Trigger an alarm signal when the HDD is about to be out of operation or is otherwise experiencing
drive health issues. Please refer to “4.1.4 HDD” to check the HDD status.
VIDEO LOSS
Trigger an alarm signal when a camera signal is suddenly disconnected.
DISK ERROR
Trigger an alarm signal when the system does not record images due to an error in HDD.
DISK FULL
Trigger an alarm signal when the HDD is occupied with a certain percentage of its capacity. If the
user sets HDD FULL as STOP RECORDING and the HDD is occupied with the certain percentage set
here, NVR stops recording and the alarm trigger.
The extra alarm will appear in the event log only when it is set as “ON”.

RELAY: Select related output. The NVR will output a signal through the selected relay output port
(RS-485).
Relay contacts can bear up to 24V 1A other devices. If it is connected to a power source
of more than 24V 1A, the system may have a problem with it.
