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).

It is recommended to use the device together with lightning arrester to improve lightning
