There are two parameters for setting the motion detection: Sensitivity and Percentage
.
In the
illustration above, frame A and frame B are two sequential images
.
Pixel differences
between the two frames are detected and highlighted in gray (frame C), and will be
compared with the sensitivity setting. Sensitivity is a value that expresses the sensitivity to
moving objects. Higher sensitivity settings are expected to sense a slight movement while
smaller sensitivity settings tend to neglect it. When the sensitivity is set to 70%, the Network
Camera defines the pixels in the purple areas as “alerted pixels” (frame D).
Percentage is a value that expresses the proportion of “alerted pixels” to all pixels in the
motion detection window. In this case, 50% of pixels are identified as “alerted pixels”. When
the percentage is set to 30%, the motions are judged to exceed the defined threshold;
therefore, the motion window will be outlined in red.
For applications that require higher security management, it is suggested to set higher
sensitivity settings and smaller percentage values.
Camera control
This section explains how to control the Network Camera’s Pan/Tilt/Zoom operation by
connecting with a PTZ driver or scanner via RS485 interface.
RS485 Settings
Disable: Select this option to disable this function.
PTZ camera: Select this option to enable PTZ operation.
To utilize this feature, please connect the Network Camera with a PTZ driver or scanner via
RS485 interface first. And then you can configure the PTZ driver and RS485 port settings in
