6.0 Trigger Event Configuration
6.1 Overview
The camera normally captures and processes images continuously and displays them on the web.
The camera can also be configured to trigger on certain events, and save a set of images around
that trigger time. After a trigger occurs, the camera processes the image sequence to JPEG files
and saves the images either to internal memory or to an external FTP server. The camera can also
send an e-mail to notify a user that a trigger event occurred. A trigger event can be initiated either
through hardware, such as when an infrared motion sensor activates, or by software, such as with
a timer or when a user manually forces a trigger event, or motion is detected in the field of view.
Hardware initiated trigger events involve an external device. Each time the device activates, it
can initiate a trigger event. The camera also has a built-in relay, or output switch, that can control
external devices. Refer to the Reference Manual for information on controlling sensors and other
devices with the camera. Software initiated trigger events force the camera to save image
sequences at specified times or intervals. Specify the interval with the Periodic Triggering
setting.
6.1.2 Using Motion as a Trigger
The camera software includes a motion-detection algorithm that allows it to use motion within
the camera's field of view to initiate a trigger event. After configuring trigger actions in this
chapter and enabling Motion Detection triggers, continue to the Motion-Detection Configuration
chapter to set the motion detection characteristics.
6.2 Trigger Settings
The browser-based Trigger Settings page contains all of the necessary settings for properly
configuring trigger events. To navigate to the Trigger Settings page, either select Trigger Settings
from the navigational pull-down menu located on the View Images page, or click the Trigger tab
that appears in the settings menu. Use the management/superuser login to configure triggers.
After selection, the Trigger Settings page appears.
