In Detect interface, copy/paste function is only valid for the same type, which means you
can not copy a channel setup in video loss mode to tampering mode.
About Default function. Since detection channel and detection type may not be the same,
system can only restore default setup of current detect type. For example, if you click
Default button at the tampering interface, you can only restore default tampering setup. It
is null for other detect types.
System only enables tampering function during the period you set here. It is null for

Before operation, make sure you have properly connected alarm devices such as buzzer.
In the main menu, from Setting->Event->Alarm, you can see alarm setup interface.
For analog channel, the interface is shown as in Figure 4-88 and Figure 4-89 .
For digital channel, there are four alarm types. See Figure 4-88 to Figure 4-91.
Local alarm: The alarm signal system detects from the alarm input port.
Network 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 HDVR.
IPC offline alarm: Once you select this item, system can generate an alarm when the front-
end IPC disconnects with the local HDVR. The alarm can activate record, PTZ, snap and etc.
The alarm can last until the IPC and the HDVR connection resumes.
Important
If it is your first time to boot up the device, the disconnection status of the
front-end network camera will not be regarded as offline. After one
successfully connection, all the disconnection events will be regarded as IPC
offline event.
When IPC offline alarm occurs, the record and snapshot function of digital
channel is null.
