2. How the People Counter Works
The counter looks down on the area where people are to be
counted.
As people walk underneath the counter they are detected
and tracked.
3. How the People Counter Works
The counters field of view is, effectively, a square on the
ground.
Think of it as a three dimensional pyramid stretching from
the ceiling to the floor.
4. How the People Counter Works
As people walk underneath the counter, their
body heat is detected as infrared radiation.
Once detected the source of infrared
is tracked around the field of view
and is counted if it crosses either of
the two (by default)
virtual count lines
(configured at time of
install).
5. Dual View Counter
The dual view counter model provides an additional
video view alongside the thermal view.
This allows for:
•
•
Remote setup and diagnostics
Counter performance monitoring and validation
services
6. How the People Counter Works
Multiple counters can be connected together, if
required, in order to count through a very wide
entrance:
•
One IP master can be installed with up to
seven node units, to form a ‘Wide Opening
Network’ of 8 Units.
•
One IP dual view master can be installed
with two node units, to form a ‘Wide
Opening Network’ of 3 Units.
8. Mounting Locations
Things to look for:
•
The counter should be positioned above where people
walk and away from areas where people queue
or stop
20°
Outdoor
•
The counter needs a clear view of the area
Version
Only
beneath so position away from obstacles and
signage hanging underneath
•
Three lens versions of the counter
are available dependant on
ceiling/mounting height
60°
40°
10. Mounting Locations
For most standard double door entrances, a single unit will
usually be enough.
Front
View
A single counter should be positioned centrally to the door,
so that the field of view extends to the left and right side of
the door.
11. Mounting Locations
To confirm that a single unit is enough, measure the height
of the ceiling and width of the door.
W
H
Front

And look up the information on the mounting height graph
(Irisys document IPU40188).
12. Mounting Height Graph (m)

16. Mounting Locations - Examples
Do Not Position Counter Too far away from the Door as
people could be missed if they turn left or right:
Overhead View
Side View
17. Mounting Locations - Examples
Do not position counter too close to the door as some of
the field of view will be blocked and unusable - the
counter will also not ‘see’ through the glass:
Overhead View
Side View
18. Mounting Locations - Examples
In any case, the counter should not be positioned
directly above the swing of a door:
Overhead View
Side View
19. Mounting Locations - Examples
And should not be mounted between the two doors of a
double door:
Overhead View
Side View
20. Mounting Locations - Examples
Instead mount the Counter outside the swing of a door:
Overhead View
Side View
21. Mounting Locations - Examples
And away from the swing of a double door:
Overhead View

22. Mounting Locations - OPTIMUM
The optimum position for the Counter is where the field
of view meets the ‘door line’:
Overhead View

23. Mounting Locations - OPTIMUM
Optimal position is central to door, approximately half the
field of view away from the door:
½ FOV

24. Mounting Locations - Examples
But, if the door is fully open and is undercover, e.g. a
shop in a mall, the units can be positioned closer to the
lease line if required – but do not block out any of the
FOV:

30. Mounting Locations - Corridors
In Corridor-like locations the counter should be mounted
away from areas that might cause people to stop in the
middle of the field of view. Avoid:
•
Chairs, sofas, and other waiting areas
•
Side doors
•
Filing cabinets, water-coolers, coffee machines, pay
phones, or anywhere that a person could stop

31. Mounting Locations - Elevators
For counting at Elevators, correct counter placement on
the ceiling is crucial:
Elevator Shaft
X
For 60° units:
X = Tan (60 / 2) h

Or
X = 0.577 h
Elevator
Counter should ‘see’
Under the Wall and
Through Elevator
Doors (when open)
Side View
32. Mounting Locations - Elevators
When using 40 degree units at Elevators, correct counter
placement on the ceiling is even more critical:

Or
X = 0.364 h
Elevator
Counter should ‘see’

33. Mounting Locations - Elevators
When counting at Elevators, each separate Elevator
should have its own counter, mounted centrally to the
door. Do not worry if their field of views overlap:
Overhead View
34. Mounting Locations – Elevators
In most cases, counting at the approach to the elevator
rather than directly through the elevator doors, will be
the preferred method, if possible.
This will be more accurate in the majority of cases. E.g.:

