Users can set up rules for what should happen when one or more triggers are met. Usually, the word trigger is sufficient, and the word event can be left out. In newer Axis software and products, we use the term condition instead of trigger.
When a camera is installed in a potentially explosive environment, such as chemical processing plants, or gas pipelines, its housing must meet very specific safety standards. It is the explosive environment that must be protected from potential igniters from the camera and other equipment. If the camera is explosion protected, it means that it will contain any explosion originating within its housing. Sometimes this capability is referred to as explosion-proof.
Focus recall is a feature that allows you to save focus areas to which the PTZ camera automatically returns when it moves into that view. This feature is especially useful in challenging lighting conditions, where the camera would have trouble finding focus. To use focus recall, you click a button when you’re satisfied with the focus of the current view, and the camera creates a focus recall area. Later, the camera automatically recalls the previously set focus for that view.
The frame rate is the frequency at which a video stream is updated. We measure frame rate in frames per second (fps). When there's movement in the video stream, you need a high frame rate to maintain good video quality.
