3.5. Motion
Display live motion capture preview
If enabled, the "Snapshot & Motion" window will be available to preview the current frame captured by the motion detector, and (if enabled below) motion areas will be highlighted in red.

Only display preview images when motion is detected
If enabled, the "Snapshot & Motion" window will only be updated when motion is detected. If disabled, the "Snapshot & Motion" window will be updated every time the motion detector samples a frame from your camera (usually once every half-second or so).

Highlight detected motion in red
If enabled, the motion detector will automatically highlight areas of motion with a translucent red grid. This may assist in determining exactly where VideoMonitor is detecting motion on the camera.

Motion capture sensitivity
Controls the sensitivity of VideoMonitor's motion sensor. Increased sensitivity may result in better detection of motion, but it may also result in more frequent "false positives" (eg: where changes in lighting, or static/"snow" in the camera cause the motion detector to incorrectly detect motion).

Decreasing the sensitivity will reduce false positives, but may cause VideoMonitor to "miss" some motion, especially if the an object moves slowly across the field of view.

Motion capture threshold
Controls how much movement is required before the motion sensor is triggered. If the video from your camera appears "snowy" or has some static, you may need to increase the threshold to make VideoMonitor ignore the snow.

If you find that slow-moving objects are not detected accurately enough, you may need to increase this setting.

Motion capture frequency
Motion capture is achieved by periodically grabbing a snapshot from the camera, and comparing it with the previous snapshot to see what (if anything) has changed. If the snapshots are significantly different (eg: if someone has walked into the camera's field of view), the motion sensor will be triggered.

This setting controls how often these "motion capture" frames or snapshots are taken and compared. Increasing the frequency may increase the motion detector's accuracy, but will significantly increase the amount of processing power required by the motion detector.

Decreasing the frequency will reduce the processing power required by the motion detector, but may cause the sensor to be less accurate.

Detected motion: Save snapshot
If enabled, the motion detector will automatically save a snapshot when motion is detected.

Detected motion: Play a sound
If enabled, the motion detector will automatically play the selected sound (wave file) when motion is detected.

Detected motion: Run a program
If enabled, the motion detector will automatically run the specified program when motion is detected.

Wait at least ... before re-triggering on motion
A single event (eg: someone walking past the camera slowly) may trip the motion sensor repeatedly or continuously over a short period of time (eg: until the person steps out of the camera's field of view).

If you are using the motion detector to trigger an event(eg: play a sound, save a snapshot, run a program, or send an instant message), you probably don't want these events to trigger more than once for a single motion event.

This feature is used to set a "cooldown period" after the initial event is triggered; during this period, no additional events will be triggered, even if motion is still detected during the period.