35. Mounting Locations – Elevator Lobbies
Counting IN and OUT of an elevator lobby will be more
accurate than counting IN and OUT of the elevator:

36. Mounting Locations – Escalators/Stairs
Counting directly over stairs or escalators is not
recommended. Instead count at the very top or bottom:

37. Mounting Locations - Stairs
Alternatively, count at a ‘landing’ point on stairs, if
possible:

of escalators:
•
These can create
thermal reflections
which can mask
genuine targets

39. Outdoor Installations
For outdoor installations - even when undercover – the
outdoor variant counter should be used:
•
•
Outdoor counters are designed to resist water
penetration from the weather
They also have a breather valve in order to prevent
damage from condensation build up
40. Counter Base Installation
•
Ensure Base is level to the ground
- Remember that the ceiling may not be
- Pack under the base if required
•
Pay attention to the orientation of the Base,
always point arrow into the store
•
Secure base to the ceiling using
mounting holes provided with
appropriate fixings
•
Once the base is correctly aligned lock
in place using this screw position

PoE Voltage levels will destroy an Irisys IP counter!
As part of the 802.3af (PoE) specification:
•
PoE switches should not supply voltage to a non-PoE
device
•
PoE switches should provide isolation between all
cable connections and ground
Many switches claim to be 802.3af compliant – but are NOT

49. PoE Warning
A fully and completely 802.3af compliant PoE switch will
work fine with Irisys counters.
•
•
Unfortunately there is no easy way to identify a non
compliant switch
A non compliant switch may blow the counter
immediately, or after a couple of hours
The only way to protect against a non compliant PoE
switch is to utilise an Irisys Power Injector
•
The input and output are fully isolated so PoE voltage
cannot go through, and on, to destroy the counter
50. Cable Connections
Power Injector (IWC3060) is intended to be installed in
the patch panel cabinet:
Structured cabling
100m (330ft) Max IP cable length
51. Cable Connections
Power Injectors have four ports and so can provide power
to up to four different locations:
100m (330ft) Max IP cable length
52. Battery Backup
Insert the included battery into the IP masters battery
holder:
•
•
•
Check correct polarity!
Battery is required for correct date and time during
power failures
(Not required on node units)
The battery may not be required, as long as the data
retrieval software time syncs at every data poll and also
reconciles any out of sequence data records
54. Wide Opening Networks
For wider doorways, a ‘Wide Opening Network’ must be
used.
W
H
To calculate the number of units required, the mounting
height graph is used again (Irisys document IPU40188).
55. Wide Opening Networks
To prevent people being missed, the field of view of all the
counters on a Wide Opening Network, must overlap:
As part of the configuration stage all units positions are
checked to verify that there is a sufficient overlap.

81. Disjointed Wide Opening Networks
The normal use of a wide opening is to fully cover a wide
entrance which a single unit could not cover by itself:
But also a wide opening network can be utilised to cover
multiple doors which are close to each other, but not close
enough for units to overlap:
82. Disjointed Wide Opening Networks
The advantages:
•
•
•
•
Only one IP connection required
Simple cabling – star wiring to each doorway NOT
required
Up to eight units = up to eight doors covered
Count Logs from all doors covered are retrieved
from one master unit
Disadvantages:
•
•
The more doors covered, (potentially) the less
storage space available for count logging
If master goes down, all doors ‘go down’

