Out port setting includes the following settings:
OFF/ON: Determine whether or not an alarm is to be output.
Output value: Determine whether the High or Low signal will be output
when an alarm occurs. Enter the time for continuous signal output
of selected output value (High or Low) in the text box below.
Example: High 100ms
The High signal will be output for 100ms. After that, the output
value will change to Low.
Initialization: Determine whether or not the alarm signal will be output
one time when the power is turned on.
❉ Set the values of Out port setting in accordance with the device to
which the output is to be sent.
Retry is used to set the number of times the clients (V.Networks controllers) are
notified of the occurrence of an alarm input. (The number of times can be set to 1, 2,
or 3.)
In a LAN environment, Alarm notifications may fail. It is for that reason that the alarm
notification count can be set to up to 3 times. However, even when the alarm
notification count is set to more than 1, the specified operation performed by the
clients (V.Networks controllers) is only once.
In Alarm force output, pressing the Output button causes the camera's alarm output
terminal to output a signal according to the current alarm output port setup. This
function can be used to check the devices connected to the output port.
