warnings carefully before using this series product and keep this user
manual well for future reference.
Electrical Safety
● All installation and operation should conform to local electrical
●safety standard.
● The power supply shall conform to the Safety Extra Low Voltage (SELV)
●standard, and DC 12 V power supply shall meet requirements of
●IEC60950-1. Please note that power supply shall subject to the require
●ment specified on radar label.
● Make sure the power electrical safety before operating the device.
● A readily accessible dissembling disconnect device shall be incorporated
●in the wiring of the building.
● Prevent the power cable from being trampled or pressed, especially the
●plug, power socket and the device adaptor.
● We assume noliability or responsibility for all the fires or electrical shock
●caused by improper handling or installation.
Environment
● Hard ground is the best choice for detection area, such as cement
●ground.As for the ground covered with vegetation,make sure the height
●of vegetation is less than 20cm.
● Make sure the detection area is not blocked by any vegetation, trees,
●buildings or vehicles etc.
● Make sure there is no electromagnetic interference around the installa-
●tion area and in the radar detection area, such as air conditioner external
●unit, high-tension transformer and so on.
● Please transport, use and store the device within the range of allowed

2.3 Radar Installation Direction
The installation direction of radar is crucial to measurement accuracy Please
make sure the installation direction is correct. The lateral view of the radar installa-
tion is shown in Figure 2-3.
2.4 Installation Guide
① Radar is installed in front of the detection area and aligns with the center of alert
area, as shown in Fig. 2-4.
Generally, the radar antenna plane shall be installed vertical to alert area in order
to guarantee the precision of the radar; besides, it needs to be installed at a certain
height, which normally is recommended to be 1~3m.

● Radar installation in the tested area ahead, radar normal alignment warning area
center.
③
Scenario II: perimeter protection scenario (airport, terminal, etc.)like figure 2-8.
● Radar set up against the side of the fence, above position close to the wall or
fence is best (above).
● The radar installation height is recommended to be 2 meters, which can be
adjusted according to actual needs but not to exceed 6m.
Radar detection blind area is different for different installation heights, generally
radar installation height no more than 3m or 4m is recommended; If the radar is
installed directly above the fence, it is recommended that the radar installation
height be between 0.5 and 1 meters directly above the fence.
The camera installation height be 3 to 6 meters.
● Radar installation of normal and parallel to the wall:
If the monitoring focus is on the inner side of the fence, shift the radar horizontal
angle to the inner side of the fence by ≤5°.
If the monitoring focus is on the outside of the fence, shift the radar horizontal
angle to the outside of the fence by ≤5°.

2.5 Bootup Description
Please refer to the Installation Guide to use the radar, connect the cable well accord-
ing to port definition after completing installation. The radar will generate brief signal
of the di sound fourth after powering on the system, which means the system is
normally launched. Then you can read the protocol data from the Ethernet port.
Device Wiring and Connection
3.1 Device Wiring
Note：
● The following figure which shows the device installation is for reference only.
Please refer to the actual device wiring instruction for more details.
● Please refer to below operation if network waterproof connector need to be
installed(optional)
Waterproof network connector(optional) is shown as Fig. 3-1

3.2 Device Connection
Before your radar connection:
①Make sure your radar and computer are connected to the same LAN.
②Make sure your computer and device are on the same subnet (192.168.10.xx).
③Radar factory default IP: 192.168.10.123, web client radar login user name: admin;
password: admin
CMS Management software” provided is able to acquire and parse the SMWR21A-
P sensor data with intuitive parameters and tracking path, which is great help for the
sensor operation.
Please contact supplier customer service for CMS SETUP(PC test software) and its
user manual. Installation and configuration of the software shall subject to the user
manual.
Test steps as follows:
① Test equipment required is shown as table 3-1：
Keep the convex groove outward and install the rubber ring into the network port
with the smaller hole outward and install the fixing rubber ring into the main body
of the waterproof connector.
After pulling the network cable without crystal head through main body of water-
proof connector, fixing rubber ring and fastening waterproof cover, make the
crystal connector of network cable and then insert it into the network cable.
Rotate the waterproof connector to lock it with network port and well connected.
Rotate the waterproof cover to lock with waterproof connector to make sure they
are firmly connected.

After power on, SMWR21A-P will generate sounds like“di” for two times and
“didi” after 30s, which means the radar sensors are ready to work. The radars also
supports PoE power supply.

●When radar alarm output is set and saved, power on the radar, and connect
the siren to radar, even if there is no PC server connection, the radar still works
to trigger the siren for intrusion protection.
Please correctly connect SMWR21A-P network cable with PC, and connect
12V DC, then bootup NSM Tools Management System User Manual
for IP configuration details(Help).
Strobe Siren Connection
Strobe siren signal wires are to connect to radar alarm signal output, as the
diagram 3-4:
Note：
● Radar alarm output is I/O relay type, please choose the right model & type
strobe siren.

● Only in rusion inside the drawn alarm zone can trigger the strobe siren.
● Only when alarm zone is set up, the strobe siren will work, if no alarm zone is set

No alarm output to
strobe siren
Solution
Refer to the above radar LED indicator light status to check the radar working
status. If it is abnormal, please report the problem description and LED status
to the engineer of the manufacturer;
Check if the buzzer gives off the sound “di” four times after power on. If not,
please check if the polarity of radar power cable is correctly connected to 12V
.CDDC. The rada orking current SMWR21A-P is about 650mA.
Make sure the radar is normally powered on and the radar is normally
activated, see above“No any response after power on”;
Use THE NSM Tools tool to search the radar to find out if the device IP has
been modified;
Check if the PC local add radar IP segment;
PC terminal ping radar IP, check whether can ping radar.
Please refer to chapter2.3 and check if radar installation direction is correct.
Use designated FMCW simulator to check if radar output is normal.
Please check if the radar installation position aims at the target area, which
may cause the radar to be disturbed by the surrounding objects:
Confirm if there is any vibration of pole where radar installed and check if GND
is normal.
Check if the alarm zone is drawn. ( When intrusion into the zone can trigger
alarming, target outside the zone can not trigger siren alarming.)
Check if the radar can cover the alarm zone in distance range.
●●
If two points above are correct, then use multi-functional meter to gauge the
two I/O signal output wires, by checking if it will sound alarming on the
buzzer mode.
When there is intrusion target in pre-set alarm zone, the radar is in well
condition if the meter sounds alarming. Then check the siren if it works or its
type not matching.
When there is intrusion target in pre-set alarm zone, the radar could has
issue if the meter does not sound any alarming.
