Motion Detection
Motion detection enables you to define a region of interest in the camera’s field of view which can be
used to trigger an Event Action. Multiple areas of interest can be selected in the field of view but only
one Event Action may be triggered.
Motion Detection Best Practices
To ensure you get the highest quality results when using Motion Detection on the camera it is
recommended that you adhere to the following:
• An object exhibiting motion needs to be at least 8x8 pixels in size to be detected.
• The color of the object (in gray scale) should be approximately 10-15% different than the
background.
• Exclude the Time Stamp region from motion detection, because the time stamp changes
constantly and could register as motion.
• Try not to point cameras into sunlight, because high brightness prevents detection of
movement of bright objects such as a person with a white shirt.
• Avoid areas with persistent motion, such as trees, blinking lights, or spinning signs, by
using an appropriate region of interest.
