Introduction

The Area Speed Limit rule combines an area check with a property check. This checks each target to see if it is travelling above a speed whilst also being in the specified area. In this example, if both conditions are met, an alarm is raised and a camera is tasked to follow the target.

Area Speed Limit Rule with Break Count

The area speed limit with a break count is the same rule architecture as above but this configuration uses a break allowance on the area check. This means the track has to be in the area for number of sightings before the rule is broken. In this example the track has to be in the area for at least two sightings before the rule can be broken. An additional break allowance can be added to the property check if required. In this situation both break counts would apply, but independently.
