Field Description
Ftp Server
Port Lets you specify port number to use for sending event information from the
device to the surveillance system via FTP. Default port is port 21.
Alert Port Lets you specify port number to use for handling event-based alerts, including
generic events . Default port is port 1234.
SMTP Port Lets you specify port number to use for sending event information from the
device to the surveillance system via SMTP. Default port is port 25.
Polling
Frequency
[1/10 sec] For a small number of devices, primarily I/O devices (see Using Dedicated I/O
Devices ), it is necessary for the surveillance system to regularly check the
state of the devices' input ports in order to detect whether input has been
received.
Such state checking at regular intervals is called
polling . The Polling
Frequency field lets you specify the interval between state checks.
Interval is specified in tenths of a second. Default value is 10 tenths of a
second (i.e. one second).
For I/O devices it is highly recommended that the polling frequency is set to
the lowest possible value (one tenth of a second between state checks).
For information about which devices require polling, see the release note.
