4 APPENDIX Ⅰ LIGHTENING PROTECTION AND SURGE

PROTECTION

This series speed dome adopts TVS lighting protection technology. It can effectively prevent

damages from various pulse signals below 2000W, such as sudden lighting and surge. While

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.

 In area of strong thunderstorm hit or near high sensitive voltage (such as near high-voltage

transformer substation), you need to install additional high-power thunder protection device

or lightning rod.

 The thunder protection and earth of the outdoor device and cable shall be considered in the

building whole thunder protection and conform to your local national or industry standard.



System shall adopt equal-potential wiring. The earth device shall meet anti-jamming and at

the same time conforms to your local electrical safety code. The earth device shall not short

circuit to N (neutral) line of high voltage power grid or mixed with other wires. When connect

the system to the earth alone, the earth resistance shall not be more than 4Ω and earth

cable cross-sectional area shall below 25 mm2.
