Apologies for what might be a 'just google it' question but I've just bought a DS-2CD2347G2-L(U) because my car got vandalised the other night and want to get it up and running asap (it's arriving in a few days time). And that's the long lead time item. Now I'm working out how to power it, either by PoE or by 12V. I'm planning to add a PoE box because I'm going to get a second camera in the future however to get me up and running quickly I wonder if I could just get a power supply and connect wirelessly? I've looked on the specifications for this camera from several sites but can't see it mentioning wifi anywhere. So my guess is it's wired connectivity only but if anyone could confirm that for me I'd be much obliged.
