Surge protector for IP camera

[Mandy 0]

I was just wondering if the IP camera mounted on the edge of the building and wall mounted, do I still need to have a surge protector?

My understanding is it required if camera installed on a pole?

please let me know your feedback.

 

thanks

It depends on your attitude to risk.

 

Technically, any camera mounted on the outside of the building should be installed with lightning protection connected to building earth on all cables.

The answer is always based in an answer to this question. What may be a good path to earth ground?

 

For example, if a wire connects two separate structures, then a wire leaving or entering must connect to that structure's single point earth ground before entering or connecting to anything on/in that structure. That rule applies to every wire inside every cable.

 

A tech note demonstrates the concept:

http://www.erico.com/public/library/fep/technotes/tncr002.pdf

Two structures (a building and tower) must each have their own single point earth ground. Any wire interconnecting the two must first connect to earth ground (either directly or via a protector) before entering the structure.

 

To make both earth grounds even better, a buried ground wire interconnects the single point earth grounds.

 

In your case, replace the tower with a camera. You mist implement a similar solution. If you do not, then a lighting strike to one structure may find a best path to earth destructively via electronics in the other structure.

 

Your answer is found in the question: what can be the best path to earth?