Each counter must be configured with a number of
settings:
•
•
•
•
•
Usual configuration is via IP connection through an
Internet Browser
Browser must support Microsoft SilverLight add-on, e.g.
Internet Explorer
Setup Tool is served as web pages to Internet browser
All settings made are stored in counters Flash memory
(Alternative configuration is via serial)
92. IRISYS People Counter Setup Software
If connecting via IP:
•
•
•
•
•
Ensure laptop is on the same IP range as the IP master
IP Master default IP address is 192.168.0.10
Internet Explorer is preferred browser
Also compatible with Firefox, Safari & Google Chrome
Simply enter IP address in address bar:
93. IRISYS People Counter Setup Software
You will need to login to the counter.
Default Login Details are:
•
•
Username: admin
Password: installer
96. IRISYS People Counter Setup Software
Settings will be applied:
The redirect will most likely fail until you change your
laptop IP address to the same range as the counters new
IP address.
Reconnect to the counter.
97. IRISYS People Counter Setup Software
Ensure Client Connection Mode is enabled or disabled as
required:
99. IRISYS People Counter Setup Software
Then go into the Setup Tool to configure the counting
functionality:
•
•
Setup Tool requires the MS Silverlight add-on
Ensure you have it installed before you get to site!
100. IRISYS People Counter Setup Software
Silverlight will load:
…and it will connect to the counter:
101. IRISYS People Counter Setup Software
Firstly, the “Configuration Wizard” will run through:
•
The configuration Wizard is
run automatically at various
times during the setup process
to ensure the counter is
configured correctly
102. IRISYS People Counter Setup Software
Number of units will be reported:
Click Next
If units have never been configured
before (brand new) they must be
configured with valid IDs:
103. IRISYS People Counter Setup Software
The default Comms ID is 127:
•
•
•
•
Note the message “Find the
device with LEDs flashing”
Confirm that you are setting the
ID for the correct unit
When two or more units are
connected they will not
necessarily be displayed in the
order that they were installed
on the ceiling!
Enter a valid Comms ID of
between 1 and 120
104. IRISYS People Counter Setup Software
For simplicity, it is recommended that you always enter an
ID of 1 for a master unit and for node units use 2, 3, 4, etc.
•
•
Once you’ve entered a valid
Comms ID, click ‘Next’
As long as the IDs are all
unique the Changes will be
verified successfully:
105. IRISYS People Counter Setup Software
Number of units will be reported again:
Click ‘Next’
Then the new settings will be saved.
Again, click ‘Next’:
106. IRISYS People Counter Setup Software
Next you must specify the correct X and Y coordinates:
•
For a single unit 0,0 is valid
107. IRISYS People Counter Setup Software
Next you must specify the correct X and Y coordinates:
•
•
•
The default positions will be
identical for multiple brand new
units
The Wizard will therefore report
a problem
“Unit overlap may be excessive”
108. IRISYS People Counter Setup Software
Think of the units as being positioned on a grid:

116. Disjointed Wide Opening Networks
When setting the X and Y values of units which have been
installed without an overlap, the values do not really
matter.
10m (33ft)
•
For ease of viewing on the
ground plane, X and Y
values can be set closer
than actual, if required:
5m (16ft)
117. Disjointed Wide Opening Networks
But do not set the X and Y values of units too close, as
there could potentially be some, false tracking of targets
between views:
10m (33ft)
118. IRISYS People Counter Setup Software
The higher the counter is mounted, the bigger field of view
will be provided (enter the height as accurately as
possible):
Size of
Field of
view at
2.5m
Size of
Field of
view at
4.5m
119. IRISYS People Counter Setup Software
You can change the mounting height and X, Y coordinates
at any time by clicking the ‘cog’ symbol:
For a single unit, the X and Y coordinates can be left as 0,0.
120. IRISYS People Counter Setup Software
People are counted when they are seen to cross the count
line.
The count lines should therefore be positioned for best
accuracy.
121. IRISYS People Counter Setup Software
With wide opening networks, a target should be tracked
correctly between counter field of views:
If a target is not tracked smoothly, between views, check
your height, X, and Y settings and measurements!
122. IRISYS People Counter Setup Software
Counters installed at different heights, will have different
sized field of views:
The counter at (0,0) is installed 3m high.
The counter at (300,0) is installed 4m high.
123. IRISYS People Counter Setup Software
Any units offset from each
other, will be positioned and
displayed offset on the
ground plane view:
(You will still
need to adjust
the count
lines)
124. Wide Opening Networks
Units that are not installed in a simple straight line must
have appropriate X and Y values configured in order to
reflect their true position:
125. Wide Opening Networks
The direction that the units are pointing on the ceiling
must be considered when configured X and Y coordinates
correctly:
=
126. Wide Opening Networks
In these types of examples, all units must point in the
same direction:
=
127. Wide Opening Networks
In these types of examples, all units must point in the

