Events and Event Types
The AXIS 250S MPEG-2 Video Server is capable of performing various actions when
certain types of events occur. The terminology used to describe this is as follows:
•
Event type
- a defined set of parameters that specify how and when something will
trigger an action.
•
Event
- an event that occurs while the system is running. It is started by a trigger, it
initiates an action, and is time-stamped and named.
•
Action
- what occurs when the event triggers. Examples are the upload of video to an
FTP server, email notification, etc.
•
Trigger
- the circumstances that start an event. This could be e.g. a pre-programmed
time or a signal from an external device, such as a door switch or a motion sensor.
Configuring Event Types
An event type is a set of parameters describing how and when the server will perform
certain actions. An event type may result in one single event, or it may result in many,
depending on how often is triggered. The most common kind of event type will trigger the
upload of images to a specified destination. Other actions performed by event types can
include the sending of e-mail, the activation of the output port and various types of event
notification.
Important!
• Event types that perform uploads should be kept to the minimum required for your application. There
is a limit of 3 simultaneous uploads at any one time, although more may be configured.
• Note that when adding, modifying and deleting event types, any other event type that is currently
active will be stopped. Stopped event types that have been configured to run for as long as the trig-
ger is active will automatically restart, but others with different configurations will not.
