2. 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.
2.2 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.
