The other "Event operation" can be used to combine motion detection with devices attached to digital
input, to drive devices attached to digital output, or send out snapshots for evidence. It helps users
establish an easy security system. Administrators may choose any combination of conditions to form
special applications according to their personal needs. NetworKam will continuously monitor the channel
and digital input every half second. Once the user-defined conditions are matched, NetworKams will
capture three stages of events and react based on the "Trigger action" settings. The post-event snapshot
can be configured to be delayed after events happen according to the setting in "Take snapshot at
seconds after event". The three stages of snapshots will be VPRE.JPG, VTRG.JPG and VPOS.JPG. Since
the same event may exist for a while, administrators can set delay time in "Delay seconds before
detecting next event" to reduce multiple triggers by the same event.
There are two kinds of "Trigger condition". For digital input there are four options provided to combine
with the user's device. Rising and falling will make events happen once. For motion detection, there are
window names shown below as choices. Refer to the previous section for configuring motion detection.
Note that larger object size and lower sensitivity will make it more difficult for NetworKam to detect
varied images. Once the "Trigger condition" is matched, NetworKam will drive the digital output device
and/or upload snapshots based on the "Trigger action" settings. The application settings should be
carefully examined to operate accurately. If administrators are not sure of the digital output status before
configuring applications, "Reset output" can be used to return the digital output to the default "Normal
Close" state.
