Network Failure Detection

Network Failure Detection allows the IP 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 microSD card) when
network failure happens, the IP Camera could 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 ping time
setting range is from 1 to 99 minutes.

is detected. All options are listed as follows.

Record Video Clip

Pre-trigger buffer recording function allows users to check what

1 to 3 seconds. Select <Upload for __ sec> to set the recording duration
after alarm is triggered. The setting range is from 1 to 99999 seconds.
