Webcam Watcher's Motion Detection feature can compare pictures to see if there is any motion or change, and can be set up to only save pictures if there is motion or other change between frames.

Motion Detection Settings

Motion Detection settings dialog

Webcam Watcher's motion detection can be tuned for specific purposes for each webcam if required.

You can open the Motion Detection Settings dialog by clicking the Motion Detection LED at the bottom of the screen (or choosing Tools > Motion Detection Settings from the menu)

There are three sliders that let you control three parameters:

Note The Motion Detection Settings can be changed for each webcam, by selecting the Current Webcam button, or you can change the global settings by clicking the Default Settings button

Motion Detection Bargraph

The right-most object on the bottom toolbar is the Motion Detection Bargraph.

Location of the Motion Detection LED

This shows you how much motion is currently occurring. Note that the graph is divided into a red and green section.

When the graph gets the the green area, motion is detected. You can adjust the position of the red/green boundary using the Percentage of cells changed slider (right click on the bargraph).

The bargraph changes when new pictures arrive (and motion detection is enabled), but also when you scroll back through saved pictures.

This lets you see how the current motion detection settings behave on saved pictures, allowing you to fine tune the settings.

Clicking the Bargraph opens the Motion Detection Settings dialog.

Enabling Motion Detection

To enable motion detection you can either:

Global Save Settings

Global Save Settings dialog

You can override a webcam’s normal Saving Frames setting using Global Save Settings.

For example, you can force all webcams to save only when motion is detected, or to turn off saving entirely.

You can see the current Global Save setting on the to toolbar. Click the down arrow to change.

This lets you turn on motion detection for all of your current webcams without editing them.
