OUTDOOR PERIMETER INTRUSION DETECTION SYSTEM
User Guide – Preliminary Edition
1. Introduction
Welcome to Southwest Microwave’s new buried cable outdoor perimeter intrusion detection system –
MicroTrack – the most advanced buried cable sensor system available. MicroTrack is the first buried
cable sensor that is truly site-adaptive and can both detect and locate intruders. MicroTrack is a smart
sensor with an integral power and data network. It is patented and it is the first outdoor intrusion
detection sensor to use ultra wide band FS/PCM (frequency stepped, phase code modulated) technology –
the same technology used in radar altimeters.
MicroTrack is the latest member of Southwest Microwave’s Intrepid family of outdoor perimeter
intrusion detection products. And, like its cousin, MicroPoint, it also incorporates Sensitivity Leveling
and Free Format Zoning. MicroTrack is terrain following with the ability to go up and down hills and
around corners. It provides a large invisible detection field and operates in difficult environmental
conditions with a very high probability of detection and low false and nuisance alarm rate. MicroTrack
uses Multi-Segment Target Analysis (MSTA) – a new concept in sensor design enabling each sensor
cable to be divided into small subcells (each 1.1 meter (3.6 ft.) in length) to be independently adapted to
site conditions and analyzed. MicroTrack overcomes numerous limitations of past generation buried
cable sensors.
This User Guide provides instructions on site planning and how to install and operate MicroTrack.

MicroTrack User Guide 5 April 1, 2004
1.1 MicroTrack Security Applications
MicroTrack can be used to detect intruders entering and/or leaving a secure facility. It is typically
installed on the secure side of the facility and in close proximity to a fence (or wall). In high security
applications involving two fences (or walls), MicroTrack is commonly installed between the fences.
MicroTrack can also be installed in open areas provided there is some means, such as a low profile
courtesy fence (or wall) to limit access to the system, to avoid nuisance alarms from large animals and
passers-by. Typical site applications are listed and illustrated below.
• Military installations
• Parked aircraft areas
• Government facilities
• Nuclear power plants
• Electrical substations
• Equipment storage areas
• Pharmaceutical plants
• Correctional facilities
• Commercial airports
• VIP estates
• Oil, gas and petrochemical facilities
• R&D facilities
• Banking and computer centers
• Vehicle parking areas
• Communications facilities
• Border crossing area
1.2 MicroTrack Sensor Characteristics
The MicroTrack sensor consists of an electronics processor unit and two pairs of buried sensor cables. A
detection field is created around each pair of sensor cables for a distance of up to 200 meters, or a total of
400 meters per processor. The cables are buried in soil, asphalt, concrete or other burial medium. The
processor uses ultra wide band FS/PCM transmission to create an invisible electromagnetic detection field
around and along the cables. This approach provides a far superior probability of detection (Pd) and
lower false and nuisance alarm rate (FAR/NAR) compared to other sensors. MicroTrack can also
communicate with and provide power to a variety of auxiliary sensors.
MicroTrack detects walking, running, crawling, rolling and jumping intruders. MicroTrack will locate
intruders to within approximately five meters (16 ft.). It will also operate in unfavorable and changing
environmental conditions, including, rain, wind, snow, hail, fog, blowing sand and seismic effects. The
processor unit transmits radio frequencies between 20 and 30 MHz through one of the sensor cables
which acts as a transmit cable. The second sensor cable acts as a receive cable and provides information
back to the processor. This process creates an electromagnetic surface wave moving above the ground
surface and along the cables. An intruder crossing the cables significantly changes the surface wave, thus
altering the return signal on the receive cable. The processor unit compares the transmitted and received
signals in terms of phase and amplitude and declares an alarm when changes occur which match a human
intruder. MicroTrack will also detect tunnelers moving within one meter (3 ft.) of the sensor cable.
Detailed performance specifications for MicroTrack are provided in Appendix 1.
MicroTrack User Guide 6 April 1, 2004
1.3 MicroTrack Features and Benefits
MicroTrack provides a combination of features and performance benefits unequalled in other outdoor
sensors. These include:
• Invisible detection field – unobtrusive and covert
• Wide detection field pattern – volumetric high-security detection
• Terrain following – follows ground contours and goes around corners
• Target location – the ability to locate intruders anywhere along the cable
• Sensitivity leveling – the sensor adapts precisely to its installed environment so detection
sensitivity is uniform along the entire length of sensor cable
• Free format zoning – up to 50 detection zones per processor can be created in software
anywhere along the sensor cable(s)
• Secure power and data networking – power and data are transmitted on the detection
cables for each processor and auxiliary sensors
• Default calibration – a flat line calibration is used for quick initial system set-up
• Remote diagnostics via modem – for quick problem resolution and lower support costs
• Uniform sensor cable – the sensor cable is identical from one end to the other for easy repair
• Factory-made connections – for high reliability eliminates the need to install cable
connectors in the field
• Sensor cable configuration – fewer components make it easier to configure and install

1.4 Comparison to Past Generation Buried Cable Sensors
MicroTrack’s unique sensor design has achieved significant benefits when compared to some of the
application challenges and limitations of past generation buried cable sensors. Some of these benefits
have a significant impact on performance, some relate to broadening applications, while others relate to
ease of installation and commissioning, and consequently result in cost savings.

