What is “threshold”?
The threshold is the minimum value for the camera to detect motions on the
image during the motion detection buffering. Setting the threshold lower allows
subtler changes to be detected. Setting the threshold higher allows only bigger
changes that might occupy half the image to be detected.
What is “sensitivity”?
The sensitivity is the level of brightness detected as motion by the camera. A
high sensitivity setting enables t he camera to detect slight brightne ss changes.
Lower the sensitivity to make the camera detect only big brightness changes.
Note
• Lowering the threshold and increasing sensitivity enables the camera to
detect slight movements easily.
Note
• Motion Detection is activated by changes in the outline of objects and
brightness changes. This feature is designed to decrease false detections
due to overall brightness changes caused by sunlight. But in some cases,
the camera may falsely detect rapid brightness changes by artificial light
such as fluorescent light. In other cases, the motion detection function on
the Network Camera Recorder may detect objects and brightness
changes. The way to detect motion differs between the camera and the
Network Camera Recorder (customer-provided).
The Threshold is displayed. Only motion above the Threshold is detected.
