Important Safeguards and Warnings
Electrical Safety
All installation and operation shall 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.
Note that the power supply requirement is subject to the device label.
Make sure that the power supply is correct before operating the device.
A readily accessible disconnecting 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, dusty extremely hot or cold environment, 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 manual when performing any disassembly operation about
the device; otherwise, it might cause water leakage or poor image quality due to unprofessional
disassembly. Please make sure that the gasket ring is flat and properly installed in the groove before
installing the cover. Please contact after-sale service for desiccant replacement if there is condensed
fog on the lens after unpacking or when the desiccant turns green (Not all models are included with
the desiccant).
It is recommended to use the device together with lightning arrester to improve lightning protection
effect.

Quick Start Guide
IV
It is recommended to ground the device to enhance reliability.
Do not touch the image sensor (CMOS) directly. Dust and dirt could be removed with air blower, or
you can wipe the lens gently with soft cloth that is moistened with alcohol.
You can clean the device body with soft dry cloth, and for stubborn stains, use the cloth 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
moistened oil-free cotton with diethyl or moisten soft cloth. You can also remove dust with an air
blower.
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 that 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.
