3 Product Introduction

4 People Counting People counting is used to calculate the number of people entered/ left/ passed by a certain configured area and figure out daily/ weekly/ monthly/ annual reports for analysis.

5 Application Scenarios Supermarket Chain Stores Shopping Mall Station Museum Scenic Area

6 People Counting IPC ids-2cd6810f/c (2mm) ids-2cd6810f/c (2.8mm) 1/3 Progressive Scan CMOS 2 mm/2.8 mm lens, optional 3D digital noise reduction DC 12V / PoE Resolution 640*480 Black/White view

7 Key Feature

8 Overview Hikvision dual-lens people is a self-developed technology that is mainly based on binocular stereo vision and aims at providing the people counting solution to the commercial industries. Advantages: More accurate, exceeds 97% Easier configuration Better anti-interference ability Small & compact, only 3.5cm thickness

9 Dual Lens 3D Image Dual lens image combination Every object in the image has X, Y and Z axes coordinates. The Z-axis coordinate represents height, which prevents the interference from other objects

10 Good Anti-Interference Ability Shadow or other objects will not cause miscounting Camera can identify two person as long as there is space between two heads

11 Height Filtering Based on the height information in the 3D axis, the target height should be in the range of the human height, thus filtering the interference of the cart, baby carriage, etc.

12 Loitering Filtering The camera can focus on a target and track it until it disappears in the image, thus effectively filtering the repeated count of the loitering target.

13 Built-in Flash Storage Time Max. 416 days Advantage Convenient No need micro SD card for people counting

14 ANR Local Monitoring Data is stored in Flash Built-in Flash Upload counting data Theory Data is stored in Flash and NVR Advantage When the network is disconnected, the counting data will be stored in flash. Camera will upload the data to NVR once the network is re-connected. Make sure the data is kept and stored.

15 Flexible Statistics Daily, weekly, monthly, annual data (people entered/ exited/ passed by) can be showed as table, bar or line chart. Table chart can be exported as excel file.

16 Installation & Configuration

17 Installation Recommendation How to choose a right position? The camera should be installed in the middle of entrance door. Also it is recommended that the camera s position should be as closed as possible to target entrance door without any obstacles. The lens should be installed 90 vertical by the ground.

18 Installation Recommendation How to define the camera number? The number of cameras should be increased if: - There are obstacles or more than one doors in the scenario. - The target door is wider than camera s effective coverage. * camera s effective coverage is limited by the following graph instead of camera s physical FoV.

20 Installation Recommendation Height (m) Recommended Focal Length (mm) Width of Door (m)

21 Installation Recommendation

22 Configuration People entering and exiting red area causes one person adding, the hovering people are filtered; Yellow arrow is people entrance direction; In manual calibration, we need set the height of camera In auto calibration, we need draw a green square aimed at any area of the flat floor for calibration 1 Entrance arrow (yellow) 2 Detection Area (red) 3 Calibration Area (green)

23 Configuration Auto Calibration Note (green) Choose the calibration area with rich texture and plat ground; The brightness of calibration area should be uniform, no area with exposure or reflect light; Choose the area in the center but not the edge of the image; If the ground area size is less than 25% of the whole image, please use manual calibration

24 Configuration Real-Time Upload Data : Data uploads to NVR/software once people enters or exits Data Statistics Cycle : Data uploads to Flash and NVR/software by a specific interval Data Statistics Cycle : 1 min to 60 min We can set min. height to filter some objects like cart or baby carriage
