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 manufacturer's instructions and in accordance with applicable local codes.
  • All installation and operation must conform to your local electrical 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.
• 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 unit is operational only when the ON/OFF switch is in the ON position. The power cord is the main power 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 the unit.
• For external power supplied units, use only the recommended 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 should 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 terminal.
• Contact the local dealer or the power company to verify the correct power supply.
• Do not attempt to service the unit. Opening or removing covers 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 include, 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 the user correctly follows the proper operating procedures.
• Ensure a service technician uses replacement parts 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 caused 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 manufacturer. 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 improper 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 electromagnetic radiation or unstable lighting.
- Never push objects of any kind into this unit through openings 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. 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 transportation, storage, and installation.

Operation and Daily Maintenance

• Do not touch the heat dissipation component of the unit. This part of the unit 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 direct light. Contact the manufacturer or a qualified service representative to service 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 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.

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.
