Introduction

This quick guide discusses the Counting functionality available on the Irisys Vector devices and how to configure it. A full understanding of the below settings is essential in order to achieve the high accuracy that the Vector 4D devices are capable of.

To be able to access these settings, you must first make a setup connection to the Vector unit; see separate guide: Irisys Vector 4D - Making a Setup Connection.

 

Instructions

The majority of count data is acquired via virtual line crossing detection. A brand new Vector will come with two count lines enabled, and will require very little configuration for standard 'IN' and 'OUT' counting.

The first thing to note is that all Count lines are directional (as indicated by the line end arrows) and people must cross the line in that direction to yield a count increment.
Line crossing count values are shown next to the corresponding register within the ‘Registers’ dialog window.
Standard IN and OUT Count Lines will usually be positioned in the same location within the field of view. Only in specific circumstances will they be separated. Note that some register types, such as Occupancy, require lines to be in the same place.

Count lines can be moved and shaped within the 'ground plane view'.

Therefore, for the most accurate counting, these count lines must be positioned in a suitable location and arrangement within the active field of view so that anyone that should be counted will cross the corresponding count line.

To move and position lines the setup must be in ‘Line edit mode’:

 

Lines can now be moved by clicking and dragging. By default, lines are straight but additional ‘drag’ points can be created by clicking on the smaller circles in the middle of a straight-line segment. In this way, complex arrangements can be made as required.

It is important that lines are only placed over the floor where people can physically walk. If required, you must move the ends of lines so that no part of a line is mapped up a wall, or anywhere where it is not possible for a person to walk. Additionally, if counting IN/OUT of a door, and the door can be seen opening and closing within the field of view, lines must be positioned across the floor in front of the door, well away from that movement. When a swing door opens toward the Vector, it is normal in these cases, to configure an arc arrangement on the floor just outside the swing of the door.

Always switch between ‘Video View Mode’ and ‘Line Edit Mode’ to ensure that your line positions are suitable, and are only mapped across the floor.
