Replace camera option
We can replace new found cameras by cameras that are already added to the NVVR device easily. This action is
usually performed when a camera stops working and we want to replace it but keeping all its recordings and
configuration. When a camera replaces another one, the old recordings, scheduling and all the settings related to
the replaced camera are assigned to the new one.
An example of this process is shown in the screenshot below.
WARNING
If the IP address is changed at the same time that the camera is added to the system, the process may fail.
In that case, Nethunter will prompt a message and the “Show new cameras” option must be executed again and the IP camera added again. This time
it will have the IP already changed.
When a new camera is added, if the ip address is changed,a “ping” network command is performed to the new ip address for checking the status. If
the ip camera does not reply , the NVVR will not add it.
Likewise, if the ip address of any camera on the NVVR is changed, a “ping” network command is performed to the new ip address for checking the
status. If the ip camera does not reply, the changed is not accomplished.
NOTE
MJPEG codec is not supported by Nethunter system. Please, set all the cameras codec to either MPEG-4 or H.264.
NOTE
The first stream is used by the NVVR to broadcast Live images. The secondary stream is used by the NVVR to record images.
NOTE
From version v2.5 on, the NVVR is recording a fixed to 10 seconds post-alarm. It is not configurable.
WARNING
If the setting “Second stream enabled” is checked, the camera or the NVVR have to be restarted in order to take effect.
This functionality is only supported by UDPTech cameras and Axis cameras with firmware v5.
The cameras configured as dual-streaming are shown as “Connected” in Monitor only when both streams are connected properly.
On Axis cameras, the secondary stream is the profile named as "Quality". If this profile is not present on the camera, admins must create it. Otherwise
the connection to the secondary stream will fail.
WARNING
Only when the setting “Alarm ports enabled” is checked, the NVVR will get the events from that camera. It’s recommended to leave this setting
checked. In addition, check that the alarms port is enabled on the camera.
