Review on Dericam Outdoor WiFi PTZ Security Camera - 1080P Full HD, 4X Optical Zoom, Night Vision, Motion Detection and pre-installed 32GB Memory Card by Brian Malith

I bought at least 7 S1 cameras and 2 S2 1080P cameras. I didn't notice any difference between the different camera types and it's not worth paying extra for the S2 type. I was disappointed with the S2 and thought I had a better resolution but I didn't get it. There are no additional resolution settings in the software utilizing 1080P for S2. When I compared them side by side, I just didn't see any difference, either near or far. Disappointed with this product.
