Best wifi outdoor dome camera 2.8mm lens please?

[adamfarber]

Hi all, I am sure questions like this have been posted before. I am going to set up a new camera system for my son in his house (not huge, a little under 2,000 s/f) and Ethernet may be tricky to run so looking at getting 6 WiFi cameras, outdoor, dome type, maybe 4mp, 2.8mm lens ( dont need zoom or PTZ). Any suggestion for good working ones with Excellent comparability with BI5?

Thanks, Adam in Florida
