One master device can connect 3 node devices at most.
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.
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. Redundant identification spaces are needed on both sides of the detection line for the target detection. It ensures the stable recognition and tracking of the target before passing the detection line, which will make the detection and count more accurate.

Deployment Parameters

detect the current installation height automatically.
Note:

1. Ensure that there is no object directly below the device avoiding interfering the height detection.
2. The automatic detection of the installation height is not supported with dark floor/carpet (black, grey, etc.)
   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 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

and Feet Tracking.
Note:

1. Only Feet Tracking is supported when the working mode is multi-device stitching.
2. It is recommended to use heads tracking mode when the installation height is low in standalone working mode.

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.

Note:

1. Multi-Device Stitching cannot be performed between standard versions and high ceiling mount versions.
2. Multi-Device Stitching cannot be performed between VS133-P models and VS135-P models.

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.

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 Bind Node on Multi- Device List.
Manual: You can add a node device by the IP address, HTTP Port, Username or Password.
Note: Please ensure that the device you want to add is on the same local network as the master device and has low latency.
Auto: The device will use multicast protocol to 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.

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. This allows equipment splicing configuration without measurement.
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.

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.
