Check the [Alarm input] box to enable the camera's alarm input or uncheck this box to
disable it.
Trigger condition: select a voltage level at the camera alarm input:
High: if this option is selected, the camera determines that an event has occurred when
a 12 V power source is connected to the input pins, i.e. an alarm is generated when the
voltage increases from 0 to 12 V.
Low: if this option is selected, the camera determines that an event has occurred when
a 12 V power source is disconnected from the input pins, i.e. an alarm is generated
when the voltage decreases from 12 to 0 V.
IMPORTANT:
If use the input alarm contacts together with the output alarm contacts, you need to connect them to
separate power sources. If the contacts are connected to the same power source, they may work
incorrectly. For example, it may cause false triggering.
