Introduction

This quick guide discusses the Smart Boundary register type. This register will count people in a more intelligent way than a simple line crossing register. It is a single line register with multiple configurable parameters – staff detection, height measurement, grouping and movement.

The smart boundary register is able to count groups of people as one, based on count line timing and the distance between individuals as they cross the counting line. It is also able to correctly assign count increments when people dither within the field of view, and cross multiple lines repeatedly.

If connected to a Vector via an Estate Manager connection, make sure you select the ‘Live View’ option to make changes

Instructions

To add a Smart Boundary register:   

Click the plus symbol (+) on the Register dialog window,
Then choose the "Smart Boundary" type register and click [Next].
Give the register a meaningful name and click [Next]
Enter values for the seven required sections, see below for more details on each: Minimum Height Maximum Height Entry Timeout Exit Timeout Maximum Group Size Maximum Time Between Targets Maximum Distance Between Targets And the optional section: Staff Detection Click [Next] for the Summary to review Then click [Add Register] to complete the process

Sections: - Minimum Height & Maximum Height Count people in the height range only. - Entry Timeout (seconds): This setting helps deal with U turn events. In order to generate a count increment, a person (or group) must cross the line in its configured direction and stay crossed for at least the Entry Timeout period (from point A to point B). If they turn around and go back across the count line before the Timeout is reached, they will not generate a count increment. - Exit Timeout (seconds): This setting helps deal with cross walking events. In order to prevent unwanted additional counts, caused by people walking through the field of view, a minimum Exit Timeout can be configured. The Exit timeout means that people will only generate a count increment if they stay on the ‘wrong side’ of the line for longer than that setting (from point A to point B).Setting a long enough timeout value will allow any cross traffic within the field of view to be ignored. - Maximum Group Size: This setting determines the maximum number of people crossing the count line, one after the other, that will be counted as part of the original group. For example, if this setting is 4, and 20 people walk in together, they will be split into a minimum of 5 groups (of 4 people). In order to take advantage of the other Smart Boundary settings in order to count everyone on the same basis, set this to 1. - Maximum Time Between Targets (seconds) & Maximum Distance Between Targets: These settings determine the time and distance that a person must be from the last person to cross the count line, for them to be included in the same group (up to the maximum group size). For example, if the time setting was 2 seconds, and the distance setting was 100cm, any person crossing the count line less than 2 seconds after the person in front and no further away than 100cm, would be considered part of the same group and would not generate an additional count increment. But if they were more than 2 seconds behind or more than 100cm away at the point at which they cross the count line, they would be considered a new group and an additional count increment would result. - Staff Detection: ‘Off’ – everyone is counted ‘Exclude staff’ – ignore everyone wearing a lanyard ‘Staff Only’ – only count people wearing a lanyard

Multiple Directions

Remember that a smart boundary register consists of a single directional line and the advanced rules that operate on that line. Therefore, for traditional IN and OUT counting, a pair of smart boundary registers would be required - one for each direction. When using two smart boundary registers in this way, each one should be configured with identical settings, and with the lines positioned in the same place in the field of view - only the direction of each line should differ (indicated by the arrows, shown right).
