2.3 Connecting Devices to the Unit
This section lists some important notices that should be read before
making any connections to the MPEG-4 DVR.
NOTE: Connect short-term devices, such as USB ThumbDrive ® ,
USB CD-ROM, USB Hard Disk Drive, etc., only after the unit is
successfully powered up.
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 MPEG-4 DVR 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. Because MPEG-4 DVR can recognize the external devices
only after the power-up process is done completely.
