Dear good afternoon, I have a problem that happens to me for the first time after several installations, it turns out that when we finish installing the entire camera system and when we orientate them we find that when you touch them they produce a discharge, a quite strong tingling, Turn off the entire system to prevent breakage. Do not place the ground wire that the DVR brings in the chassis of the system, can the problem be solved by placing the grounding wire? From already thank you very much

Obviously yes. For that it is just the ground wire.

Good. You have to put the whole system to ground, DVR and cameras, some UTP cables bring as a kind of aluminum wire, for that it is also, to put everything to ground. Greetings.
