AXIS 250S User's Manual
Trigger Type
The trigger type is what starts the event type. The following options are available:
• Input Ports - This describes the states that the 4 inputs must be in before the event is
triggered. One or more inputs can be used together, but note that the states for all the
inputs used must first be reached before the event is triggered.
• Timer - whole time frame - This option will simply use the times specified in Respond to
Trigger... described above.
• Timer - periodically - Use this to trigger the event at a certain frequency. Configurable in
seconds, minutes or hours. It is also possible to specify the time to commence triggering.
Note that this setting also uses the times specified in Respond to Trigger...
• Loss of Video - If the video signal disappears, this will trigger the event. A notification of
the event would be a suitable action for this trigger. If the event type has been configured
to upload a video sequence for this trigger, then this will, of necessity, only be the
pre-trigger sequence, if this has been enabled.
• Server Boot - This can be used to trigger the event whenever the server is started or
restarted. A notification of the event would be a suitable action for this trigger type.
• Log Messages - The server can trigger an event whenever a system event writes an entry
to a log file. There are three types of log file; Information, Warning or Critical. Select the
level that will trigger the event. Note that the first two alternatives also include messages
of a higher importance, so alternative 1 will trigger the event type the most, as it also
includes Warning and Critical log messages.
• Manual Trigger - This option makes use of buttons provided on the Live View page, which
are used to start or stop the event manually.
When Triggered...
These settings describe the actions to take when the event type is triggered. One or more
actions may be selected.
• Upload to FTP server - Select the FTP server to upload images to. Note that FTP servers must
first be configured in Upload Servers. See page 23.
• Upload for - Specify the total time to upload the recording. Configurable in seconds,
minutes or hours. This can be used to continue the upload even after the event has ended.
• Upload as long as trigger is active - This option will terminate the upload as soon as the
event ends.
• Split upload into - Use this to split a long video sequence into several shorter sequences.
Configurable in seconds, minutes or hours. This is recommended if there is likely to be
recordings longer than 30 minutes in duration. The AXIS 250S can easily handle video files
of more than 30 minutes, but these may cause problems for some older types of FTP server,
due to the large file sizes involved.