1.5 MicroTrack System Components
MicroTrack system components are presented in three categories: major hardware and software
components, installation and spare components and optional components. Additional details are included
in Section 2.
1.5.1 Major Hardware and Software Components
MicroTrack Processor (MTP)
The MTP is the principal component of the MicroTrack system. It provides all the electronic processing
for two-200 m (656 ft.) sensor cable sets for a total length of 400 m (1312 ft.). It is packaged in a black
metal EMI/RFI housing which must be installed in a weather-tight enclosure when used outdoors. Up to
eight (8) MTP’s can be linked together using MicroTrack Links. One MTP is powered by a 48 VDC
power supply and additional MTP’s share power and data through the sensor cable. A second power
supply is required when more than four (4) MTP’s are linked together.
MicroTrack Sensor Cable Assembly (MTC400)
An MTC400 sensor cable assembly consists of one spool of sensor cable and 20 m (66 ft.) of lead-in
cable. Cable junctions are factory made to ensure high integrity. A TNC connector is installed on the
lead-in cable to connect with the MTP. A MicroTrack Link is installed at the far end of the sensor cable
to link with the sensor cable assembly leading to the next MTP. MT400 cable assemblies are available in
two lengths: 105 m (344 ft.) MTC400-105, and 205 m (672 ft.) MTC400-205. They can be buried in soil,
concrete or asphalt. Labels are included to identify transmit and receive cables. Two MTC400 sensor
cable assemblies are required to make one sensor cable set.
MicroTrack Site Manager Software (MTS)
Site Manager Software consists of two Microsoft Windows™ based programs that run on a PC. One is
called Installation/Service Tool and the other is Drawing Tool.
1.5.2 Installation and Spare Components
MicroTrack Enclosure - Non-Metallic (MTE-NM)
This is a weather-tight enclosure used to house an MTP. It is a NEMA 4 enclosure made from fiberglass
or similar non-metallic material. It includes a tamper switch assembly, pre-drilled mounting plate,
hardware, and U-bolts t attach it to a fence post.
MicroTrack Enclosure - Metallic (MTE-ME)
This is painted steel weather-tight enclosure to house an MTP. It is also NEMA 4 rated and includes a
tamper switch assembly, pre-drilled mounting plate, hardware, and U-bolts t attach it to a fence post.
MicroTrack User Guide 9 April 1, 2004
MicroTrack Enclosure - Stainless Steel (MTE-SS)
This is stainless steel weather-tight enclosure to house an MTP in a high corrosion environment. It is also
NEMA 4 rated and includes a tamper switch assembly, pre-drilled mounting plate, hardware, and U-bolts
t attach it to a fence post.
MicroTrack Enclosure - Pedestal (MTE-PE)
A pedestal enclosure is used as an alternative to protect an MTP and provides a more discrete installation
by blending in with familiar enclosures. This pedestal is the same one used by the telephone and cable
TV industry. A protective cover is installed inside the pedestal over the MTP to further protect it from
rain, snow and dust. In addition, a pedestal mounting stake, mounting brackets, and a tamper switch
assembly will be provided.
MicroTrack Link (MTL)
MicroTrack Links are used to terminate the RF in one cable set while allowing power and data
communication to pass to the adjoining sensor cable set and to the next MTP. One MTL is attached to the
end of each of the four adjoining MicroTrack Sensor cables. Each MTL has three wires protruding from
the end (red for DC power, white for FSK data, and black for ground) which are connected to the next
MTL in the system (for connecting the two transmit cables together, and the two receive cables together).
MTL’s include an enclosure with circuit card, cable glands, potting compound and water-tight wire nuts.
MicroTrack Termination (MTT)
MTT’s are used to terminate the transmitted RF signal at the end of a cable set. They are used when there
is no adjoining cable set. [Note: a short MTT will be required for use at the MTP when only one sensor
cable set is used.]
MicroTrack Terminations are used at the far ends of the first and last cable sets in an open loop
configuration used to terminate the RF and data communications (assuming the system ends with a sensor
cable set and not an MTP). An MTT has one five (5) meter long black wire protruding from the end that
serves as the lead-out cable. This includes the PCB, lead-out wire, enclosure, cable glands, and potting
compound. An MTT is required for each sensor cable assembly, i.e., two MTT’s are required for a sensor
cable set.
MicroTrack Splice Kit (MTS)
An splice kit is used to repair a damaged section of one sensor cable. A kit includes two splice boxes and
potting compound. A length of MTC400 sensor cable is required and must be ordered separately.
MicroTrack Lead-in Cable Assembly (02A15909-A01)
This is 20 meters (66 ft.) of lead-in cable with ferrites and a factory-installed TNC connector. A splice
box with connectors and potting compound will be included and partially assembled onto the cable. Note
MicroTrack User Guide 10 April 1, 2004
that the Lead-in Cable Assembly must be replaced as a unit, never spliced or repaired. Cable labels are
included.
MicroTrack Sensor Cable (MTC400)
MTC400 sensor cable is used to replace sections of damaged sensor cable. It is available on spools of
105 m (344 ft.) or 205 m (672 ft.) for use with MicroTrack Splice Kits. Shorter cable lengths are
available on special order.
1.5.3 Optional Hardware and Software Components
The following optional components are available to complement MicroTrack.
Relay Module (RM)
Relay Modules are used to communicate with auxiliary sensors and other devices on the perimeter. Each
RM provides for six (6) relay inputs, six (6) contact outputs, four (4) analog inputs to various devices, and
12 VDC power output to auxiliary sensors. RM’s receive power from and communicate directly with an
MTP. Up to 15 RM’s can be connected to an MTP.
Map Monitor Software with PC and Color Monitor
Map Monitor software provides easy to use operator command and control for MicroTrack and auxiliary
sensors. It uses Microsoft Windows™ based software and a PC with a color monitor to display all sensor
zones on a custom site map. The Map Monitor communicates with all MicroTrack MTP and SIM units
and displays the precise location of an intrusion.

