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

highly recommended.

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.

case, especially to the bottom side of the unit.

space for air ventilation on the unit’s bottom side.

The DVR is designed to operate under either NTSC or PAL video formats.
