To configure create the Multiple Objects objects detector, do the following:
- Create the required
detection tool - detector and specify its parameters (see
Creating detection tools- Configuring detectors and their sub-detectors).
- Below the created
detection tool- detector,
click - click Create… → Multiple
Objects- objects.
By default, the detection tool detector is enabled and triggers set to generate events when the number of objects in the detection area exceeds the value specified in the detection tool detector settings.
If necessary, you can change the detection tool detector parameters. The list of parameters is given in the table:
| Parameter | Value | Description |

detection tool | detector is enabled by default. To disable the |
detection tool the value Objects detection tool | detector name or leave the default name |

| Basic settings |
| Maximum object height | 100 | Specify the maximum object height as a percentage of the frame size for the |
detection tool to triggerdetector to generate an event. The value must be in the range [0.05, 100] |
.| Note |
|---|
| The values of the maximum object height must be equal in the settings of |
|
the Object Tracker and Multiple Objectsthe Object tracker and Multiple objects. |
|
| Maximum object speed | 500 | Specify the maximum object speed per second for the |
detection tool to triggerdetector to generate an event. The value must be in the range [0, 500] |
.In - In Axxon One, speed is a conditional value that is calculated using values of different dimensions. The speed calculation algorithm takes into account both the frame width and its height.
- For a visual understanding of the speed values, we recommend specifying the speed when searching the archive (see Configuring minimum and maximum object speed).
