Are these cameras wireless?  

MV21 and MV71 require a standard Ethernet cable and PoE (for MV21) or PoE+ (for MV71) to operate.nnAll second generation cameras (MV12, MV22, MV72 and MV32) can be used with standard Ethernet and PoE, but they also feature 802.11ac wireless.nnMeraki also has power injectors available for users who do not have a PoE enabled switch available.n
