liquid, gas, or solid substances.

• Do not let the product get wet or rained on. Do not use it beyond the limit of temperature and

humidity.

• When cleaning the lens, please use a soft dry cloth to wipe. When there is a lot of dust, please

use a neutral cleaner and wipe gently.

• Do not use a strong or corrosive detergent to avoid scratching the lens and affecting the image.

• This product has no parts that users can repair by themselves, and the damage caused by users

‘self-disassembly does not fall within the scope of warranty.

2. Electrical safety

• The installation and use of products must strictly comply with the national and local electrical safety

standards.

• Do not use power adapters beyond the specifications of the power supply, otherwise the

equipment components will burn out and will not work properly.

• In the process of using the product, we should keep enough distance from the high-power

equipment, and do a good job of lightning protection, surge protection and other protective

measures when necessary.

• When the product is not in use, please disconnect the power switch and

3. Installation Safety

• Do not rotate the cylinder of the product by hand, otherwise it will destroy the

rotating shaft of the structure.

• Installation and placement of equipment should be horizontal and stable, and the
