everyday. The snapshot interval is set in "Snapshot every seconds".
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. Network Camera will continuously monitor the channel and digital input every half
second. Once the user-defined conditions are matched, Network Cameras 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. "Automatically restore DO state after
seconds" allows you to restore DO state after events trigger DO
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 Network Camera to detect varied images. Once the
"Trigger condition" is matched, Network Camera 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.
