System Setup
The notices and introduction on system installation will be described
particularly in this chapter. Please follow the description to operate the unit.
In order to prevent the unit from data loss and system damage that caused by
a sudden power fluctuation, use of an Uninterruptible Power Supply (UPS) is
highly recommended
2.1
Position the DVR
First, note to position / mount the DVR in a proper place and be sure to power
off the unit before making any connections. The placed location should avoid
hindering or blocking the unit from airflow.
Enough airflow is needed to
protect the unit from overheating. The maximum allowable temperature of
operating environment is 40°C.
The unit utilizes heat-conducting techniques to transfer internal heat to the
case, especially to the bottom side of the unit.
NOTE:
Be sure the rubber feet are not removed, and always leave a
space for air ventilation on the unit’s bottom side.

Connect Devices to the DVR
This section lists some important notices that should be read before making
any connection to the DVR.
Connecting Required Devices
Before power up the unit, cameras and a monitor should be connected 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 any short-term devices shall be installed to the DVR as parts of the unit
system, such as USB ThumbDrive® or any USB devices, etc, make sure
those devices are connected only after the unit is powered up. The reason is
because the DVR can recognize the external devices only after the power-up
process is done completely.
