Operating Instructions HUZ3 4 / 4

1. Introduction

Publicount is a contact-free people counting system based on radar technology to

determine customer traffic in a shopping centre or in certain areas of a shopping

centre.

To do this, sensors are installed above the relevant access points. These send

physical measurement data to a data-logger, also called sensor management centre

or SMCs, also installed in the entrance area.

The SMC evaluates the numbers of people entering and leaving and assigns the

people counts to the time of day. Customer traffic data are stored in the SMC for the

last 30 days.

A number of these SMCs are linked to a PC which stores customer traffic data on a

long-term basis and allows further processing in graphic or tabular form.

These operating instructions contain information on

- assembly of the counting equipment (positioning and cabling of the SMCs

and sensors)

- configuration of the counting equipment (operation of all firmware versions)

- firmware updates for the counting equipment (SMCs and sensors).

Warning: Failure to follow the guidelines for the assembly and cabling of

sensors/SMCs described in these operating instructions may

result in damage to the equipment!

2. Sensor installation

2. Assembly of sensors

This chapter describes how the sensors have to be projected (location of projection

fields, number of sensors to be installed) and how the sensors are connected to the

SMC (connector assignment).

The sensors are integrated into the ceiling or into cable channels or suspended

directly from the ceiling.

Warning: Sensor mountings must be insulated for correct operation. The

sensor should not have any contact with other electrical power

circuits, e.g. the earth circuit. Failure to comply with this

instruction may result in damage to the sensor.

2.1. The size of the projection field

It should be noted that these parameters do not represent definite lines (the

projection field is simply weaker here).

Note:

The parameters given above refer to an intensity drop of 3 dB. The following angles

apply for other intensity levels:

2. Sensor installation

2.2. Number of sensors to be installed

The number of sensors to be installed depends on the firmware version of SMC

used.

2.2.1. SMC Firmware 1.x

The number of sensors to be installed depends on the installation height and the

width of the section to be covered.

The distance between the sensors is installation height / 3. The distance between

the wall and the outside sensors is installation height / 6.

Operating Instructions HUZ3 8 / 8

2. Sensor installation

2.3. Position of the projection field

For correct operation, the sensors must be projected in such a way that

• there are no moving parts within the sensor field, such as:

o entrance doors which swing through the sensor field

exception: glass doors without metal gridding

o escalators, fans

• there are no people present in the sensor field for long periods, e.g.

o if there are goods located within the sensor field which the customer

walks around a number of times and so is counted more than once

o if queues form here.

• the construction on which the sensors are mounted is vibration-free.

In addition the following points must be taken into account with respect to the position

of the projection field:

• If the projection field lies too far inside the shop there is the likelihood that

people will remain within the projection field for a considerably longer time

(they come in and then think first of all about where they want to go / goods

displays in the vicinity of the entrance area / ...).

• If the projection field lies too far out it is possible for people to be counted who

have not entered the shop (looking in from outside and then going away again

/ walking outside along the line of the sensor field / ...)

• If the entire entrance area is not covered, then people can walk in such a way

that they do not cross the counting area (see Fig. 2.3-1)

• The projection field should not be directed at metal flooring elements (if the

store is in the construction phase, mats can be used which do not contain any

metals)

Getting the projection right is crucial for later adjustment. If the projection is poorly set

up, a counting accuracy of 95% can only be achieved with a very great deal of

adjustment, or possibly not at all.

If the client wishes the sensors to be positioned differently (e.g. for optical

reasons), it must be pointed out that this means that a counting accuracy of

95% can no longer be guaranteed.

A few examples of the position of the projection field are given on the next page.

2. Sensor installation

The following illustration shows the entrance of a store (the dark rectangles represent

the wall where the entrance ends). For counting to be correct, the projection fields

must be arranged to that their centre line covers the entire entrance area.

Fig. 2.3-1 Position of projection fields at the entrance

All sensors in this entrance area are to be given the same entrance number in the

configuration assignment (e.g. all entrance 1).

In the following illustration, the entire entrance area is not covered, which means that

people can walk in such a way that they do not cross the counting area.

If the entrance is divided by a pillar, for example, as shown in the following

illustration, then the sensors are assigned to the different entrances.
