1 Welcome
This manual offers reference material and general information about the basic operation,
maintenance, and troubleshooting of a Dahua Network PTZ Camera. Read, follow, and retain the
following safety instructions. Heed all warning 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.
•Ensure power conforms to SELV (Safety Extra Low Voltage) 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 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 supply power via the Ethernet connection (PoE) when power is already supplied via the
power connector.
•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 AC power supply and
from the PoE 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 camera.
•Dahua assumes no liability or responsibility for any fire or electrical shock caused by improper
handling or installation.
Environmental Precautions
•Do not aim the unit at a strong light source or into direct sunlight to focus. A strong light source
may cause overexposure and may affect the longevity of the CCD or the CMOS sensor.
•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.
•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.
•Do not touch the CCD or the CMOS optic sensor. Use a blower to clean dust or dirt on the lens
surface. Use a dry cloth dampened with alcohol and gently wipe away any dust on the lens.
•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.
•Do not touch or wipe a dome cover during installation, this cover is an optical device. Refer to
the following methods clean the dome cover:
•Stained with dirt: Use an oil-free soft brush or blower to gently remove the dirt.
•Stained with grease or fingerprints: Use a soft cloth to wipe gently the water droplet or the oil
from the dome cover. Then, use an oil-free cotton cloth or paper soaked with alcohol or
detergent to clean the lens from the center of the dome to outside. Change the cloth several
times to ensure the dome cover is clean.
Lifting Appliance Requirement
•Select the proper PTZ dome installation mode and use the proper lifting device to safely lift the
camera at the installation site.
•Ensure that the lifting device has the proper capacity to reach the installation height.
•Use the lifting device in accordance with its operating instructions and abide by the device’s
safety precautions.
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.
•Protect the lens area from laser radiation when using a laser device to aid in installation and
leveling of the unit.
•Do not supply power via the Ethernet connection (PoE) when power is already supplied via the
power connector.

3.3 Alarm Setup
Certain devices support alarm inputs and outputs, check your specific device for alarm capability.
Alarm Input
Refer to Figure 3-3 for alarm input configuration. The device collects that status of the alarm input port
when the input signal is idle or grounded. If the input signal is connected to the 3.3 V or it is idle then
the device receives the alarm input signal. If input signal is grounded, then no alarm input signal is
detected.
Figure 3-2
Alarm Output – Level Application
Use this alarm output configuration if the output triggers an external device by increasing the voltage.
The alarm must increase the external pull-up resistance to trigger (high level) the device. The
maximum external pull-up level is 5 V and the maximum port current is 5 mA. Once the output
increases the pull-up resistance, the alarm decreases the output voltage to the normal state (low level)
at less than 0.8 V.