3. Site Planning and System Configuration
Site planning is an essential step to ensure MicroTrack is properly applied and configured to a specific
site. Site planning includes visiting the site, assessing site characteristics and defining the basic system
configuration. Once this step is complete we can proceed to detailed system configuration and layout
which includes defining what MicroTrack system components are required and how they will be
distributed around the site. The first step in this process is performing a site survey.
3.1 Site Survey
The purpose of conducting a site survey is to determine how MicroTrack can be best applied to the site,
determine the users installation preferences and operational needs, identify site specific situations
affecting the MicroTrack installation, determine the system components required, assess the need for
auxiliary sensors and interfacing with them, and define installation parameters, including the type of
equipment required, as well as time and cost.
Prior to conducting a site survey there are a few items which should be obtained and reviewed with the
end user, site manager or person responsible for site security.
• Obtain

Now you are ready to walk around the perimeter of the site, preferably with the end user, to assess
installation conditions and the best location for MicroTrack and auxiliary sensors, if required. Here are
the important steps to consider during the walk-around:
•
Select the path where MicroTrack sensor cable will be installed – typically along the inside of the
perimeter fence (or wall) or between two fences (or walls) – ideally, a distance from 10 to 15 feet
(3 to 4.5 m) from the fence. If there are no site drawings available,

MicroTrack User Guide 15 April 1, 2004
3.2 System Configuration and Layout
The second step in the site planning process is determining what MicroTrack components and how many
are required. Then we can define how they will be placed around the site.
3.2.1 Determining Total Sensor Cable Length
The first step is to determine the perimeter length of the sensor cable path. Exact measurements are
preferable. However, as a guideline, if the sensor cable set will be installed within 15 feet (4.5 m) of the
fence, for rough estimating purposes, use the total perimeter length of the fence line to estimate the total
length of sensor cable required.
Total Perimeter Length ≈ Total Sensor Cable Set Length
3.2.2 Lead-in Cable and Connectors
Each MTC400 sensor cable includes a 20 m (66 ft.) length of lead-in cable. The lead-in is factory
connected to the sensor cable and is installation-ready with factory installed TNC connectors for
connection to the MTP.
3.2.3 Determining the Quantity of Sensor Cable Assemblies per System
To determine the number of sensor cable assemblies required for a site we must first decide which length
of each cable set is preferred. There are two standard sensor cable lengths available:
MTC400-105, 105 m (344 ft.) long
MTC400-205, 205 m (672 ft.) long
Each sensor cable includes an additional five (5) meters (16 ft.) of sensor cable for a startup overlap with
the adjacent sensor cable set for the detection field to build up to its full height. Note that the five meters
used for startup are not to be counted when determining total sensor cable set length requirements. The
startup overlap is made only at the MTP.
The longer cable set is more cost effective. Note that cable sets are independent of detection zones and up
to 50 detection zones can be defined for every two sensor cable sets, i.e., 50 zones can be created of any
length for a distance of up to 400 m (1312 ft.) of sensor cable. Assuming the MTC400-205 cable
assembly is selected, the number of sensor cable sets and sensor cable assemblies required for a site is
determined as follows:
Quantity
200 m
Alternatively, if the MTC400-105 cable assembly is preferred,
Quantity
100 m
of MTC400-205 Sensor Cable Sets = Total Sensor Cable Set Length
of MTC400-105 Sensor Cable Sets = Total Sensor Cable Set Length
MicroTrack User Guide 16 April 1, 2004
Sensor cable sets can be customized on-site to any length between 10 m (33 ft.) and the maximum length
of 200 m (656 ft.). The number of cable sets should always be an even number to utilize the dual cable
set capability of the MicroTrack MTP.
Quantity

