![]() ![]() However, if there is still motion in the include area after the new configuration is set, and no exclusion filter hinders the alarm to be sent, the event will be set to active directly after new configuration is applied. This will cause ongoing recordings to stop, and for multichannel products all cameras are affected simultaneously. The application is not restarted and any ongoing events will be set as inactive when the new configuration is applied. Set the configuration of the application. It will eventually also replace AXIS Video Motion Detection 3 (VMD3). ![]() When visual confirmation is enabled, colored polygons show which objects the application detects and which objects the application ignores.ĪXIS Video Motion Detection 4 (VMD4) with dynamic background filter and support for three include areas now replaces the built-in motion detection. When the application is configured using the Axis product web pages, visual confirmation can be used to help understand the effect of the different filters. If the event is used to start a recording, it is recommended to configure the pre-trigger time in the recording setup so that the recording also includes the time the object moved in the scene before being detected. That is, all events will be delayed by the set time. For example, when using the Short-lived Object Filter parameter, events will be sent if the object is still moving when the set time has passed. When using ignore filters, events will not be emitted until the filter conditions have been fulfilled. If the object is reported as detected, an event is emitted. When there are moving objects in the camera’s field of view, the application tests the object’s position, size and movements against the include area, exclude areas and filter conditions to determine if the object should be reported as detected or ignored. Ignore filters are used to avoid detecting objects such as shadows of swaying trees, lights from passing cars and small animals regardless of where in the scene the objects appear. Include and exclude areas define the parts of the scene in which moving objects should be detected. The application can be configured by modifying the include area and, optionally, exclude areas and ignore filters. In products with older firmware, the application must first be uploaded and then started. A client application that listens to events from AXIS Video Motion Detection 4 can use the event to, for example, record video or send a notification.ĪXIS Video Motion Detection 4 is preinstalled in products with firmware 6.50 and later but must be started before it can be used. When a moving object is detected, AXIS Video Motion Detection 4 sends an alarm (event). AXIS Video Motion Detection 4 is an AXIS Camera Application Platform (ACAP) application that detects moving objects in the camera’s field of view. ![]()
