Introduction

Closest mode causes all cameras within the group to follow only the objects that are in their immediate vicinity.

The cameras will continuously update to look for closer tracks. 

Below are a series of examples of how cameras assigned to the Closest mode, or in a Closest Group, can monitor Tracks.

Closest Group Settings

Open

Group Type: The type of camera group; in this case Closest camera group.

User ID: A user friendly ID.

Name: The name allocated to the camera group.

Enabled: The option to enable this group, which is selected by default.

Use Priority: This controls which targets are selected to be followed, and by default it is not enabled. However, there are some examples shown here: Closest | Priority.

Target Expiry Time: This specifies how long a target will be kept alive whilst the system waits for an update.

Min Follow Time: The minimum length of time spent following targets before looking for another suitable target to follow.

Max Follow Time: The maximum length of time spent following targets before looking for another suitable target to follow.

Classification: Select what type of targets should be followed. By default this is set to all classification models.

Priority: Select the priority level to restrict all cameras in the Closest Group to only follow targets of the selected priority or higher. Any targets of a lower priority will be ignored. By default this is set to Lowest.

Camera Coast: Select this option if you want the camera to continue to follow in the target’s last known direction when it is no longer being tracked.

Coasts Allowed: How many times the camera should follow a coasted track before giving up.

Minimum Sightings: The minimum number of sightings a target should have before it is followed by a camera.

Default

Single Camera

• The camera views the track in closest proximity to it. 

• As tracks move, the camera will change its view to the new closest track.  

Open

Double Cameras

• The camera views the track in closest proximity to it. 

• As tracks move, the camera will change its view to the new closest track.  

• As each camera is in a separate group, they will both view the track closest to them, even if this is the same track. 

Double Cameras, Single Group

• The camera views the track in closest proximity to it. 

• As tracks move, the camera will change its view to the new closest track.  

• The cameras will both view the track closest to them. However, they are in the same group. Therefore, if both camera's are closest to the same track, one camera will switch to viewing the second closest track.

Multiple Tracks 

• The camera views the track in closest proximity to it. 

• As Tracks move, the camera will change its view to the new closest track.  

• The cameras will both view the track closest to them. However, they are in the same group. Therefore, if both camera's are closest to the same track, one camera will switch to viewing the second closest track.

• The other tracks will not be viewed, unless they move towards the cameras and become the closest track. 

Priority

Priority Multiple Tracks

• The camera views the track in closest proximity to it, in the Priority Detection Area (red).

• When a Detection Area is given Priority, only tracks within the Priority Area will be viewed. 

• As tracks move, the camera will change its view to the new closest track (in the Priority Detection Area).  

• The cameras will both view the track closest to them. However, they are in the same group. Therefore, if both camera's are closest to the same track, one camera will switch to viewing the second closest track.

• The other tracks in Priority will not be viewed, unless they move towards the cameras and become the closest track.
