AXIS Q7411 Video Encoder AXIS Video Motion Detection AXIS Video Motion Detection AXIS Video Motion Detection is an application that detects moving objects in the camera’s field of view. When a moving object is detected, AXIS Video Motion Detection sends an alarm that can be used by the Axis product or by third-party software, to, for example, record video or send a notification. AXIS Video Motion Detection 3 is included with the Axis product and is available under Setup > Applications.
AXIS Q7411 Video Encoder AXIS Video Motion Detection It is recommended to only enable visual confirmation for one channel at a time. Make sure to disable visual confirmation before starting configuring another channel. Clicking Save will save changes on all channels. Include Area The include area is the area in which moving objects will be detected. Objects moving outside the include area will be ignored. The object will be detected also if only a part of the object is inside the include area.
AXIS Q7411 Video Encoder AXIS Video Motion Detection Note To use visual confirmation, Internet Explorer and AXIS Media Control (AMC) must be used. When visual confirmation is enabled, all moving objects found by the application will be encircled and followed by polygons. A red polygon indicates that the object is found and is detected as a moving object. A green polygon indicates that the object is found but is ignored because it is not in the include area or because of one of the ignore filters.
