On the other hand, <Post-trigger buffer> is for users to upload certain amount of
images after alarm input is triggered.
Check the box <Continue image upload> to upload the triggered images during
certain time or keep uploading until the trigger is off. Select <Upload for __sec>
and enter the duration in the blank. The images of the duration will be uploading
by E-mail when the alarm input is triggered. The setting range is from 1 to 9999
seconds. Select <Upload during the trigger active> to make the images keep
being uploaded to E-mail during the trigger active until the alarm is released. Set
the Image frequency as the upload frame rate. The setting range is from 1 frame
to 15 frames.

section Mail for further details.
z PTZ Function
Assign a camera function: Preset, Sequence, Autopan or Cruise, and specify a
Preset Point / Sequence Line / Autopan Path / Cruise Line for the camera to
perform at an alarm occurrence.
NOTE: Please refer to the sections through Preset Programming to Sequence
Line Programming for details of Preset Point / Cruise Line / Autopan Path /
Sequence Line setups.
If the selected function is <Preset>, it is required to enter its dwell time (1 ~ 256
sec.) in the corresponding field as shown below. When the alarm is triggered, the
camera will go to the selected Preset Point and stay there for a user-defined
period of time. As for other function modes, the camera will keep executing the
specified function; to stop the performance, simply change the camera’s status.
NOTE: The dwell time is only adjustable when selecting Preset as the alarm
action. When the dwell time is up, the Camera will go back to its trigger position
and recheck alarm pin status.
z Send HTTP notification
Check this item, select the destination HTTP address, and specify the parameters
for event notifications by <Alarm> triggered. When an alarm is triggered, the
notification can be sent to the specified HTTP server.
