Need recommendations, IP/Wifi Cams for RV park

Okay, trying to set this up for a business, they want 32 cams, wifi and wired, mostly wifi, but I have no idea on what is a good system and what are good prices for cameras? I am looking at 2MP IP cameras for ~$119/each, they are ONVIF Sony cams that come with 2.4ghz wifi antenna. The NVR is a 32ch 960P system (does 24ch at 1080P)

Any ideas if this is good or bad? Recommendations? Decent sized RV park spanning atleast 200'+ feet - I have wifi repeaters placed throughout the park to bounce the signals, just need an idea of what to purchase.

(here is the site I was looking at for reference: http://www.videocamerasecurity.net/)

Office is at the bottom near the storage, that is where all the equipment, routers/etc will be stored.

Thanks in advanced!
