Operation Manual

The <Pre-trigger buffer> recording function allows users to check what happened to trigger the alarm. The pre-
trigger buffer time range is from 1 to 20 frames.
On the other hand, the <Post-trigger buffer> is for uploading a certain amount of images after the alarm input is
triggered. The post-trigger buffer time range is from 1 to 20 frames.
Check the box <Continue image upload> to upload the triggered images during a 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 uploaded to
the FTP when the alarm input is triggered. The setting range is from 1 to 9999 seconds.
- Select <Upload while trigger is active> to keep the images being uploaded to the FTP while the trigger is active,
i.e. until the alarm is stopped.
Set the Image frequency as the upload frame rate. The setting range is from 1 frame to 15 frames.
NOTE: Make sure SMTP or FTP configuration has been completed. See section 9.5. Mail and 9.6. FTP for further
details.
- Send HTTP notification:
Check this item, select the destination HTTP address, and specify the parameters for event notifications when an
<Alarm> is triggered. As soon as an alarm is triggered, the notification will be sent to the specified HTTP server.
For instance, if the custom parameter is set as ”action=1&group=2”, and the HTTP server’s name is
”http://192.168.1.200/admin.php”, the notification will be sent to the HTTP server as
”http://192.168.1.200/admin.php? Action=1&group=2” when an alarm is triggered.
