Honeywell K14392V1 To Mask Part of a Video Feed from Motion Detection, False Positives, Solutions

Enhancing Video for Security

To Mask Part of a Video Feed from Motion Detection

1.Check that Record/Motion/Image is selected, as in figure 7–11.

2.Click , the Edit motion mask command; see figure 7–11.

3.You have the option of clicking to Show gridlines. The video image on the Video tab is overlaid with a grid.

4.Click on areas of the video feed that you need to mask. To mask more than one cell with

one click, press and hold the Ctrl key on the PC’s keyboard while you click. This option masks 3×3 cells at once.

False Positives

A false positive (also known as a false alarm) is a common situation that triggers motion detection without posing a security risk. Sources of false positives can include: the sun’s glare reflected on windows and cars, shadows, turning vehicle lights or building lights on and off, direct sunlight as the day progresses.

Solutions

More than one technique can be used to reduce false-positives:

•Masking. You can mask areas of a feed where movement is of no concern.

•Scheduling. Alarms can be scheduled not to “ring” only at certain times. See Alarms and Scheduling, on p. 109.

•Camera placement. Software settings and scheduling can compensate for many camera problems but not for all; for example: direct sunlight may require moving a camera or shielding it from sunlight.

•Camera position. A camera in a building is an effective way to use motion detection, since lighting can often be controlled. However, a window or vista, which shows a roadway or pedestrians, can trigger motion detection.

•Motion search. There are cases when performing a timely search for motion is more effective than constantly testing for motion. See Motion Search on p. 120.

Video settings and motion detection

When an alarm based on motion detection is enabled, changing picture settings (brightness and so on) can trigger that alarm. You can limit the triggering of alarms by using the Delay slider in the motion detection controls. See Cameras, on p. 65 and Events Defined, p. 187.

Customizing Detection: Scheduling

Scheduling alarms. Motion is detected at all times. There may be times when movement may not be of any interest, such as during business hours. These times can be scheduled to not trigger alarms. See Alarms and Scheduling, on p. 109.

PTZ cameras. On a PTZ camera, motion panning, tilting or zooming triggers motion events. You have the option of scheduling alarms for times when a PTZ camera is not moving.
