This manual offers reference material and general information about the basic operation,
maintenance, and troubleshooting of the Dahua HCDVI Digital Video Recorder. Read, follow, and
retain the following safety instructions. Heed all warnings on the unit and in the operating instructions
before operating the unit. Keep this guide for future reference.
1.1 Important Safeguards and Warnings
Electrical safety
• Install the unit in accordance with the manufacture r’s instructions and in accordance with
applicable local codes.
• All installation and operation must conform to your local el ect rical safety codes.
• Do not overload outlets and extension cords, which may cause fire or electrical shock.
• Do not place the camera near or in a place where the camera may contact overhead power lines,
power circuits, or electrical lights.
• Ensure power conforms to SELV (Safety Extra Low V oltage) and that the limited power source is
rated AC 24V as specified in IEC60950-1. (Power supply requirement is subject to the device
label).
• All input/output ports are SELV circuits. Ensure that SELV circuits are connected only to other
SELV circuits.
• Ground the unit using the ground connection of the power supply to protect the unit from damage,
especially in damp environments.
• Protect the plug and power cord from foot traffic, being pinched, and its exit from the unit.
• Units with or without an ON/OFF switch have power supplied to the unit whenever the power
cord is inserted into the power source; however, the uni t is operational only when the ON/OFF
switch is in the ON position. The power cord is the main pow er disconnect device for switching
off the voltage for all units.
• Operate the unit only from the type of power source indicated on the label. Before proceeding,
disconnect the power from the cable to be installed into t he unit.
• For external power supplied units, use only the reco mm ended or approved power supplies.
• Limited power sources must comply with EN 60950. Substitutions may damage the unit or
cause fire or shock.
• For 24 VAC units, voltage applied to the unit’s input power sh oul d not exceed ±25%. User-
supplied wiring must comply with local codes (Class 2 power levels). Do not ground the
supply at the terminals or at the unit’s power supply t ermi nal .
• Contact the local dealer or the power company to verify the correct power supply.
• Do not attempt to service the unit. Opening or removi ng cov ers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified personnel.
• If the unit is damaged and requires service, unplug the unit from the main power supply and refer
to qualified service personnel. Damage may includ e, but is not limited to:
• The power supply cord or plug is damaged.
• Liquid has spilled in or on the unit.
• An object has fallen on the unit.
• The unit has been dropped and the housing is damaged.
• The unit displays a marked change in performance.
• The unit does not operate in the expected manner when t he user correctly follows the proper
operating procedures.
• Ensure a service technician uses replacement pa rt s specified by the manufacturer, or that have
the same characteristics as the original parts. Unauthorized parts may cause fire, electrical
shock, or other hazards. Dahua is not liable for any damage or harm cau sed by unauthorized
modifications or repairs.
• Perform safety checks after completion of service or repairs to the unit.
• Use attachments and accessories only specified by the m anuf acturer. Any change or
modification of the equipment, not expressly approved by Dahua, could void the warranty.

• Incorporate a readily accessible disconnect device in the building installation wiring for quick
power disconnect to the unit.
• Dahua assumes no liability or responsibility for any fire or electrical shock caused by improp er
handling or installation.
Environmental Precautions
• Transport, use, and store the unit within the specified temperature and humidity range.
• Do not place the unit in a wet, dusty, extremely hot or an extremely cold environment; and avoid
environments with strong electromagneti c radiation or unstable lighting.
• Never push objects of any kind into this unit through openi ngs as they may touch dangerous
voltage points or cause a short circuit that may result in fire or electrical shock. Take care to not
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. T hese 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, st oves, 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 t he uni t 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 adequ at e 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 wat er spill s t o the camera unit during
transportation, storage, and installation.
Operation and Daily Maintenance
• Do not touch the heat dissipation component of the unit. This part of the uni t is hot and may
cause a burn.
• Do not open or dismantle the device; there are no components that a user can fix or replace.
Opening the unit may cause water leakage or expose components to di rect light. Contact the
manufacturer or a qualified service representative to s ervice the camera or to replace a
component, including the desiccant.
• 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 particul arly dusty, use water to dilute
a mild detergent, apply the diluted detergent to a soft clot h, 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 surf ace coatin g or reduce the
working performance of the unit.
Warnings
• Change the default password after the initial login to protect the integrity of the network.
• Use the standard accessories provided by the manufacturer and ensure the unit is installed and
commissioned by qualified professionals.
