Install the optional antenna S1000-PA on each S1000-RX (the integrated
antenna does not offer sufficient isolation to be used at the S1000-RX end in this
application).
• Assign a unique SSID for each system (use any 4-32 characters for this ID). The
default SSID of each S1000 shipped is ‘SMARTSIGHT’.
• Assign each system with a separate channel as shown in the table below:

10
Module Configured Channel Configured SSID
S1000-TX 1 1 SYSTEMA
S1000-RX 1 1 SYSTEMA
S1000-TX 2 3 SYSTEMB
S1000-RX 2 3 SYSTEMB
S1000-TX 3 5 SYSTEMC
S1000-RX 3 5 SYSTEMC

S1000-TX 5 9 SYSTEME
S1000-RX 5 9 SYSTEME
S1000-TX 6 11 SYSTEMF
S1000-RX 6 11 SYSTEMF
• Install the systems with the co-located channels (as an example channels 1 & 3,
channels 5 & 7 or channels 9 & 11) back to back or as close to back to back as
possible (as illustrated in Figure 3 below):

SmartSightTM 1000 User Manual / Rev 0.33
4.1.3 Co-locating up to 6 systems (less than 180 degree coverage)
If you are installing up to 6 S1000 receivers on the same side of a building or on the
same mast and they are pointing within the same direction (within 180 degrees
direction of each other), here is the procedure to use:
• Assign a unique SSID for each system (use any 4-32 characters for this ID). The
default SSID of each S1000 shipped is ‘SMARTSIGHT’.
• Assign two pairs of S1000-TX and RX modules on the same channel as shown in
the table below:
Module Configured Channel Configured SSID
S1000-TX 1 1 SYSTEMA
S1000-RX 1 1 SYSTEMA
S1000-TX 2 1 SYSTEMB
S1000-RX 2 1 SYSTEMB
S1000-TX 3 6 SYSTEMC
S1000-RX 3 6 SYSTEMC
S1000-TX 4 6 SYSTEMD
S1000-RX 4 6 SYSTEMD
S1000-TX 5 11 SYSTEME
S1000-RX 5 11 SYSTEME
S1000-TX 6 11 SYSTEMF
S1000-RX 6 11 SYSTEMF
• Install the systems that share the same channels as close together as possible
(as illustrated in Figure 4 below). Each two systems will now share the radio
bandwidth available per channel.

12
Figure 4 Example of co-located systems with each 2 systems sharing one channel
4.1.4 Co-locating systems on different sides of a building
If you are installing S1000 systems on different sides of a large building or building
complex, you may be able to install more than 3 systems as long as two (2) S1000
systems that use a set of co-located frequencies (as an example channels 1 & 3) do
not offer a line-of-sight view to each other. Here is the procedure to use:
• Assign a unique SSID for each system (use any 4-32 characters for this ID). The
default SSID of each S1000 shipped is ‘SMARTSIGHT’.
• Assign each system with a separate channel as shown in the table presented in
section 4.1.2 above.
• Install the systems with the co-located channels (as an example channels 1 & 3,
channels 5 & 7 or channels 9 & 11) in areas that do not offer a line-of-sight view
to each other (for example on opposite side of the building).

4.2 RF Planning
Successful operation of a S1000 network lies on the proper installation of the
wireless antennas. Such installation requires:
1. Evaluation of the location
2. Evaluation of antenna requirements
This section presents a step-by-step approach to completing the phases outlined
above.
4.2.1 Evaluation of the location
Unless it is a very short link distance (less 500 feet) the path between the two
antennas must be free of obstacles that could disturb propagation. Such path is
called a line-of-sight path. If there are obstacles, radio waves will be in part
absorbed and in part diffracted by the obstacles (multi-path fading). Even if
operating in such circumstances, links could be established. However, results
are highly unpredictable.
The first requirement of a successful link is therefore a clear line-of-sight path.
There is a second requirement related to the beam-width of a radio signal. The
beam-width of a radio signal transmitted between two antennas is an elliptical
area immediately surrounding the visual path (see Figure 5). It varies in
thickness depending on the length of the signal path. The region outlined by this
beam-width is known as the first Fresnel zone. The Fresnel zone is always
thicker at the mid-point between the two antennas. Therefore a path that
appears to be a perfect line-of-sight path between the base and a remote station
may not be adequate for a radio signal.
In practice, it has been determined that a radio path can be considered a line-of-
sight path if it has a clear opening through 60% of the first Fresnel zone (0.6 F1).
The table below presents the value of 0.6 F1 for various signal path distances. A
common problem encountered in the field and related to the 0.6F1 clearance rule
is a building obstruction. The proposed visual path may just barely clear a
building but the “radio line-of-sight” won’t. In such 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.

At 2.4 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.

4.2.2 Evaluation of antenna requirements
SmartSight offers two type of antennas to meet various distance requirements of
clients, the integrated 8.5 dBi patch antenna or an external 16 dBi gain patch
antenna (option S1000-PA). These can be combined together to offer the
following combinations and associated system range:
Range S1000-TX Antenna Gain S1000-RX Antenna Gain
4 miles 8.5 dBi 8.5 dBi
7 miles 8.5 dBi 16 dBi
15 miles 16 dBi 16 dBi
Note: The above ranges are specific to a S1000 system configured at 1Mbps.
The range is reduced by 30% at 2 Mbps data rate.
4.2.3 Coping with Interference
In most countries, the 2.4 GHz license free band is not regulated by a government
agency and this absence of frequency coordination can result in interference
