Use the waterproof tapes to protect the end of tail cable, and keep

the tail cable from water.
When connecting to an external interface, use an existing

connection terminal, and ensure that the cable terminal (latch or
clamp) is in good condition and properly fastened. Ensure that the
cable is not tense during mounting, with a proper margin reserved
to avoid poor port contact or loosening caused by shock or shake.
Make sure the power supply voltage is correct before using the

camera.
To keep the dome clean, do not remove the protective film on the

outer layer of the housing during mounting. After finishing the
mounting, remove the film before you power on the camera.
As is often the case in the industry, dome housings tend to carry

static electricity. To avoid dust absorption caused by static
electricity, it is recommended to clean the dome housing with
antistatic gloves after removing the protective film.
Power off the camera before cleaning the housing, wipe the

internal and outside surfaces using soft dry cloth. Do not use liquid
or aerosol cleaners.
Avoid letting the lens focus on bright-light objects, especially the

sun or other bright-light sources. Otherwise, the imaging sensor of
the camera may be completely broken.
Do not touch sensor modules with fingers. If cleaning is necessary,

use a clean cloth with a bit of ethanol and wipe it gently. If the
camera will not be used for an extended period of time, put on the
lens cap to protect the sensor from dirt.
Do not aim the camera lens at the strong light such as sun or

incandescent lamp. The strong light can cause fatal damage to the
camera.
