when the VMD is triggered and is best

used under controlled lighting, i.e.

so there are no false triggers due to

ambient light changes.

Static - The reference image is collected on

startup and is never updated. This

would be used in ‘sterile’ areas where

there are no changes expected.

Zone disabled - This will disable the zone mode.

the camera channel being congured. There are ve settings to

choose from: Indoor High, Indoor Low, Outdoor High, Outdoor

of pixels in the selected zone that must change for the VMD event
