AXIS Q1755 - Event

Examples:

• Avoid triggering on small objects in the video image by setting the object si

ze level to high.

• Use several small Motion Detection windows rather than one large window, if triggers on small movements or

objects are desired.

• To reduce the number of triggers if there is a lot of movement during a short period of time, select a high history

level.

• To only detect flashing light, select low sensitivity. In other cases, a high sensitivity level is recommended.

Port Status

Under Setup > Events > Port Status there is a list showing the status for the camera’s input and output. This is for the

benefit of Operators who have no access to the System Options section.

Example: If the Normal state for a push button connected to an input is set to Ope

n circuit - as long as the button is not

pushed, the state is inactive. If the button is pushed, the state of the input changes to active.
