I. Introduction
Passenger flow products primarily comprise monocular and stereo vision cameras mostly top
mounted and angle mounted. Shape-wise, these cameras include F-type bullet cameras, E-type
bullet camera, E-type dome camera, and stereo vision eyeball cameras. Passenger flow products
are ideal for use in multiple indoor and outdoor scenarios, and provide people counting, region
people counting, linkage alarm, and statement generation functions. Passenger flow products are
widely used in banks, prisons, stores, tourist sites, and satisfy different business demands. This
document focuses on stereo vision passenger flow products.
Stereo Vision Passenger Flow Camera
Stereo vision passenger flow products can be top mounted or ceilings mounted, and are
mainly used for indoor passenger flow surveillance. The easy installation makes them the
preferred products in passenger flow count.

II. Site Survey and Type Selection
Overall Standard
1. The installation site must be bright enough, at least to ensure the head and shoulder contour of
people in the detection area is clear.
2. Avoid a complex scenario with frequently changing light, backlight, and direct light exposure;
3. People count is more accurate where people largely flow in one direction and the camera is
installed to directly face against the mainstream flow.
Top Mounting:
Install the product in such a way that the lens looks vertically down on the head and shoulders, and
the pedestrian direction is vertical to the rule lines. The head and shoulders of a person standing in
the center block the sight of his/her feet. A typical arming scenario is as follows:
Angle Mounting:
The camera directly faces the pedestrian direction that is vertical to the trigger lines. The horizontal
included angle is 30°. The following figure shows a typical arming scenario:

Passenger flow products are mostly installed at entrance and exit ceiling to monitor entrances and
exits. Here comes an issue: Some scenarios feature a high top door edge, blocking the line of sight
and affecting the detection rate. With this factor and the field of view (FOV) of the camera in mind, an
arming specification list is given as follows for reference:

1. The detection width is calculated on the basis of a 1.8 m tall person; persons falling within this
width can be effectively detected;
2. W is the effective detection width corresponding to the central axle of the camera. Do not mistake
it for the detection width of the farthest end or nearest end of the camera;

The optical axle of the camera lens form an 80-90° angle with the ground, and 2.5-3.8 m above the
ground.
Keep the underneath of the lens horizontal as much as possible for easy calibration and counting.

Angle-mounting instructions:
Figure 11 Angle mounting of (DH) IPC-HD4140X-3D-0210B
When angle-mounting the camera, make sure the optical axle of the camera lens forms an angle
with the horizontal plane from 30° to 70°, the larger the better in this range. Install the camera at
2.2-3.3 m; the higher the camera is installed, the bigger the angle with the horizontal plane,
facilitating passenger flow count. For more accurate device detection, see “Recommended
Installation Height”.

Precautions:
1. A camera with a 2.1 mm lens must not be installed less than 2.2 m above the ground; a camera
with a 2.8 mm focal length not less than 2.5 m; install an angle-mounted camera with a 30~70°
angle with the horizontal plane. See the specific installation illustration;
2. In a top-mounted camera, make sure the passenger flow direction is vertical to the line
connecting the two lenses of the camera (see the calibration illustration for details);
3. The ANPR (trigger lines) of the top-mounted camera shall be right under the camera; regarding
angle-mounting, adapt to the specific installation site in deciding where to place the ANPR;
4. The calibrated height or angle can differ from the actual height or angle; do several rounds of
calibration in this case to rule out occasional disturbance from the ground or lights. In calibration,
draw a large frame if possible to frame the ground inside. If abnormal data keeps coming up,
contact Dahua’s after-sales service;
5. Use this device where there is sufficient lighting;
6. Use this device indoor;
7. When using this device in a slightly dark environment, choose manual exposure and set the
exposure time to 0-10 ms;

III. Configuring Images
The monocular passenger flow system comprises traditional bullet cameras and can also be
used as a traditional camera system for surveillance. In outdoor and angle-mounting applications
where the monocular passenger flow system is installed, you likely have to handle backlight and low
luminance scenarios, so an additional section is dedicated to image adjustment in this situation.
Stereo vision passenger flow devices typically need not adjust the image effect.
1. Upgrade to the latest general program before configuration. On GDP (gdp.dahuatech.com),
choose the correct Program Type according to model numbers: Baseline, general patches, and
then download the latest programs.
2. Set up different parameters for different scenarios in configuration. Some scenarios need two
configuration plans to show the effect. In this case, switch between the configurations by time. See
the following figure:
3. Like traditional cameras, angle-mounting passenger flow cameras can be used for surveillance.
To this end, adjust the image quality. The default settings are enough to handle common scenarios;
Adjust the Exposure first. See the following figure:
Adjust the Picture parameters for more refined details.

DH Network Camera
Product Construction Instruction Manual (Passenger Flow Solution)
17
4. Adjusting the overall color: The overall cast can switch to the white balance mode, which can be
done with the Outdoor or Road Lamp settings.
5. In a backlight scenario, enable Backlight WDR to adjust the picture quality.

IV. Function Config
8341 Stereo Vision Camera
The system counts the passenger flow into and out of the detected region. When the counted
passenger flow exceeds the preset alarm-triggered quantity, an alarm is triggered, followed by linked
settings.
1. Enable Smart Plan
The passenger flow function of the device becomes effective only after the smart plan is enabled.
Step 1 Select Setup > Event > Smart Plan.
The Smart Plan interface is displayed. See Figure 3-1.
Figure 3-1 Smart plan
Click the selected smart plan.
Click Save to complete the configurations.
2. People Counting
The system provides two counting methods: Region people counting, people counting.
Region People Counting
Use Region People Counting to set up a closed region. The system counts the passenger flow
into and out of the region. When the counted passenger flow exceeds the preset alarm-triggered
quantity, an alarm is triggered.
Select Setup > Event > People Counting.
The People Counting interface is displayed. See Figure 3-2.

DH Network Camera
Product Construction Instruction Manual (Passenger Flow Solution)

Figure 3-2 People counting (1)
Set the Rule to Region People Counting.
Select Enable to turn on region people counting.
Click Draw Area to draw the detected area in the surveillance image.
For passenger flow and region people counting, drawing one closed area is enough. The
difference is that an additional direction shall be drawn when counting passenger flow to
differentiate the entry and exit directions.
When drawing the rule direction for passenger flow counting, draft the trigger line from left
to right, with the direction pointing downward.
When drawing the rule direction for passenger flow counting, draft the trigger line from right
to left, with the direction pointing upward.
Draw the trigger line in the image center.
Where only one device is mounted: The length of the drawn trigger line must exceed the
width of the passage.
Where multiple devices are mounted: The drawing of trigger lines cannot circumvent the
coinciding areas of different cameras. Based on actual count data, draft the length of trigger
lines of adjacent cameras to circumvent these coinciding areas as much as possible.
Set up the people counting parameter. See 图1-1Table 3-1