129. Count Line Configuration
Correct placement of the count lines is the key to
accurate counting
•
•
It is the installers responsibility to position the count
lines correctly for the installed location
Extensive walk testing is advised!
Things to remember:
•
•
•
People must cross the count line in the correct direction
to register a valid count.
People do not have to cross both lines in order to
generate a count increment – both lines work
independently.
Four selectable count modes are available in order to
change the way the count increments are given.
130. Initialisation Requirements
•
•
Count lines must be positioned to allow a certain amount
of target ‘initialisation’.
At the point a target appears it is said to be initialised.
132. Initialisation Requirements
Here the ‘IN’
count line is too
close to the edge
of the field of view
This person was not
counted because he
was ‘initialised’ after
the count line
With the count lines
positioned further into
the field of view
people will be
initialised before
crossing the ‘IN’ line
133. Initialisation Requirements
Arranging the count lines in an arc around a door, is a
common configuration.
•
It allows sufficient
initialisation.
•
And, people who enter
and turn immediately
left or right will not be
missed.
134. Count Line Configuration - Examples
With security barriers at the entrance, count lines
should be positioned between them:
Overhead View
Side View
135. Count Line Configuration - Examples
If initialisation is tight; lines should be angled between
the ends of the security barriers:

136. Count Line Configuration - Examples
If doors can swing into the field of view, lines must be
positioned in an arc around them:
Overhead View
Side View
137. Count Line Configuration - Examples

139. Count Line Configuration - Examples
If doors are automatic sliding type, ensure doors cannot
cross the ends of the lines as they slide open and closed:

