screen prompt, alarm upload, email will not be activated again. After 10s, if system detects another
alarm signal, it can generate an alarm since the anti-dither time is out.
Alarm output: The number here is the device alarm output port. You can select the corresponding
ports(s) so that system can activate the corresponding alarm device(s) when an alarm occurred.
Latch: When the anti-dither time ended, the channel alarm you select in the alarm output may last
the specified period. The value ranges from 1 to 300 seconds. This function is not for other alarm
activation operations. The latch is still valid even you disable the alarm event function directly.
Show message: System can pop up a message to alarm you in the local host screen if you enabled
this function.
Alarm upload: System can upload the alarm signal to the network (including alarm centre and the
WEB) if you enabled current function. System only uploads the alarm channel status. You can go
to the WEB and then go to the Alarm interface to set alarm event and alarm operation. Please go
to the Network interface to set alarm centre information.
Send email: System can send out the alarm signal via the email to alert you when alarm occurs.
Once you enable the snap function, system can also send out an image as the attachment. Please
go to the Main Menu->Setting ->Network->Email interface to set.
Record channel: you can select proper channel to record alarm video (Multiple choices).
You need to set alarm record mode as Schedule in Record interface (Main
Menu->Advanced->Record). Please note the manual record has the highest priority. System
record all the time no matter there is an alarm or not if you select Manual mode.
Now you can go to the Schedule interface (Main Menu->Setting->Schedule) to set the record
type, corresponding channel number, week and date. You can select the record
type:Regular/MD/Alarm/MD&Alarm. Please note, you can not select the MD&Alarm and MD(or
Alarm) at the same time.
Now you can go to the Encode interface to select the alarm record and set the encode
parameter (Main Menu->Setting->Encode).
Finally, you can set the alarm input as the local alarm and then select the record channel. The
select channel begins alarm record when an alarm occurred. Please note system begins the
alarm record instead of the MD record if the local alarm and MD event occurred at the same
time.
Tour: Here you can enable tour function when an alarm occurs. System supports 1/8-window tour.
Please go to chapter4.7.4.2 Display for tour interval setup. Please note the tour setup here has
higher priority than the tour setup you set in the Display interface. Once there two tours are both
enabled, system can enable the alarm tour as you set here when an alarm occurred. If there is no
alarm, system implements the tour setup in the Display interface.
