maintaining your local electrical safety code, you still need to take necessary precaution
measures when installing the speed dome in the outdoor environment.






The distance between the signal transmission cable and high-voltage device (or high-voltage
cable) shall be at least 50 meters.
Outdoor cable layout shall go under the penthouse if possible.
For vast land, please use sealing steel tube under the land to implement cable layout and
connects one point to the earth. Open floor cable layout is forbidden.