= 2 x
3.2.4 Determining the Quantity of MicroTrack Processor (MTP) Units
Each MTP can have two MTC400 sensor cable sets, and the maximum number of MTP’s per system is
eight (8). It is possible for an MTP to have only one sensor cable set provided a MicroTrack Termination
is installed on the unused side of the MTP.
Quantity
2
3.2.4.1 Network and Standalone Configurations
MTP’s can be used in one of two configurations: either network or standalone. A network system is
where a series of MTP’s are linked together so that power and data pass from one MTP to the next
through the sensor cable.
Quantity
An even number of cable sets should be used with one or more MTP’s. Shorter length sensor cable sets
can be used to close a perimeter if using 200 m (656 ft.) cable sets exceeds the required perimeter length.
One 48 VDC power supply can power up to four (4) MTP’s. A second power supply will be required for
additional MTP’s. An FSK repeater will be required when more than five (5) MTP’s are used.
If the perimeter length exceeds the “System” limit of eight (8) MTP’s, additional MTP’s can be installed
as a “second System” with a separate power and data link with from the Map Monitor (or alternative
alarm monitoring system) in the control center. There is no need to synchronize MTP’s or MTP
“Systems”.
A system is considered “standalone” when each MTP is independently powered and communicated with
from the control center.
3.2.4.2 Redundant Power and Data System Configuration
It is possible to configure MicroTrack with fully redundant closed loop power and data communications
as shown below in Figure 3.1. This feature ensures system integrity is maintained should a sensor cable

Up to five MTP units can be configured with redundant power and data.
Maximum
3.2.4.3 Positioning and Powering MTP Units
The first MTP should be positioned at a point on the perimeter closest to the control center to provide best
access for power and data communications. MTP’s are usually installed on or near the perimeter fence
and can be located up to 20 m (66 ft.) from the sensor cable set. Power and data connections are made
directly to the panel of the first MTP, while adjacent MTP’s have their power and data fed from one to the
other through the sensor cables.
There are two methods of powering MTP’s to provide for smart sensor data communications, and one
method which uses each MTP as an independent standalone sensor with simple alarm relay output, i.e., no
smart sensor data communications:
Option 1: Power one MTP directly from the control center and additional MTP’s via the sensor
cable; all with smart sensor data communications via the sensor cable (maximum of four (4)
MTP’s per 48 VDC power supply, and eight (8) MTP’s per System).
Option 2: Power each MTP independently with smart sensor data communications via the sensor
cable (eight MTP’s per System)
Option 3: Power each MTP independently and have separate and simple relay alarm output, i.e.,
the smart sensor data communications capability is not used.

3.2.6 Adding Auxiliary Sensor Inputs and Outputs to MTP’s
MicroTrack’s integral power and data capability can also provide output power and data communications
for auxiliary sensors. A list of typical inputs and outputs are as follows:
• Outdoor intrusion detection sensors, at gates, sallyports, roads or complete perimeter, such as:
Microwave at gates
MicroPoint fence disturbance sensor – a smart sensor
• Gate entry barriers and access control points
• Interior intrusion detection sensors, including alarm panels
• Perimeter lighting
• Closed circuit television cameras (CCTV), e.g., input to PTZ control
The following options are available for power and data communications with auxiliary sensors:
• Sensor Interface Module (SIM) – 8 relay inputs, 8 relay outputs, output power 12 VDC @ 150
ma, communications via RS232/422/485
• Sensor Multiplex Module (SMM) – 8 relay inputs, communications via RS485
3.2.7 When to use a Relay Module (RM)
Relay Modules are used to communicate with auxiliary sensors and other devices on the perimeter. Each
RM provides for six (6) relay inputs, six (6) contact outputs and four (4) analog inputs to various devices.
RM’s receive power from and communicate directly with an MTP. A maximum of 15 RM’s may be
connected to one MTP.
3.2.8 Sensor Cable Installation Components
Installation components are required to link sensor, terminate and repair cable sets. The following section
describes where they are used and how they are selected.
