Important Safeguards and Warnings III
Important Safeguards and Warnings
Electrical Safety
All installation and operation should conform to your local electrical safety codes.
The power source shall conform to the Safety Extra Low Voltage (SELV) standard, and
supply power with rated voltage which conforms to Limited power Source requirement
according to IEC60950-1. Please note that the power supply requirement is subject to the
device label.
Make sure the power supply is correct before operating the device.
A readily accessible disconnect device shall be incorporated in the building installation
wiring.
Prevent the power cable from being trampled or pressed, especially the plug, power socket
and the junction extruded from the device.
Environment
Do not aim the device at strong light to focus, such as lamp light and sun light; otherwise it
might cause over brightness or light marks, which are not the device malfunction, and
affect the longevity of Complementary Metal-Oxide Semiconductor (CMOS).
Do not place the device in a damp or dusty environment, extremely hot or cold
temperatures, or the locations with strong electromagnetic radiation or unstable lighting.
Keep the device away from any liquid to avoid damage to the internal components.
Keep the indoor device away from rain or damp to avoid fire or lightning.
Keep sound ventilation to avoid heat accumulation.
Transport, use and store the device within the range of allowed humidity and temperature.
Heavy stress, violent vibration or water splash are not allowed during transportation,
storage and installation.
Pack the device with standard factory packaging or the equivalent material when
transporting the device.
Install the device in the location where only the professional staff with relevant knowledge
of safety guards and warnings can access. The accidental injury might happen to the
non-professionals who enter the installation area when the device is operating normally.
Operation and Daily Maintenance
Do not touch the heat dissipation component of the device to avoid scald.
Carefully follow the instructions in the Guide when performing any disassembly operation
about the device; otherwise, it might cause water leakage or poor image quality due to
unprofessional disassemble. Please contact after-sale service for desiccant replacement if
there is condensed fog found on the lens after unpacking or when the desiccant turns
green. (Not all models are included with the desiccant).

Important Safeguards and Warnings IV
It is recommended to use the device together with lightning arrester to improve lightning
protection effect.
It is recommended to ground the device to enhance reliability.
Do not touch the image sensor directly (CMOS). Dust and dirt could be removed with air
blower, or you can wipe the lens gently with soft cloth that moistened with alcohol.
Device body can be cleaned with soft dry cloth, which can also be used to remove
stubborn stains when moistened with mild detergent. To avoid possible damage on device
body coating which could cause performance decrease, do not use volatile solvent such as
alcohol, benzene, diluent and so on to clean the device body, nor can strong, abrasive
detergent be used.
Dome cover is an optical component, do not touch or wipe the cover with your hands
directly during installation or operation. For removing dust, grease or fingerprints, wipe
gently with moisten oil-free cotton with diethyl or moisten soft cloth. You can also air blower
to remove dust.
Please strengthen the protection of network, device data and personal information by
adopting measures which include but not limited to using strong password, modifying
password regularly, upgrading firmware to the latest version, and isolating computer
network. For some device with old firmware versions, the ONVIF password will not be
modified automatically along with the modification of the system password, and you need
to upgrade the firmware or manually update the ONVIF password.
Use standard components or accessories provided by manufacturer and make sure the
device is installed and maintained by professional engineers.
The surface of the image sensor should not be exposed to laser beam radiation in an
environment where a laser beam device is used.
Do not provide two or more power supply sources for the device unless otherwise specified.
A failure to follow this instruction might cause damage to the device.