140. Count Line Configuration - Examples
For units positioned closer to the lease line (under
cover shopping mall stores) position the lines along the
lease line, ensuring enough initialisation:
Overhead View
Side View
141. Count Line Configuration - Examples
With a shop in a mall entrance, the count lines can be
positioned along the lease line if required.
Remember that passing
traffic will not be
counted even if seen by
the counter.
Only people who cross
the count line will be
counted.
Overhead View
142. Count Line Configuration - Examples
Always position the count lines around the swing of the
door:
Overhead View
Side View
143. Count Line Configuration - Examples
Watch for the possibility of cross traffic. In this case this
person could generate an extra counts:
•
Position the count lines as
close to the door as possible
in order to reduce this
problem (but not at the
expense of initialisation)
•
You can also change the
count mode
Overhead View
144. Count Line Configuration - Examples
Count lines should be positioned from ‘wall to wall’ in a
corner installation:
Overhead View
Side View
145. Count Line Configuration - Examples
Count lines on a wide opening should be configured in a
similar to single units, but across all counter field of
views to encircle the door(s):
Overhead View
146. Count Line Configuration - Examples
Most Corridor-like installations can be configured with
simple straight lines through the centre of the field of
view:
•
•
This usually ensures that there is enough space for
initialisation in both directions
Also, anyone dithering on the count lines should not
generate more counts in one direction than the other
Overhead View
147. Count Line Configuration - Examples
Wide Opening Network installations are installed similar
to single units in corridors with lines through the centre
of the field of views:
Overhead View
148. Count Line Configuration - Examples
In ‘busy’ corridors where office furniture and other
objects can be interacted with, people may not walk
straight through the field of view without stopping.
•
In these cases careful line placement may be required
to avoid counting people who stop in the field of view
Overhead View
149. Count Line Configuration - Examples
In narrow corridors beware of thermal reflections from
the walls. These can generate extra counts if the count
lines are not positioned correctly:
•
Lines should be positioned across the floor only
•
Always bring the lines in from the edges
Front View
Overhead View
150. Count Line Configuration - Examples
For optimum counting through corridors, count lines
should be configured through the middle of the field of
views wherever possible:
Overhead View
151. Count Line Configuration - Examples
Always bring the lines in from the edges:
Overhead View
Side View
152. Count Line Configuration - Elevators
At Elevators, do not stretch count lines across multiple
views in order to count two or more elevators:
Overhead View
153. Count Line Configuration - Elevators
Configure separate IN and OUT lines for each Elevator.
Keep them as close to the door as possible in order to
avoid counting people walking past or waiting nearby:
Move count
lines further
out from the
door if people
exiting the
elevator are
not being
picked up in
time
Overhead View
154. Count Line Configuration - Escalators
Stay clear of the ‘landing zone’ at the top and bottom of
escalators:
•
Position count lines
around the landing zone
•
Always configure ‘UP’ &
‘DOWN’ lines in case
escalator direction is
reversed in future
156. Multiple Count Lines
Additional count lines can be added or count lines removed
at any time:
•
Just click the ‘Add Line’ button to add a line:
•
Click the red ‘X’ to remove a line:
157. Multiple Count Lines
New count lines added will be placed in the same place on
the ground plane view:
159. Multiple Count Lines
There can be between 1 and 8 count lines enabled at once:
•
•
Any count line which is enabled will be logged in flash
Because the amount of flash is finite, only enable the
required number of lines and remove those not in use
160. Flash Memory - Count Log Capacity
The length of time that the flash lasts before older entries
are overwritten depends on the number of lines enabled
and the logging interval:
•
•
Any count line which is enabled will be logged in flash
Only enable the required number of lines and remove
those not in use!
162. Other Settings
Clicking on the Menu/Irisys symbol button will bring up
further options:
Click on ‘Global’ settings.
163. Global Settings
Enter the relevant site details:
Ensure the Date/Time is Set to current date and time.
Click ‘Program’, then ‘Permanent’, before closing.
167. Discrimination Sensitivity
The Discrimination Sensitivity slider affects how
the counter interprets the thermal signature:
•
•
•
•
•
•
A single person is shown as a yellow target
A ‘couple’ is shown as a blue target
If single people are being seen as couples
(blue targets) lower the sensitivity slightly
If couples are being seen as single people
(yellow targets) raise the sensitivity slightly
At very low heights you may need to
lower the sensitivity to avoid over
counting
At very high heights you may need to
raise the sensitivity to avoid under
counting
169. Large Target Couple Counting
This option enables the blue targets. With
disabled, all targets will be yellow and counted
as one only.
•
•
•
•
Normally this option should be left enabled to
allow for the possibility of people walking very
close to each other and getting the correct
count of two
Use the Discrimination Sensitivity slider to
adjust this behaviour
If over counting is proving to be an issue
this option can be disabled
Disable if supermarket shopping carts are
being counted, for example
171. Extended Grouping Mode
This option is provided to give more control of the
internal grouping of targets seen by the counter.
•
•
•
•
•
•
Normally this option should be left disabled
Enabling this option will mean that more targets will
be joined together and counted as one
Even targets very far apart will be joined together and
counted as one
Re-adjust the Discrimination Sensitivity slider to affect
this behaviour
Enable if supermarket shopping carts are
being still being counted, for example
Enable to provide a basic ‘shopping unit’
count – all people entering together will
be counted as one only
173. Count Mode Setting
Set the correct count mode.
It is the installer’s responsibility to
select the appropriate counting mode
based on:
•
•
•
•
The Count Line configuration
The behaviour of people
What you want to count
What you don’t want to count
(In most cases the default ‘Deferred’ count mode will be
the recommended count mode)
174. Count Modes - Immediate

178. Deferred Initialisation
Deferred Initialisation should be left disabled in most
cases:
•
•
•
When enabled it adds more checks
to a thermal signal before it is
initialised as a valid target
This means initialisation takes
much longer
This is to help prevent ‘Ghost
targets’
179. Deferred Initialisation
Ghost targets are targets seen on the ground plane
when no actual person is walking underneath a counter
They are caused by rapid temperature change
of the floor immediately below a counter
An example situation where ghost targets may
be seen is here:
•
•
The sun shines through
a glass entrance and
makes the floor very hot
...
Side View
180. Deferred Initialisation
•
•
•
When the doors open, wind blows in through the
opening and rapidly cools down the floor
This cooling action moves through the field of
view which the counter will detect as a person
Ghost targets move in a random meandering
pattern
Overhead View
Side View
181. Deferred Initialisation
Because Ghost targets move differently to targets from
genuine people they can be recognized by the counter.
This is done with extra target checks before initialising.
Because of initialisation takes longer with deferred
initialisation, it should not be enabled by default.
•
•
Deferred initialisation should only
be enabled when genuine ghost
targets have been confirmed or
strongly suspected
Count lines will also need to be
modified to accommodate longer
initialisation requirements on
genuine targets

