QUOTE(alexander3133 @ Dec 9 2016, 07:12 AM) I have not much experience on lightning arrestor or lightning isolator, but you can ask around or wait for other people reply. 6kv I remembered that the Hikvision network camera has 6kV lightning protection, I saw the words written in the packaging, but not in the specification on their website. Better still to have another layer of protection just to be safe.   that don't seem to be a lighting protection circuit maybe good for incoming surge but not lighting. Lighting is many more time of that and depending on the strength and area too. http://www.windpowerengineering.com/featur...t-of-lightning/ |

QUOTE(alucard89 @ Dec 9 2016, 02:30 AM) Hi, what can I get to protect my CCTV cameras/nvr from getting fried if lightning struck? Been using Cal-Lab, is good so far. at my mom house, only cal-lab managed to protect my dsl modem, the other brand i try it fried together with the modem. Proble with Cal-lab need to pay small fees for a replacement. Is something like this sufficient enough? https://forum.lowyat.net/topic/272679 From another lowyat thread, they seem to recommend Cal Lab brand over belkin https://forum.lowyat.net/index.php?showtopi...post&p=66449443 For the past few years when thunder strikes, only my router that's connected to modem that's either fried or LAN port damaged. So I'm kinda worried it might damage my cameras when I'm using wired POE LAN system Any lighting protection, it have to be protected at the point of entry of lighting (usually is electric source, antenna, and long running conductor like wires) |
