Note
The key in the virtual keyboard includes often used words, such as Admin,
root, http://, rtsp://, www., .com, .net, .org etc.
3.2 Camera Registration
The NVR can connect to any ONVIF® IP cameras over the network. If the cameras are connected to
the PoE switch in the back of the NVR, the cameras will also receive power and send data to and from
the NVR.
Note
As part of the cybersecurity settings of the NVR, the VMAX IP G4 will assign passwords
automatically to new DW IP cameras that are added with a blank password. If a camera is
added to the NVR for the first time, without having its password set from the IP Finder™, the
NVR will automatically assign it a new password. If the camera then needs to be connected
to another NVR or system, users will need to reset the camera’s settings.
PoE Camera Connection
PoE cameras are automatically connected when the camera is plugged into the PoE port. Channels
assigned to cameras connected directly to the NVR’s PoE switch will display the channel title in green.
Cameras connected to the NVR’s PoE switch must be set to ‘DHCP’ before being connected to the NVR.
For cameras that support ‘Auto IP’, the NVR will automatically control its IP settings.
Note
If a PoE camera is connected to the PoE channel where another camera has already been
virtually assigned to that channel, the virtually assigned camera will be moved to another
channel and the PoE camera will be assigned to that channel.
Note
Zero-Configuration is the Link-Local IP address assignment method through Auto-IP
and is for automatically assigning IP addresses when DHCP is otherwise not available
or supported. The device that adopts this technology selects an IP of
169.254.xxx.xxx and assigns the IP address after checking the availability of the
selected IP address.
