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.
