7.3.10 Network Failure Detection

The network failure detection function allows the IP camera to periodically ping another IP device
within the network to detect a network failure, for example, if a video server is disconnected. By
implementing local recording (through a microSD/SDHC card) if a network failure occurs, the camera
can operate as a backup recording device for the surveillance system.
Detection Switch
The Administrator can enable or disable the detection function by selecting On or Off.
By Schedule
For instructions how to set a schedule for network failure detection, refer to Schedule.
Detection Type
In the text box, enter the IP address to ping and the time interval in minutes between pings.
Triggered Action
The Administrator can specify various alarm actions to be taken when an alarm is triggered. The
options are listed below.

Enable alarm output – Check this box and select the predefined type of alarm output (low or
high) to enable alarm relay when tampering is detected.

Record stream to sd card -– Select this box in order to save the alarm-triggered recording
into a microSD/SDHC card. Enter the number of seconds for the pre-trigger buffer. Select the
first radial button to upload for a specified length of time and enter the number of seconds.
