I purchased this, and spent a day installing it to replace my old camera system. Upgrading from 1mp to 8mp is a huge upgrade, and it is a well put together unit, easy to adjust. My only gripe, is for play back, it is nowhere as easy to use as my nest cameras. Could do with a software upgrade to make playback super easy. I didn't see any package detection or people detection in the UI like my Nest has.