If working underneath the counter,
path maps will be mixed up (below
right), so select ‘Reset Path
Mapping’
184. Path Map Data
The path map function allows line placements to be
verified:
•
•
Lines should not be positioned in ‘initialisation areas’
(light blue areas)
Lines should stretch across ‘well trodden paths’
(darkest blue) to ensure people aren’t being missed

188. Counter Configuration
Alternate method of connection is via serial lead
• USB adapter is also provided with serial cable
• Installer must run executable version of setup tool
• Executable version will also connect via IP if required
• If you do not know the IP address of the counter, or the
password, you must configure via serial
189. IRISYS People Counter Setup Software
Connection to the counter can be via Serial or IP:
•
Connect the serial lead to the counter and choose the
correct COM port
190. IRISYS People Counter Setup Software
Serial version of the setup tool is identical to the setup tool
via IP
•
Only difference is additional ‘IP config’ option on main
menu
191. IRISYS People Counter Setup Software
This is the only way to recover from a forgotten IP address
or forgotten (changed) password:

Note: you cannot configure DNS settings via serial
With a covered mall shop entrance there will be no reflected temperatures from the sky and you can afford to mount the counter closer. This can make it easier to configure the count lines later (see later slides). In these environments it may be that the ideal mounting position is directly above the lease line (assuming that the height is ok).
For a door situated against a wall in this way, the counter should be positioned away from the wall. This then maximises the amount of field of view available, thereby giving better initialisation and more options for placing the count lines.
If you exceed the maximum mounting height, severe under counting could result.
If you exceed the maximum mounting height, severe under counting could result.
If you drop below the minimum mounting height, severe over counting could result.
Always try to get close to the optimum height if you can. Even raising the counter by as little as 10cm will help a lot.
If people stop in the field of view the counter will lose them after a period of time (5-10 seconds). When they move again they will be picked up as a new target. This can cause count inaccuracies, if people are not initialised again in time after a stopping moment. Or people can be counted again and again if continually stopping and then moving over the count line(s).

Always configure the correct X and Y positions so that tracking will function correctly between units.
This is why the height setting must be entered accurately. The counter needs to know how high it is installed so that it knows how big the field of view will be and therefore how big targets will be. It can then correctly identify couples and singles, etc.
Note setting this value higher does not increase the size of the field of view. This is fixed based on the actual height – why the counter needs to know.
For a single unit the X and Y coordinates don’t make much of a difference as they are really required when configuring two or more units on a wide opening network. See later slides.
The Height setting must ALWAYS be entered, and accurately.
For this functionality to work correctly you must accurately enter the height and X,Y values. If any values are incorrect then the tracking between units won’t work correctly and individual people could be counted more than once (depending on their walking patterns).
The four count modes are explained later on in the presentation.
The three examples show different initialisation times. The longest time is shown on the right - this is a particularly bad example of initialisation time, shown for demonstration purposes, and you would typically expect targets to be initialised sooner than this.
Positioning the count lines too close to the edge of the field of view will invariably lead to under counting due to targets being initialised after the count line. In practise this may well manifest itself with OUT counts being a lot more than IN counts, for example.
This is a recognized count line configuration which works accurately in the majority cases. It allows for initialisation before reaching the line and also makes sure people have to cross the count line – they cannot miss the count line at all.
This provides enough initialisation on the way in, and more than enough on the way out.
This provides enough initialisation on the way in, and more than enough on the way out.

This can make it easier to configure the count lines later (see later slides). In these environments it may be that the ideal mounting position is directly above the lease line (assuming that the height is ok).
This is very important which some people do not realise is the case. Anyone can walk through the field of view, but only those people who cross the count line(s) will be actually be counted.
This walking behaviour can be disregarded by selecting the right count mode, see later slides.
