Appendix I Lightning Protection and Surge Protection

Lightning and surge protection shall be considered for outdoor cameras. On the premise of

ensuring electrical safety, the following lightning protection measures can be taken:


The signal transmission line must be kept at least 50 meters away from the high-voltage

equipment or high-voltage cable;


Outdoor wiring shall be routed under the eaves as much as possible;


For the open area, the sealed steel pipe must be buried for wiring, and the steel pipe shall be

grounded at one point, and the overhead wiring is absolutely prohibited;


In strong thunderstorm area or high induced voltage area (such as high-voltage substation),

additional high-power lightning protection equipment and lightning rod must be installed;


The lightning protection and grounding design of outdoor devices and lines must be considered

in combination with the lightning protection requirements of buildings, and meet the

requirements of relevant national standards and industry standards;


The system must be equipotential grounded. The grounding device must meet the double

requirements of system anti-interference and electrical safety, and shall not be short circuited or

mixed connected with the zero line of the strong current network. When the system is grounded

separately, the grounding impedance shall not be greater than 4 Ω, and the cross-sectional area

of the grounding conductor shall not be less than 25mm2.
