• If a corrugated pipe is installed, a drainage hole should be deployed at the lowest point of the pipe to prevent
water from getting into the pipe. Long-term soaking may cause pigtail damage.
若安装波纹管，请在波纹管的最低点做排水孔处理，避免波纹管内积水，导致摄像机尾线长期浸泡导致损坏。
Cover the rest of the cabling in a conduit or with
protective waterproof rubber tape. Make a drip
loop as shown below to create an artificial lowest
point of the cable.
使用防护皮管或者防水胶带，包住线缆其他部分，并制
作滴水弯。滴水弯呈倒 Ω 型，形成线缆的最低点。

Wrap one layer of insulation tape around each
cable joint.Stretch the waterproofing tape evenly to
twice its original length. Then apply it for three layers
from bottom to top, from top to bottom, and from
bottom to top again.
用绝缘胶带缠绕每条线缆对接处，缠绕一层。均匀拉伸
防水胶带，使其长度为原长度的2倍。再采用由下至上，
由上至下，再由下至上的处理方式缠绕三层。
Apply three layers of insulation tape. Then, use
cable ties to secure the both ends.
用绝缘胶带缠绕三层。最后用扎线带绑扎上下两端。
