Facing the pandemic outbreak of coronavirus, many governments imposed social distancing
methods to reduce the risk of contraction. One method is to control the number of visitors inside
a building while allowing people to work or purchase the necessities. Using the 3D people
counting cameras at the entrance and exit of a facility, the current occupancy number can be
displayed at the store front.
You can configure an occupancy limit and display the message when the limit is reached.
Instead of having a secuirty personnel to count the number, the solution can help control the
customer trafc.

The solution enables the following:
• Accurate counting of people entering or leaving a facility.
• Displays the occupancy number on an HDMI monitor.
• Business owners can transfer the solution into VIVOCloud Retail solution when social
distancing becomes unnecessary.
• Notication to cell phone app via the VIVOCloud utility.

Deployment:
If the need should arise, multiple counting cameras can be stitched together to cover a
wide entrance. The calculated data is polled from the Master camera.
A facility may have separate entrance and exit.

A sample conguration of 2 cameras mounted on an entrance and an exit is shown below.
Each camera covers a owpath indicating the IN and OUT directions.
When any person passes the owpath, an IN or OUT count occurs. When both cameras
are added to the NVR conguration, their IN/OUT counts will be combined, and the nal
result displays on the screen via the HDMI connection.

Swing door
If installed on top of a sliding door, the camera can be mounted directly above the door
frame.
If installed on top of a swing door, the camera should be mounted on the ceiling inside
the the door, and with a distance to the door. Its detection coverage should cover the area
inside the door.

Considerations
Note the following when planning the camera installation:
1. The installation site must be adequately lighted for optimal accuracy with video analysis.
2. It is preferred that the camera is mounted directly above the objects to be counted. Use
tools such as a spirit level to ensure the camera is installed level.

3. The receommended installtion position is 2.4m ~ 3.6m. Higher position is also allowed.
For positions higher than 3.6m, you can also use the Zoom-in mode operation.
3-1. Use a spirit level to ensure the camera is installed level.
3-2. Use a laser distance meter to measure the installation height. The height
information MUST BE correctly measured and entered in the camera's conguration
page.
3-3. Please delete the height of the camera canister, e.g., 250cm (ceiling height) -4cm
(the height of camera canister) = 246cm. The reason for doing so is because the
lenses are at the lower edge of the canister.

The following applies when stitching multiple SC8131 cameras:
1. The Stitching conguration takes place on the Master camera. 1 Master camera with
up to 6 Slave cameras can form a stitiching conguration.
2. All Master and Slave cameras in a Stitching conguration should be running the same
rmware.
3. The physical positions of cameras should be consistent with the stitching order. It is
recommended you keep a note of all cameras' positions and IP addresses. Static IP
addresses are prefereed.
4. Select a camera on the edge of the line as the Master camera.
5. Recruit the Slave cameras via a web console to the Master camera.
6. When software conguration is done, it is best to have human trafc in and through the
coverage areas of these cameras. If there are no trafc when you congure the Stitching
conguration, you should have someone walking in the overlapped areas.
The peer cameras then automatically calculate the coordinations of the same moving
objects that appear in the overlapped FOVs between them. The walking should persist
for at least 2 minutes.

• The cameras here are shown on their long side.
• The FOV is the camera's "detecting area."
7. Once the Stitching conguration is done, the positioning order of peer cameras will be
xed, and you cannot change their Stitching order unless you unstitch them.
9. The tracked objects will appear on the live view of a stitched conguration after a
3-seconds delay, due to the network transfer and processing time.
10. It is best that all cameras in a Stitching conguration are installed at the same height
and with the same tilt angle (if applied).

Consider the following when stitching multiple cameras to form a large virtual oor plan:
8. The maximum distance between cameras, when mounted at a height of 300cm, is
278cm (from edge to edge). The FOVs of two cameras must overlap to a certain amount
in order to cover people walking between them. An estimation of a man of 185cm tall is
applied here.
