Multi-Device Stitching

Overview

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 are tangent or overlapping.

Note:

Ensure the head of one person can be seen on both live views at the same time.
The devices can also be installed without overlapping.
Device positioning is done via X&Y coordinates. For example, the installation direction of the master device is shown as below, the logo needs to be facing the front. When the master device’s coordinate is (0, 0), the coordinates of the node devices are all positive values.

Before using this feature, set one device as Master Mode and other devices as Node Mode.

Master Mode: Receive target tracks and view from the device, responsible for all counts, rule setting, data push and other functions.
Node Mode: Only extends the view of the master device.

Node Device Setting

Step 1: change the WLAN IP Address of node devices to different subnets from master device’s WLAN IP address. If the master device is a PoE version device, skip this step.

Step 2: Select work mode as Node and wait for the device to reboot.

Step 3: Find the Wi-Fi access point of master device and connect.


Parameters	Description
Connection Status	Show the connection status between the node device and master device.
Master Device IP Address	Show master device’s IP address. When this IP address is under the same network with the node device, the node device can be bind to the master device.
Master Device SN	Show the master device’s serial number.
Master Device Name	Show master device name.
Unbind Master Device	Click Unbind to release the connection status, this device will be deleted from the list of the master device.

Master Device Setting

Step 1: When work mode is on Standalone or Node mode, select the WLAN channel to an idle channel. Users can use test App (like Wi-Fi Analyzer) to check ideal WLAN channels to reduce interference.

Note: The scene preview and people counting results are dependent on the WLAN channel selection, also the distance between node devices and master device. Please adjust the distance to ensure accurate scene preview or counting results.


WLAN Channel	Video Stream	Static Image/No Image	Counting Inaccuracy
Occupied Channel	Not Support	≤ 6.5m	> 6.5m
Idle Channel	≤8m	≤10m	>10m

Step 2: Select Master as the working mode and wait for the device to reboot.

Step 3: Go to the master device web GUI, then click Bind Node in the Multi-Device List. The device will use multicast protocol to search for the unbound node devices under the same local network.

Step 4: Select the node device and type the login password of the node device.

Step 5: 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 6.

Step 6: Select the node device on the Multi-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.

Tip: 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 7: 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 8: 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 9: Click Unbind to disconnect the node device if necessary.
