ADC - v722w vs. ADC V720

I’m looking at upgrading the video on my system. I currently have two ADC V720 camera’s. What is the major difference between the 722 and the 720… Anything besides the 722 records in HD. 722 is significantly cheaper than 720 and looking to add a couple of more and made me wonder.

The 722W does have improved resolution. Both are HD. 1080P for the 722W, 720P for the 720W. It also uses a plastic housing and mount. Most specs are similar. The V722W has a bit wider field of view.
