9.2.8.3 Network Failure Detection
The Network Failure Detection setting can be found under this path: System>
Events> Network Failure Detection .
Network Failure Detection allows the camera to ping another IP device (e.g.
NVR, VSS, Video Server, etc.) within the network periodically and generates
some actions in case of network failure occurs, for instance, a Video Server is
somehow disconnected.
Being capable of implementing local recording (through SD card) or remote
recording (via NAS) when network failure happens, the camera can be a backup
recording device for the surveillance system.
Detection Switch
The default setting for the Detection Switch function is <Off>. Enable the
function by selecting <On>
.
Users can also activate the function according to
the schedule time that is previously set in the <Schedule> setting page.
Select <By schedule> and click <Please
select…> to choose the desired
schedule from the drop-down menu.
Detection Type
Input the IP device address and the period of ping time to ping. The camera will
ping the IP device every N minute(s). If it fails up to three times , the alarm will
be triggered automatically. The ping time setting range is from 1 to 99 minutes.
