Alarm Setup
In the main menu, from Setting to Alarm, user can see alarm setup interface. See Figure 5-58.
Alarm in: Here is for user to select channel number.
Event type: There are four types. Local input/network input/IPC external/IPC offline alarm.
Local input alarm: The alarm signal system detects from the alarm input port.
Network input alarm: It is the alarm signal from the network.
IPC external alarm: It is the on-off alarm signal from the front-end device and can
activate the local NVR.
IPC offline alarm: Once user select this item, system can generate an alarm when the
front-end IPC disconnects with the local NVR. The alarm can activate record, PTZ, snap
and etc. The alarm can last until the IPC and the NVR connection resumes.
Enable: Please user need to highlight this button to enable current function.
Type: normal open or normal close.
Period: It is to set local alarm period. System only enables local alarm in the specified period.
Click the Set button; user can select the business day and the non-business day. Please note
for the work day/free day setup and the specific work day setup, system just saves the latest
setup. For example, the work day ranges from 8:30-17:30 Monday to Friday, and then user
set the period 7:10-18:00 for Monday. So, the arm period of the Monday ranges from 7:10 to
18:00. Please highlight the corresponding button to enable this function.
PTZ activation: When an alarm occurred, system can activate the PTZ operation. The PTZ
activation lasts an anti-dither period.
In the Pan/Tilt/Zoom interface (Main menu->Setting-> Pan/Tilt/Zoom), please set video
channel, speed dome protocol and etc.
Select the channel of current speed dome as current monitor video and the right click
mouse to select Pan/Tilt/Zoom item. Now user can set preset, tour pattern.
In Figure 5-58, click “select” button, user can see an interface is shown as in Figure 5-59.
Here user can set the activation operation such as preset tour, pattern and enable.
Anti-dither: Here user can set anti-dither time. The value ranges from 5 to 600s. The
anti-dither time refers to the alarm signal lasts time. It can be seem as the alarm signal
activation stays such as the buzzer, tour, PTZ activation, snapshot, channel record. The stay
time here does not include the latch time. During the alarm process, the alarm signal can
begin an anti-dither time if system detects the local alarm again. The screen prompt, alarm
upload, email and etc will not be activated. For example, if user set the anti-dither time as 10
second, user can see the each activation may last 10s if the local alarm is activated. During
the process, if system detects another local alarm signal at the fifth second, the buzzer, tour,
PTZ activation, snapshot, record channel will begin another 10s while the 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. User 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 user 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 user disable the alarm event
function directly.
