Introduction

The Vector Time of Flight devices have a field of view in which they can detect and track people as they walk underneath. This is different to a 'curtain' type sensor, and a field of view provides options for both counting across a virtual count line (IN and OUT counting) and monitoring the number of people in an area (zone based counting).


Mounting Height Range 

Vectors should be installed within their mounting height range. Devices installed outside of the allowed mounting height range will not operate correctly and will go into a error state.

The Vector 4D mounting height range is between 2.0m and 4.5m.
Note that the field of view of a Vector is not square, and the width is longer than the length.

The size of the field of view rectangle is shown below:

Vectors should always be installed within their operating height range, as above. If a Vector is installed too high or too low, then it will not operate and will go into error.

Where a ceiling is too low, other mounting locations should be sought.
Where a ceiling is too high, Vectors can be dropped by a pole so that they are within their operating height range, or can be installed on a bracket from the wall. Note the preferred distance from the wall - and hence length of bracket required - below.
Vector base plates have many useable mounting holes for connecting to a 'back box', or directly onto a pole or bracket. Installation of Vectors and hence sourcing of appropriate brackets is the installers responsibility.
