VCA Filters - Speed Filter
Speed Filter
The speed filter provides a way to check if the speed of an object which has triggered an input is moving within the range of speeds defined by a lower and upper boundary.
The channel must be Calibrated in order for the speed filter to be available.
Commonly this rule is combined with a presence rule, an example rule graph is provided to illustrate this below.
The following image illustrates how such a rule combination triggers on the car moving at 52 km/h but the person moving at 12 km/h falls outside the configured range (25-100 km/h) and thus does not trigger the rule.
Property | Description | Default Value |
|---|---|---|
Name | A user-specified name for this rule | "Speed #" |
Can Trigger Actions | Specifies whether events generated by this rule trigger actions | Active |
Input | The input rule | None |
Min Speed | The minimum speed (km/h) an object must be going to trigger the rule | 0 |
Max Speed | The maximum speed (km/h) an object can be going to trigger the rule | 0 |
Typical Logical Rule Combination
The below example logical rule checks if an object triggering the presence rule attached to zone Centre, is also travelling between 25 and 100 km/h as specified by the speed rule Speed Filter 25-100 km/h.
Only the Speed Filter is set to Can Trigger Actions, meaning only this component of the logical rule will be available as a source for actions. Additionally, any activity generated by the speed filter will have the event type Presence
