2.3 Connecting Devices to the Unit
This section lists some important notices that should be read before making
any connection to the DVR series unit.
Connecting Required Devices
Before power up the unit, you should connect cameras and a main monitor to
the unit for basic operation. If needed, connect a call monitor for displaying
full screen video of all installed cameras in sequence.
Connecting Short-term Device
If you plan to install any short-term devices to the DVR series unit and use
them as part of the unit system, such as USB CD-ROM, USB Hard Disk Drive,
etc, make sure those devices are connected only after the unit is powered up.
The reason is because the DVR series unit can recognize the external
devices only after the power-up process is done completely.
