Calibration

Setting Description

Type

Select the type of calibration. Manual allows you to set the camera position. Automatic allows the video analytic to set the camera position and field of view. Uncalibrated runs the video analytic without camera position and field of view information.

Zoom In

Click to make the calibration diagram larger.

Zoom Out

Click to make the calibration smaller.

Field of view (degrees)

Define the horizontal field of view (in degrees) for the camera.

Pan (degrees)

Define the rotation around the vertical axis of the camera in relation to the scene.

Twist (degrees)

Define the rotation around the horizontal axis of the camera in relation to the scene.

Height (meters)

Define the vertical distance from the camera to the ground.

Distance (meters)

Define the horizontal distance from the camera to the center of the scene.

Sensitivity

Setting Description

Maximum Hidden Seconds

Set how many seconds an object can remain hidden before the video analytic stops tracking the object. If, after this time elapses, the video analytic detects the object again, the video analytic treats the object as a new object (i.e., the video analytic gives the object a new ID).

Minimum Confidence

Set how confident the video analytic must be in object detection to classify the object.

Minimum Tracking Threshold

Set how confident the video analytic must be in object detection to track the object.
