Scene Change
After a System Administrator has rearmed an alarm produced by the
Scene Change-type of tamper detection, move the camera back to the scene that the
organization needs to monitor.
The Blind type of tamper detection can be used for fixed and for PTZ cameras.
Blur and Scene Change tamper detection are designed for fixed cameras only, not for
PTZ use. Using pan, tilt or zoom functions will trigger Blur and Scene Change.
Scene Change is sensitive to large scale changes in a scene. For example, using Scene
Change for a camera that shows many chairs in a row, close by, such as in an airport or
casino, may not be effective. If the DVR learns while people are sitting, that sitting persons
are not to be considered as sabotage, when the chairs empty, the scene may have
changed enough for the DVR to trigger a log entry or an alarm. And if the operator makes
the DVR learn when the chairs are empty, then tamper detection may be triggered when
people sit in the chairs. The same can be said for a row of vehicles that are frequently
moved, such as in a taxi stand or truck depot.
Rapid Eye sessions (live, retrieval and alarm) are sent to port 10 000, the DVR base IP port.
The value of the base port can be changed by a System Administrator. For port functions,
