Physical installation 
This section describes how to install the recorder. 
Installation environment 
When installing your product, consider these factors: 
•  Ventilation 
•  Temperature 
•  Moisture 
•  Chassis load 
Ventilation: Do not block any ventilation openings. Install in accordance with the 
manufacturer’s instructions. Ensure that the location planned for the installation of the 
unit is well ventilated. 
Temperature: Consider the unit’s operating temperature (-10 to +55 ºC, 14 to 131 °F) 
and noncondensing humidity specifications (10 to 90%) before choosing an installation 
location. Extremes of heat or cold beyond the specified operating temperature limits 
may reduce the life expectancy of the recorder. Do not install the unit on top of other 
hot equipment. Leave 44 mm (1.75 in.) of space between rack-mounted DVR units. 
Moisture: Do not use the unit near water. Moisture can damage the internal 
components. To reduce the risk of fire or electric shock, do not expose this unit to rain 
or moisture. 
Chassis: Equipment weighing less than 15.9 kg (35 lb.) may be placed on top of the 
unit. 
Unpacking the recorder and its accessories 
When you receive the product, check the package and contents for damage, and verify 
that all items are included. There is an item list included in the package. If any of the 
items are damaged or missing, please contact your local supplier.
