Note: Normally, the range of the Pre-trigger buffer is 1-20 frames. This range will change
accordingly if the MJPEG frame rate on the Video frame rate page is 6 or slower.
With the Post-trigger function, users can set a certain amount of images to be uploaded after
the triggering of the alarm input.
Important: Uploading images by FTP or e-mail is only possible if MJPEG output is
configured. If only H.264 streaming is enabled, no images will be sent.
Continue image upload
If selected you can choose to upload the triggered images for a certain time or to keep
uploading until the trigger is off.
● Upload for n sec
The number of frames per second (fps) selected in the Image Frequence list is sent to the
FTP Server for the number of seconds specified in the Upload for n sec box. The range is 1
to 99999 seconds.
● Upload during trigger active
The number of frames per second (fps) selected in the Image Frequence list is sent to the
FTP Server until the trigger is no longer active. The range is 1 to 15 frames.
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.
For a description of these functions, see chapter PTZ&IMAGE.
If the selected function is Preset, the dwell time (1-256 sec.) must be specified in the Dwell
time box. When the alarm is triggered, the camera will go to the selected Preset Point and
stay there for the user-defined period of time. As for other function modes, the camera will
keep executing the specified function. To stop this action, simply change the camera status.
Note: The dwell time can only be adjusted when Preset is selected as the alarm action.
When the dwell time has expired, the camera will go back to its trigger position and recheck
the alarm pin status.
Record video clip
Using the options on the Record to list, you can have an alarm-triggered recording saved to
your microSD card or NAS. The Pre-trigger buffer function allows you to check what
occurrence caused the trigger. The Pre-trigger buffer time range is from 1 to 3 seconds.
You can choose from the following actions:
● Upload for n sec
The image stream is recorded for the number of seconds (setting range from 1 to 99999
seconds) specified in the Upload for n sec text box with a pre-trigger buffer of the number
of seconds specified in the Pre-trigger buffer text box.
● Upload during trigger active
The image stream is recorded with a pre-trigger buffer of the number of seconds specified
in the Pre-trigger buffer text box until the trigger is no longer active.
Note: Make sure that local recording (with the microSD card) or remote recording (with
NAS) is activated (on the Recording page) so that this function can be implemented.
Send message by E-mail
A message is sent by email, as configured on the Mail page, when an alarm is triggered. For
more information on configuring messages to be sent via SMTP, see setion Mail.
