Auto Height
The Time of Flight data that all Vector variants use for tracking people through their field of view is also used so that they can measure their own installation height as part of the installation process.
A new device with no height information stored will prompt the installer to configure the height as one of the first steps but the height measurement process can be prompted at any point if required.
Also as part of the height measurement process the Vectors internal accelerometer is accessed and the current values stored as part of the configuration. The height and accelerometer details are then used to correctly display the field of view on the main Counting setup tab so that it reflects exactly what the device can actually see.
Periodically the height and accelerometer values are re-checked and if the current values are significantly different to the stored values, a warning status flag will be set. Changes in height and/or tilt values would indicate a change to the installation which should be checked, for example a tilt change of a device installed on a ceiling tile may indicate that the tile was moved to access the ceiling void and may not have been put back in the right orientation, or a large tilt change would indicate that a device has possibly been hit by something and is now looking at a slightly different area. Units that are tilted a different way will need their lines/zone configurations checking and moving to the new view, with a possible trip to site to correct the tilt angle if required.
Automatic Prompt
The automatic prompt looks like this and will be shown when accessing the Counting tab for the first time:
Until the device knows its own installation height it will not be able to count or track anyone so it is strongly recommended that this step is performed to ensure that the device can be operational and at the very least start building up some path map data, which can be used later for assisting with counting setup and line/zone positions.
Although all Vector can measure their own installation height, they have to be instructed to take a measurement which is then stored internally, This automatic prompt helps ensure that an initial height measurement is taken.
In 99.9% of all cases you should simply tick the 'Auto Height' check box and then click the 'Auto Detect' button:
After a few seconds the measured height will be displayed. Click the 'Save' button to finish and go into the Counting setup.
Triggering a Height Measurement
Whenever the physical installation is adjusted or changed in anyway, the Vectors height measurement routine should be triggered to ensure it has the correct details.
To trigger a height measurement, firstly click the 'Devices' button to show the Devices window if its not already open:
On the Devices window, click the yellow Edit button:
The current height, as well as the installation tilt angles will be show:
You can now click the Auto Detect button to both measure the mounting height and update the installation tilt angles.
Manually Setting a Height
You can manually configure a height if required, but in all cases this should be considered a backup option to the Auto Height function, which is only to be used when the Auto Height function fails for some reason.
To set a height manually, simply type in the height and click the 'Save Device' button:
