Devices & DLKs
You must have a Device License Key (DLK) for every device (IP network camera or IP video server)
installed on your NetDVMS surveillance system.
Remember that you are allowed to install and use only the number of cameras listed on your
organization's license sheet; regardless of you number of available DLKs. For example, a fully used
four-port video encoder counts as four cameras even though the cameras are connected through a
single device—therefore a fully used four-port video encoder will use four licenses.
System administrators obtain DLKs as part of the software registration process.
You are able to specify each DLK manually when
adding a device
through the Device Setup Wizard,
available by clicking the Add Device... button in the
Administrator window
. However, you can avoid
having to specify each DLK manually by using the following procedure to import all received DLKs into
NetDVMS in one go:
Prerequisites: The DLKs, received in a .dlk file, must have been saved at a location accessible by the
surveillance server, for example on a network drive or on a USB stick.
1.
Open the
Administrator window
.
2.
In the Administrator window, click the Import DLKs... button.
3.
Browse to the location at which you have saved the received .dlk file.
Select the file, and click Open.
All DLKs are now automatically imported, and the relevant DLK will automatically appear when
you
add a device
through the Device Setup Wizard.
How To Add A Device
In NetDVMS you add devices (IP video camera devices, IP video encoder devices or digital video
recorder (DVR) devices) rather than actual cameras. This is because devices have their own IP
addresses or host names. Being IP-based, NetDVMS primarily identifies units on the surveillance
system based on their IP addresses or host names.
Even though each device has its own IP address or host name, several cameras can be attached to a
single device and thus share the same IP address or host name. This is typically the case with
cameras attached to video encoder devices or DVR devices.
You can of course configure and use each
camera individually, even when several cameras are attached to a single device.
In addition to camera devices, video encoder devices and DVR devices, it is possible to add a number
of dedicated I/O (input/output) devices to NetDVMS. When such I/O devices are added, they can be
used in events-based system setup in the same way as a camera. For more information about using
I/O devices, see
Using Dedicated I/O Devices
. For information about which I/O devices are supported,
refer to the release note.
Once a device is added in NetDVMS, any cameras attached to the device are automatically recognized
by the software, and listed in the Administrator window's Device Manager section:
