I got one of these a few days ago during the last woot-off. I had a bit of trouble with the software.
After wrestling a while with the camhi.top site, I was finally able to install the PC viewer. I was also able to download the VIPCAM app onto my android phone. Both work well. (Though I do wish the zoom function was operable.)
BUT, the app is not compatible with my Nexus tablet (rec'd in a Basket of Chocolate.) and there is no app in the store that I can find for my Amazon Fire tablet. I really wanted to be able to view this cam on my tablets.
Otherwise, I'm satisfied. But if anyone knows a generic app compatible with this cam, I'm all ears (eyes).
