MENU ITEM DESCRIPTION
Internal Buzzer The multiplexer has an internal buzzer that is activated in
response to an alarm if this setting is set to ON.
Alarm Relay Output There are two alarm output signals available in the external
IO connector: ALARM NO and ALARM NC. These signals
are driven by an on-board relay that can be used to drive a
light or siren to warn the operator of alarm events. The
alarm output pins are enabled/disabled by setting this
parameter ON/OFF.
Alarm Log Used to enable/disable the Alarm History Log. When
enabled, up to 255 events will be logged using non-volatile
memory. The memory architecture is FIFO (First In First
Out), so that the latest 255 events are kept in the list.
Alarm Full Screen When an alarm occurs on any camera input, the
corresponding camera will be displayed on the Main
Monitor in full screen until the alarm duration expires. This
item allows you to enable or disable this function.
