AXIS Q1755/-E - Events
Examples:
• Avoid triggering on small objects in the video image by setting the object size 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 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 Open 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.
