A few years ago I purchased some goowls brand outdoor cameras on Amazon. They no longer sell that brand. Now all worked on the yi iot app. I love that app. I added another goowls I found on eBay and all run fine. But last month I lost one of my original ptz cameras. Searched through Amazon and found a brand by meco. Copy stated it will work on the yi iot app. Not a chance. No support from seller or manufacturer. Sending back.
