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 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.
