Cortex™ - Rules ManagerVMD (Video Motion Detection)The VMD Alarm activates an alarm whenever any change is detected within the ROI
Use cases• Perimeter surveillance –
Monitorthe area between two physical or virtual fences for detection of object motion in said area that constitutes a perimeter breach.
4
Cortex™ - Rules ManagerStatic Object AlarmThe Static Object Alarm activates an alarm upon detection of a subject that remains static for more than a pre-defined number of seconds.
Use cases• Abandoned object – Detect
packages / objects left by moving pedestrians in a public venue.
5
Cortex™ - Rules Manager•Presence Alarm
• The Presence Alarm activates an alarm instantly once a subject is present in the specified ROI, regardless of motion or direction.
Use cases• Intrusion into restricted
areas – Viewing a relatively small area where persons are prohibited. alerts on the appearance of a person in a window or a doorway.
6
Cortex™ - Rules Manager•Path Detection Alarm
• The Path Detection alarms are used to detect whenever a subject crosses from one area to another in one direction or both directions.
Use cases• Motion pattern – In this use
case the source zone may be placed in any image location relative to the detection zone provided that the object is tracked between the two zones.
7
Cortex™ - Rules ManagerObject removal AlarmThe Object Removal Alarm activates an alarm whenever an object is fully removed from the specified ROI
Use cases• Object displaced – Detect
displacement of object from its defined location as defined by the detection zone.
8
Cortex™ - Rules ManagerObject removal AlarmThe Object Removal Alarm activates an alarm whenever an object is fully removed from the specified ROI
Use cases• Object occluded – Detect the
partial / complete occlusion of the object for more than a user-defined time limit.
9
Cortex™ - Rules Manager•Object started Alarm
• The Object Started alarm activates whenever a static object starts to move inside the ROI.
Use case• Guarding on existing items
– Detect static object starting to move such as a car exit from its parking.
10
Cortex™ - Rules Manager•Directional motion Alarm
• The Directional Motion alarm activates whenever an subject deviates from its direction in a pre defined angle.
Use case• Directional motion
detection – Similar to motion detection with a direction criterion imposed, in order to assign special meaning / priority to an intrusion tactics in certain directions.
11
Cortex™ - Rules Manager•Directional motion Alarm
• The Directional Motion alarm activates whenever an subject deviates from its direction in a pre defined angle.
Use case• People moving in wrong
direction – Detect people traveling the wrong way in busy environments, such as airport security exits.
12
Cortex™ - Rules Manager•Speed Alarm
• The Speed alarm measures speed and activates an alarm whenever a subject exceeds the designated speed bounds
Use case• Fast speed vehicles – Detect
vehicles driving faster than the maximum allowed speed.
• Low speed vehicles – Detect vehicles driving slower than the minimum required speed
