spill any liquid on the unit.
•
Do not use units intended for indoor applications near water, in damp or wet environments, or in
any area classified as a wet location. Do not expose an indoor unit to rain or moisture to reduce
the risk of fire or electric shock.
•
Do not block or cover any openings in the unit enclosure. These openings are provided for
ventilation to prevent overheating and to ensure reliable operation. Ensure the unit is placed in
an area with adequate ventilation.
•
Do not place the unit near a heat source such as heaters, stoves, radiators or other equipment
that produces heat.
•
Use the following guidelines if placing the unit in a rack-mount:
• The ambient temperature of a rack-mount environment may exceed the recommended
operating temperature of the unit. Take care to read the ambient temperature before
installation.
• A rack-mount environment may restrict the movement of air. Ensure the unit receives the
proper amount of air flow required for safe operation or install the unit elsewhere.
• A rack mount is capable of supporting a maximum weight. Ensure the rack mount can support
the additional weight of this unit.
• A rack mount environment requires proper and adequate circuitry. Ensure the circuits to the
rack are capable of handling the electrical requirements of all units in the rack to protect
against circuit overloads.
•
Pack the unit with standard factory packaging or material of the same quality when transporting
the unit.
•
Take care to avoid heavy stress, violent vibration, or water spills to the camera unit during

Opening the unit may cause water leakage or expose components to direct light. Contact the
manufacturer or a qualified service representative to service the camera or to replace a

Dahua recommends the use of a thunder-proof device in concert with the unit.
•
Use a dry soft cloth to clean the unit's housing. If the unit is particularly dusty, use water to dilute
a mild detergent, apply the diluted detergent to a soft cloth, then gently clean the device. Finally,
use a dry cloth to wipe the unit dry. Do not use a volatile solvent like alcohol, benzene, or thinner;
or use a strong detergent with abrasives, which may damage the surface coating or reduce the
working performance of the unit.
