3. Power Supply
VS133-P can be powered by 802.3at PoE+. Choose one of the following methods to power up
the device.
Powered by a PoE Switch
Powered by a PoE Injector
4. Access the Sensor
VS133-P sensor provides user-friendly web GUI for configuration and users can access it via
Ethernet port. The recommended browsers are Chrome and Microsoft Edge. The default IP of
Ethernet port is 192.168.5.220 (can be found on the device label).
Step 1: Power on the device and connect the Ethernet port to a PC.
Step 2: Change the IP address of computer to 192.168.5.0 segment as below:
a. Go to StartControl PanelNetwork and Internet Network and Sharing
CenterEthernetPropertiesInternet Protocol Version 4 (TCP/IPv4).

8
b. Enter an IP address that in the same segment with sensor ( e.g. 192.168.5.61, but
please note that this IP address shall not conflict with the IP address on the existing
network);
Step 3: Open the Browser and type 192.168.5.220 to access the web GUI.
Step 4: Select the language.
Step 5: Users need to set the password and three security questions when using the sensor for
the first time (three questions can be skipped by refreshing webpage). After configuration, log in
with username (admin) and custom password.
Note:
1) Password must be 8 to 16 characters long, which contains at least two kinds or more in
combination with numbers, lowercase letters, uppercase letters and special characters .
2) You can click the “forgot password” in login page to reset the password by answering three
security questions when you forget the password if you set the security questions in advance.

5. Operation Guide
5.1 Dashboard
After logging on to the device web GUI successfully, user is allowed to view live video as follows.

10
Parameters
Description
Reset Count
Clear all accumulated entrance and exit people counting values.
Output
Click to output a 5s high level signal from alarm out interface.
Alarm Output: dry contact, output=two contacts closure
Track
When enabled, there is tracking line when people pass the detection area.
Note: When working mode is Node mode, the device will not show people counting data.
5.2 Rule
VS133-P supports 3 working modes:
Standalone Mode: works as a standalone device to count people.
Master Mode: works as a master device to receive live view and tracks from other node devices.
One master device can connect 3 node devices at most.

11
Node Mode: works as a node device to forward live view and tracks to the master device.
5.2.1 Basic Counting Settings
Draw Detection Lines
Users can draw detection lines to record the people count values which indicate the number of
people enter or exit.
Step 1: Click Draw Detection Lines.
Step 2: Left-click to start drawing and drag the mouse to draw a line, left-click again to continue
drawing a different direction edge, and right-click the mouse to complete the drawing. The line
can be dragged to adjust the location and length. One device supports at most 4 broken lines
with maximum 4 segments each.
Step 3: If users need to delete the line, click Draw Detection Lines and select the line which need
to be deleted, then click Clear This Line or click Clear All.
Note:
1) The arrow direction of the detection line depends on your drawing direction.

12
2) Ensure that the detected target can pass through the detection line completely. It’s
recommended that the detection line is perpendicular to the In/Out direction and on the center
of the detection area without other objects around.
3) A redundant identification area needed to be left on both sides of the detection line for the
target. This is to ensure that the sensor has stable recognition and tracking of this target before
it passes the detection line, which will make the detection and count more accurate.
Deployment Parameters
Parameters
Description
Installation Height
Set the device installation height. Click Detect to detect the current installation
height automatically.
Note: Dark floor/carpet (black, grey, etc.) does not support to detect the
installation height automatically.
Max Target Height
Set the maximum target height, then the device will ignore the objects higher
than this setting value.
Min Target Height
Set the minimum target height, then the device will ignore the object shorter
than this setting value.
Child Filter Height
Set the max child height when children distinction feature is enabled.
Note: Due to the error in ToF distance measurement (0.035 m), the Max. Target Height should be
set as maximum pedestrian height plus 0.035 m and the Min. Target Height as minimal
pedestrian height minus 0.035 m in the actual applications. For example, if the pedestrian height

13
is 1.6 m to 1.8 m, the Max. and Min. Target Height should be configured as 1.835 m and 1.565 m
respectively.
Counting Strategy
Parameters
Description
U-turns Filtering
When enabled, it allows to draw an area for every line and the device will
count the In and Out values only when people passed this area. Users can
left-click to start the drawing and add edges for this area, then right-click to
stop drawing.
Children
Distinction
The device will detect the people shorter than child filter height as children.
Staff Detection
The device will detect the people who wear reflective stripes as staff tags on
the visible parts (neck, shoulders, etc.) as staffs.
Reflective stripe requirements: width > 2cm, 500 cd/lux.m2
Input Enable
Count Externally
Only when alarm input status is the same as the preset trigger status, will
the device count the data.
Alarm Input: dry contact, low level=two contacts disconnected, high level=two
contacts closure
Report Strategy

14
Parameters
Description
Trigger Report
Report the people counting data immediately when the in/out value changes.
Periodic Report
Report the people counting data periodically.
Period
Set the period of reporting periodic report.
Range: 1-1080 mins, default: 10 mins
5.2.2 Multi-Device Stitching
Multi-device stitching is mainly used to monitor a larger detection area than just the area
covered by a single device. When using this feature, devices should be installed next to each
other and ensure the detection areas tangent or overlapping. It only uses one master device to
output total counting data.
Before using this feature, set one device as Master Mode and other devices as Node Mode.
Note:
1) Ensure the head of one person can be seen on both live views at the same time.
2) The devices can also be installed without overlapping as required.

15
Device Positioning
Device positioning is done via X&Y coordinates. For example, the installation direction of the
master device is shown as below. When the master device’s coordinate is (0, 0), the coordinates
of the node devices are all positive values.
Add Node Devices
Step 1: Go to the master device web GUI, then click BindNode on Multi-Device List. The device
will search for the unbound node devices under the same local network.
Step 2: Select the node device and type the login password of the node device.
Step 3: Fill in the installation height of a node device and relative position information if these
parameters are already measured. If not, save default settings and skip to Step 4.

16
Step 4: Select the node device on the Mult-Device List, click Adjust Relative Position.
Drag the live view of node device to adjust the location and angle, and the relative position
parameters will change automatically as your operations. Besides, users can also adjust the size
of this live view.
Tips: cut the staff tags or other reflective stripes into pieces and stick them to the ground of
overlapping areas, then drag the live view of node devices to make highlight markers in the two
live views overlap.
Step 5: Click Set & Testing Track, then check if the tracking lines are connected and smooth
when people pass on the live views of multiple devices. If not, click Stop Testing to adjust the
node device’s live view location slightly.

17
Step 6: When all settings are completed, users can draw detection lines and even U-turn areas
on the new stitching live view the same as standalone mode devices.
Step 7: Click Unbind to disconnect the node device if necessary.
