Chapter 1. Brief introduction

DS-2CD6825G0/C-I(V)(S), dual-lens camera, based on the binocular stereo vision technology, adopting

3D head detection and 3D tracking, can obtain accurate real-time trajectory of all moving objects within

the monitoring scope, analyze the trajectory data and achieve high-precision people counting. It is very

suitable for places where people counting is needed, such as shopping mall, supermarket, chain store, the

scenic spot, subway station, bus station, exhibition hall, etc. Meanwhile together with iVMS-4200, platform

or server, solutions with comprehensive data analysis and query system can also be established.

Chapter 2. Installation specification

2.1 Focal length and counting width

The counting width depends on the installation height. The recommended installation height for dual-lens

camera is less than 6.0m (19.7ft). The specific corresponding relation shown below:

2.3 Installation steps

Please pay great attention to the mounting position. Inappropriate mounting position may cause loss

of accuracy. The recommended mounting position is shown below:

Horizontal sketch map of mounting position

Vertical sketch map of mounting position

Effect picture after installation

Keep “HIKVISION” logo in the same direction as the “Front” arrow, see picture below:

“Front” arrow and “HIKVISION” logo

Make sure camera mounted vertically above the passenger flow(90°vertical by the ground), see

picture below:

Passenger flow（perpendicular to the door）

For some scenarios where there are multiple cameras, mount the cameras according to two

rules.

Rule one: If there are turnstiles, each camera should be mounted to monitor certain turnstile

Rule two: If there is no turnstile, at first, mount the cameras in one line, and make sure the

cameras have the same focal length. Then, keep a proper distance between each camera

according to the overlap (see the yellow area below) of the adjacent two cameras’ counting

width. The suggested overlapping length is between 0.2-0.5m.

Notice

1) People flow should be in vertical up-and-down direction

Passenger flow in horizontal direction (wrong)

Passenger flow in slant direction (wrong)
