Introduction

Detection Areas are where you want the radars to look for targets. You can define one or more areas and apply tracking parameters to optimise the detection of people or objects within those areas. You can also over-lay one or more areas to create exclusion and partial tracking areas. You can add as many detection areas as you need, they do not need to be adjacent and using multiple areas provides the benefit of using custom detection settings in each area. This can help when fine tuning the system to get the optimal detection performance with minimal false alarms.

The creation of new Detection Areas is generally achieved in two stages:

  1. Create rough initial outlines for the Detection Area(s).

  2. Use live radar data to fine tune the area outline according to how the radar sees the surrounding environment. For example the radar can see trees, hedges and buildings. So you can use this information to ensure your detection area is optimal for your site.

Remember that the HDR radar offers centimetre accuracy so you can refine the placement of your detection areas to the same accuracy.

Creating a Detection Area

  1. Enable the Configuration Function, then select Areas in the Configuration Tree.

  2. In the Configuration Panel, select New, then select Area to activate the Create New Area Wizard.

  3. In the Create New Area Wizard, select 'Detection' from the Type drop-down list. Configure the rest of the options, and select Finish.

  4. Use Standard Creating and Editing to edit the shape and orientation of the Detection Area and position the label.

  5. Edit any other details through the area configuration form as required.

  6. Select Save.

Radar Detection Area Setup

  1. Next, select the site in the Configuration Tree, then select Radar Detection Area Setup in the Configuration Panel.

  2. The Radar Detection Area Setup window will open. Choose a Tracking Parameter to apply to your Detection Area from the drop down list, then select Finish.

  3. Your Detection Area has now been assigned the selected Tracking Parameters. Tracking Parameters determine how and what the tracker detects and tracks. Learn more about Tracking Parameters here.

Learn how to manually assign Tracking Parameters on the Detection Areas page.

Fine Tuning Detection Areas

Once each radar sensor has been aligned and valid data is being received, it should then be possible to see the objects such as fences, hedges, trees, buildings, road boundaries and the surroundings. You can now use these images to ensure that the rough outer areas created earlier are shaped as tightly as possible around the area(s) that they need to monitor.

If your radar are not aligned, you will need to align the radar data to your Background Image before you start the fine tuning process.

To fine tune an area:

  1. Within the map or in the radar group select the relevant Radar.

  2. Within the Selected Entity Info Panel, select Radar Data, to overlay the live radar signal within the site map. It is possible to simultaneously overlay the output from two or more radar sensors. However, this uses a sizeable amount of processing power so it is advisable to show no more than two or three sensor overlays at a time.

  3. Select the source Raw.

  4. Ensure you can see the raw data where you want to apply the detection on the map.

  5. Click on the Detection Area to select it, then configure it using the Creating and Editing. Use the Raw Data to shape the Detection Area around visible objects and boundaries. In this example the detection areas is being redrawn around the tree line to ensure we achieve maximum detection but without extending the area into the trees where the radar cannot see.

  6. When the area has been fine tuned, select Save to store the new area shape.

For parts of the area that are further from the radar sensor, any given object will produce a wider trace due to the beamwidth of the sensor. Therefore, it may be necessary to widen the area as it stretches away further from the sensor.
