2. SCOPE
This document aims to provide a user manual for the setup and installation of the SR
sensor by Magos Systems. The manual provides information on mechanical structure
and interface, installation procedure and guidelines, interface to managing system.
Please read the entire document prior to the installation and or use of the product.
2.1 PROFESSIONAL INSTALLATION INSTRUCTIONS
2.1.1 INSTALLATION PERSONNEL
The SR Radar is designated for installation by technicians/system integrators who have
received training by Magos Ltd. Only. It is not designated for the casual consumer or
installation by
“lay-men”. If you have not received proper training please contact Magos Ltd or visit
our website (www.magosys.com) for a list of authorized installation personnel.
2.1.2 INSTALLATION LOCATION
The product shall be installed at a location where the radiating antenna can be kept at
least 2m from a nearby person in normal operation conditions.
Microwave radiation does not propagate in a straight line but more as an elliptic sphere
between the radar and the target: This is known as a Fresnel zone and should be kept
clear of blocking objects to maximize radar performance.
The ground is the major problem but also other objects in the area like trees, buildings
and large vehicles can be a problem.
Therefore, please use the following table as a minimum recommended radar installation
height as a function of maximum detection range wanted for the radar:

2.3 SYSTEM OVERVIEW
SR outdoor perimeter defense sensors are designated for outdoor installation and use
only. It provides high accuracy, real-time location and speed data on detected targets.
The SR series is a radar technology based sensor. This means that it transmits low
power (less than 100mW) RF signal in the C-Band frequency and inspects the returned
signal. Radars detect movement within the transmitted beam coverage area, based on
modification in the returned signal and Doppler induced frequency detection. The SR
series contains no moving parts and relies on a multi-channel antenna array and digital
beam forming technology to determine target azimuth. This fact increases scan rate
capabilities and thus enhances detection probability and s detection performance in
general. In addition it contributes to MTBF increase making the entire system more
reliable. Finally as an RF based sensor the SR exhibits superb immunity to lighting,
visibility (FOG, Smog), weather (rain, snow) and other environmental conditions.
The SR implements all data processing, detection and target tracking algorithm
intrinsically, and reports the tracking results via Ethernet UDP protocol to the host
computer approximately twice per second.
Unlike most radars, the SR Series support "zero Doppler" detection – meaning that it
can detect very slow moving targets (crawlers etc) and tangent moving targets. Static
objects are not reported as targets since each target must travel a certain minimum
target to be considered as a target, however a moving target that was tracked and stop
moving will still be detected.
Radar coverage area is nominally 120° in azimuth (horizontal plane) and 30° in
elevation. A more accurate description of the radar coverage area can be found in
Figure 11. Note that in similar to all transmitting/receiving antennas and devices, the SR
also exhibits low gain to areas outside the stated coverage area (above 60° to the left
or to the right of the face of the radar and even to the back of the radar). This results in
some wanted and unwanted phenomena for example:
●Zero range detection: even when installed on very high (>10m) poles with zero
tilt angle – the radar might still detect targets moving on the ground directly
below it (allegedly increasing coverage in elevation to 90 degrees below the
horizon).
●Near range disturbances: large moving targets (or metallic objects acting as
reflectors) in the near vicinity of the radar (up to 10 meters away from it for
human up to car sized targets) outside the area of coverage and even directly
behind the radar might be detected by the radar and falsely interpreted as
targets moving within the coverage area.

4. MECHANICAL INSTALLATION
4.1 INSTALLATION RESTRICTIONS AND LIMITATIONS
In order to properly install the SR radars and integrate it into an active, efficiency
protection system, it is imperative that the user will first understand some basic rules
regarding radars in general and specifically regarding the SR radars. Prior to sensor
installation it is imperative that the user reads the following list of limitations and
restrictions and ensures that the intended installation site is suitable for installation.
When in doubt please consult with Magos representatives.
The following limitation and restriction should be considered prior to installation:
●Environment: Radars are based on line-of-sight detection. Any obstacles hiding
or partially hiding areas from the radar will not be properly protected. This
include obvious obstacles such as walls, buildings, hills etc, but also includes
less obvious obstacles such as light foliage, low bushes etc., where target is
only partially obscured from the radar. In such case detection performance is
reduced.
●While the SR radar features "zero-doppler" detection, maximum detection
ranges for tangent moving targets (moving targets that remain at a constant or
near constant distance from the radar) or for crawlers are typically reduced
compared to radial moving targets. This occurs in areas that are not clear of
obstacles such as bushes, trees and other vegetation.
●The SR radar does not implement target classification – which means that cars,
human walker large animals and sometimes small animals are all declared as
targets.
●The SR’s instrumental resolution in azimuth is ~5°, and in range it is ~0.4m.
Therefore target separation capabilities are ~1m in range and 7° in azimuth. This
means that two or more targets moving within less than 1m difference in range
from each other and less than 7° will be declared as single target, and the
reported location will be near the center of the group. Note that for single target
location accuracy is much better than resolution, and reach less than 1° in
azimuth and approximately 0.1m in range.
●As mentioned earlier the SR series might exhibit disturbances and "ghost"
targets as a result of large returned signals. This occurs when a very large target
(car/ truck etc.) moves in the vicinity of the radar (30m away or less, and 5m
away or less for human targets) even outside the stated coverage area.
Therefore it is recommended to install the sensor in unpopulated, isolated spots
(or alternatively use high poles to distance the radar from ground movement).

●The SR in similar to all radar based technologies relies on returned signal to
interpret target location. If the coverage area contains metallic objects (cars,
large pipes, fences etc) or non-metal surface (straight walls, buildings) this
might result in multiple reflections (in similar to looking at a mirror) from a signal
target, arriving at the radar from multiple angles. This means, for example, that if
the radar is set to protect and area containing a metallic fence, a target moving
at one side of the fence might be detected by the radar as 2 targets moving
from both sides of the fence.
●In general water is non-transparent to RF signals. A consequence of this fact is
that when the SR radar is positioned to cover an area containing large bodies of
water, large waves and other disturbances in the surface of the water might be
interpreted by the radar as moving targets.
●For safety reasons it is restricted to install the radar in marine type environment.
4.2 GENERAL INSTALLATION GUIDELINES
The SR radar sensor is very simple to handle and install.
Using the four holes on the back, the unit may be assembled either using one of
Magos’ solutions or any other means of securing the unit in the desired location.
IMPORTANT
Warranty does not cover water damage caused to the
connector. In order to avoid such damage the cap must be
attached whenever a cable is not plugged in.
Whether using the cable or the cap ensure that they are
securely connected by twisting them until firmly locked.
General guidelines for assembly:
●Figure 2 outlines the mechanical dimensions of the unit and mounting holes,
and the electronic connector location. Holes are compatible to 1/4’’-20X1/2
screws. Screws and mounting brackets can be purchased separately from
Magos. The brackets and their use are depicted in: Figure 3 and Figure 4 for
installation on a tripod, or Figures 5-7 for wall/mast/pole mounted installation.
●When using Magos’ brackets or any other bracket ensure all 4 screws are used.
During installation make sure all screws are properly fastened, and are installed
with spring washers and washers. Otherwise Magos is not responsible to

damage caused to the unit or people that might result from the detachment of
the sensor unit under harsh wind conditions.

Carefully choose the area of installation: make sure that the coverage area of the unit is
a sparsely populated area with minimum human traffic. In addition avoid positioning the
unit in the vicinity of large metal (or other) reflectors that might block line of sight to the
entire coverage area or otherwise hamper sensor performance. Figure 8 and Figure 9
depict general rules of thumb for unit placement. It is strongly recommended that
customers new to radar technology in general and the SR specifically would perform a
Page 13 © Copyright 2017, Magos Systems. All Rights Reserved

preliminary site survey in cooperation with Maogs' sales & support representatives to
ensure that the protected area is suitable for coverage using the SR.
Figure 9: Proper Installation on tripod
Figure 10: Proper Installation on fence
Aim the center of the sensor towards the center of the area of interest. Refer to Figure
10 for elevation and azimuth angle coverage relative to the unit. Figure 11
demonstrates typical detection performance – maximum range as a function of angle of
approach from the birds-eye view. Ensure that sensor is level with the ground,
otherwise sensor coverage area might be reduced depending on the sensor’s elevation
angle coverage and the degree of tilt relative to the ground.

Recommended installation height is 3-9m. Bellow 3m user might experience
degradation in sensor performance. Above 9m there might be a “dead-zone” in the
vicinity of the sensor in accordance with the sensor’s elevation angle coverage. In order
to achieve best performance refer to Table 1 and Figure 12 for recommended tilt angle.

Make sure the sensor is stable and secure. The mounting solution should be stiff and
stationary under harsh wind conditions. As a general guideline, oscillations of more
than 3cm should not be allowed, or the unit’s performance might be compromised.
If several sensors need to be installed next to each other, we recommend a distance of
at least 1m between the sensors when not aimed at each other (back to back
installation). Avoid aiming the sensors at each other when they are installed with less
than 150 meters distance between them.
Failure to observe the above restrictions might result in sensor performance
degradation and in extreme cases might lead to irreversible damage to the sensor
units.
Connecting to the sensor: use outdoor weather immune cables. When cable is not
plugged in use the connector cap to maintain weather immunity. Magos is not
responsible to weather damage (corrosion etc.) caused by using improper
cables/failure to the use the cap when not installed. In such cases product warranty is
void. See chapter 5 for details on sensor electronic connection.
Ensure that the electronic connecting cable is firmly secured to the pole/wall or any
other contraption upon which the radar is installed in such a fashion that would not
allow it to dangle within the coverage area of the sensor. In addition make sure that the
cable securing method renders it resistible to strong winds and that it does not apply
excessive force on the connector.

5. ELECTRICAL INSTALLATION GUIDELINES
Electrical installation of the sensor consists of a simple cable connection on the radar
side. Figure 13 contains the electrical schema of this cable. For safety and warranty
reasons users must use only cables supplied by Magos. Users must also ensure that
that connector shielding on the RJ45 connector side is properly grounded.
Figure 15: SR500 External operation cable
5.1 POWER SUPPLY INTERFACE
Ensure that the SR Radar is powered only from an IEEE 802.3at Type 1 (802.3af) and
Type 2 certified POE injector/switch which is in conformance with all safety and EMC
standards that are relevant and applicable in your country. If you are unfamiliar with
such standards it is recommended that you contact Magos and enquire as to the
compatibility of the suggested power supply.
Electrical requirements of the power supply are 48V and 15W, according to IEEE
802.3at Type 1 (802.3af) and Type 2. Using power supplies that do not meet these
requirements and/or are not properly authorized for public use in your country is under
the sole responsibility of the user, and might result in unexpected sensor behavior or
even irreversible damage to the unit.
An example for such a POE supply can be found here: POE injector .Note that this is an
indoor unit that can be useful for initial sensor configuration only and cannot be used in
outdoor fixed installations.
