3. Power Supply
VS135 can be powered by power adapter (12V DC, 2A).
4. Access the Sensor
VS135 provides user-friendly web GUI for configuration access via Wi-Fi. Users need to customize the password when using the device for the first time. The default settings are as below: Wi-Fi SSID: People Counter_xxxxxx (can be found on the device label) Wi-Fi IP: 192.168.1.1 Here are the wireless method way of accessing the web GUI: Step 1: Enable the Wireless Network Connection on your computer, search for corresponding Wi-Fi SSID to connect it, then type 192.168.1.1 to access the web GUI. Step 2: Select the language. Step 3: 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 .

5.2 Rule

Basic Counting Settings
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. Step3: 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. If users need to
flip the line, select the line which need to be flipped and click Flip Arrow Direction. And users can click Flip All to flip all detection lines.

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.

Reset Cumulative Count on Schedule Periodic Report
Period

Enable to periodically reset cumulative count on schedule. Cumulative Count includes: Total In/Out counting of each detection line. Max./Avg. Dwell Time of each detection region. Report the people counting data periodically. Set the period of reporting periodic report. Range: 1-1080 mins, default: 10 mins

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 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.

6.1 Installation Height
The maximum installation height is 3.5 m and the minimum installation height is hmax+d+d. For example, when the maximum pedestrian height is 1.8 m, then the minimum installation height is 1.8+0.5+0.035=2.335 m.
The maximum installation height is 6.5 m and the minimum installation height is hmax+d+d. For example, when the maximum pedestrian height is 1.8 m, then the minimum installation height is 1.8+2+0.035=3.835 m.

6.2 Covered Detection Area
The detection area covered by the device is related to the field of view angle of the device, the installation height and the target height. The length of the detection area is approximately x=1.155×(H-hmin) and the width of the detection area is approximately y=0.828x (H-hmin).

For example, if the Minimum height of pedestrians is 1.7 m, the detection area corresponding to each installation height is as follows:

6.3 Environment Requirements
Dark floor/carpet (black, grey, etc.) will affect the device to count staffs when Staff Detection is enabled.

Avoid 940nm light which may result in incorrect counting. Outdoor sunlight shining on the over channel will not have any effect, but the mirrored
reflections that allow sunlight to shine on the ToF Sensor should be avoided. When the carpet/floor is black, ensure there is no obstacle within a 60cm hemisphere range
in the direction of the device. Otherwise, the device imaging may appear abnormally red.
6.4 Installation
Ceiling Mount
Installation condition: ceiling thickness > 30mm. Step 1: Take down the side covers.
Step 2: Fix wall plugs into ceiling holes.
27

Step 3: Remove rubber plugs on the rubber sleeve, connect all required wires.
Note: Remove the rubber sleeve if waterproof is not required for easy installation. Use round wires. Ensure the rubber sleeve and the bottom cover are tightly connected without a gap if
waterproof is required; if necessary, wrap the waterproof tapes around the wires to avoid any gap. Tighten the wires to avoid contact with internal modules. Step 4: Fix the device to ceiling with mounting screws.
Step 5: Restore side covers.
28

Ceiling/Lintel Mount (with Optional VB01 Multifunctional Bracket)
Step 1: Fix the pole to the device with the hole on the device. Step 2: Adjust the length of the pole, then adjust the direction of 3-axis ball and tighten it with the handle. Step 3: Determine the mounting location and drill 3 holes, fix the wall plugs into the mounting holes, then fix the bracket base to the wall plugs via mounting screws. (Note: If the wire needs to be extended to the interior of the ceiling or wall, a wire hole with a suitable size is also required to be drilled.)
Step 4: Remove the cover on the device, and then connect all required wires and pass them through the inside of pole. Step 5: Fix the pole to bracket base with screws and nuts. Ceiling Mount
Lintel Mount
29

Installation Note: Ensure that the ToF sensor is facing down and the tilt angle from the ground is no greater
than 15° for the standard version, and no greater than 10° for the high ceiling mount version. Avoid direct Infrared LED light in the detection area. Not suggested to install the sensor close to glass or mirror. Ensure that there are no other objects blocking the ToF light within a 50cm radius of the
device's field of view. Though the device is compliant with Class 1 (IEC/EN 60825-1:2014), please DO NOT look at
the ToF sensor too close and directly. Avoid installing the device against the wall and ensure the device keeps away from the wall
with a distance of at least 40cm. When you install devices on the top of swinging doors, it is suggested to keep the door
normally open. If the door must be normally closed, please install the device on the other side of the door to keep away from the door's movement. And it is suggested to keep away from the door with a distance of at least 40cm.

6.5 Factors Affecting Accuracy
Wearing a fisherman's hat or carrying a cardboard box on the shoulder: The target will not be recognized because it will become unlike a human in depth map.
Handheld or cart-carrying a humanoid doll with sufficient height to pass by: The doll will be mistakenly detected as people because it is human-like in depth map.
