Event type: Choose from Local alarm (default) or Net alarm (a Net alarm means the alarm
signal comes from the TCP/IP. You can enable the network alarm function via the net
SDK. The network alarm does not have a 'device type', 'anti-dither' and 'alarm upload'
function. The other items are the same).
Alarm in: Select a specific channel number (or all channels).
Enable: select to activate the alarm function (default is enable)
Type (only used for Local alarm): The event behavior can be configured independently for
each channel:
– N.O. - Normally Open causes an alarm to trigger only when the circuit closes (this is
the default)
– N.C. - Normally Closed causes an alarm to trigger only when the circuit is opened
Period: Click <Setup> for a new interface screen where you can organize time periods for
alarm activation – see Period, page 60.
Anti-dither: Set here how long the alarm signal lasts after it is activated (default is 5
seconds). The alarm signal includes buzzer, tour, PTZ activation, snapshot and channel
record, but does not include the latch time. During the alarm process, the alarm signal
can begin an anti-dither time if the system detects the local alarm again. The screen
prompt, alarm upload, email, etc. will not be activated. For example, if you set the anti-
dither time to 10 seconds, you will see that each activation lasts for 10 seconds if a local
alarm is activated. If the system detects another local alarm signal during this period (e.g.
at the fifth second), the buzzer, tour, PTZ activation, snapshot, record channel will start
