failover
This function is only available for products that support failover. To find products that support this, see “
nvr
products supporting each feature
”. (Product Specification Manual, page 4)
Functions allowing other devices in a ready-state to perform recording if the NVR device can't perform
recording due to network error.
You can connect 32 “Normal” devices to one “Standby” device.
M
`
For a device to be configured for troubleshooting, both the camera and the viewer port must be connected to the local network.
`
All devices should be the same model when performing troubleshooting.
`
Troubleshooting network interface supports IPv4 only.
`
The time of all devices should be synchronized. For time sync setup, see the "
Menu Setup
>
System Setup
" page in the
Table of Contents.
`
The network IP bandwidth should be set differently in the NVR.
-
Example of IP in a different bandwidth
Example 1
) IP : 192.168.1.200, subnet 255.255.255.0
In the Example 1) above, since 255 of the subnet corresponds to 192.168.1, any IP in a format of
192.168.1.x has the same bandwidth.
An IP in a format of 192.168.2.x has a different bandwidth with an IP in a format of 192.168.1.x.
Example 2
) IP : 172.16.1.200, subnet 255.255.0.0
In the Example 2) above, since 255 of the subnet corresponds to 172.16, any IP in a format of 172.16.x.x
has the same bandwidth.
An IP in a format of 172.17.x.x has a different bandwidth with an IP in a format of 172.16.x.x.

to set troubleshooting
1.
Set a device to 'Standby' and set the rest of the devices to 'Normal' mode.
2.
Enter the viewer port ID and administrator's password of a 'Standby' device that you wish to connect from
a device set to a normal mode, and press the <
connection
> button under the status bar.
3.
Check the IP and status of the 'Normal' devices connected to the 'Standby' device.
menu > network > failover
•
Mode : Select either <
normal
> or <
Standby
> mode.
- Normal : Device in recording operation. It is monitored by the Standby device.
- Standby : Device that is in a ready-state, not performing the recording operation. It performs the recording
operation instead of the Normal device that is out of order.
in the case of normal mode
•
Standby IP (All) : Enter the viewer port ID of a standby device to access.
•
Standby Password : Enter the administrator password of the standby device.
•
Status : Displays the current connection status.
•
Access or Disconnect button : Click the button to access or disconnect the access.
in the case of standby mode
•
Device list/Status: Shows the current state of the normal device(s) connected to the standby device. To delete
a connected normal device, click the <
delete
> button on the right side of the device.
M
`
For a Standby device, you can only use limited functions in the <
System Environment
>, <
Device
> and <
Network
>
menus. You can't use the <
Record
> and <
Event
> menus.
`
Activating the troubleshooting operation while playing a video or backing up a section in the Standby device will stop the
previous operation and a live image will be displayed.

Normal and standby are connected (troubleshooting mode available)
Failover
Troubleshooting is being performed
Connected fail
Connection was attempted but failed
Authentication failure
Authentication failed due to incorrect standby password when attempting
connection
Connected(Match Time Required)
Connected but not time synchronized with the standby equipment
Connected(check camera port IP)
Situation in which the IP bandwidth of the camera port does not match even in a
case of connecting from the camera port of a normal device to the viewer port of a
standby device or to the port of the same viewer
Connected fail(check camera port IP)
Situation in which connection from the camera port of a normal device to the camera
port of a standby device has been attempted, but it failed to establish connection
Connected fail (It is a different model.)
Attempted to establish a connection between different models but failed to establish
connection
