the Camera in outdoor environment.
●
For vast land, use sealing steel tube under the land to implement cable layout and make sure
that both ends of the tube are equipotentially grounded. Open floor cable layout is forbidden.
●
In area of strong thunderstorm or near high sensitive voltage (such as near high-voltage
transformer substation), install additional high-power thunder protection device or lightning rod.
●
The system shall adopt equal-potential wiring. The grounding devices shall meet anti-jamming
requirements and at the same time conforms to your local electrical safety code.
●
The grounding devices shall not be connected to N (neutral) line of high voltage power grid or
mixed with other wires. When you connect the system to the ground alone, the grounding
resistance shall not be more than 4 Ω and the cross-sectional area of grounding cable shall be no
less than 25 mm
